Further, the product information screen 520 is provided with a purchase number display section 522, a plus button 523, a minus button 524, a cart insertion button 525, and a cancel button 526. The purchase quantity display section 522 displays the purchase quantity of the product, and the user U can change the purchase quantity by touching the plus button 523 or the minus button 524. In addition, when the user U completes the input of the number of purchases, the user U can touch the cart insertion button 525 to input products for the number of purchases into the electronic cart. When the control unit 31 detects a touch operation on the cancel button 526 (step S7: NO), cart non-registration data (data including the product ID of the product) indicating that the product has not been put into the cart. Is transmitted to the shopping server 1, and the process proceeds to step S2. On the other hand, when the shopping server 1 receives the cart non-registration data, it generates history information only for the inquiry and registers it in the user DB 122.

  When detecting a touch operation on the cart insertion button 525 on the product information screen 520 (step S7: YES), the control unit 31 performs a cart registration process (step S8). Specifically, the control unit 31 generates electronic cart information based on the product name, product ID, number of purchases, and price displayed on the product information screen 520 when the cart insertion button 525 is touched. Or update. In addition, the control unit 31 transmits cart registration data (data including the product ID of the product) indicating that the product has been registered in the cart to the shopping server 1 and proceeds to the process of step S2. On the other hand, when the shopping server 1 receives the cart registration data, the shopping server 1 generates cart insertion history information and registers it in the user DB 122.

  When the control unit 31 detects not a touch operation on the product reading area 511 on the menu screen 510 (step S3: NO) but a touch operation on the cart browsing area 512 on the menu screen 510 (step S9: YES), FIG. Is displayed on the touch panel 34 (step S10). The cart screen 530 displays the product name, price, number of purchases, subtotal (price x number of purchases) of the products registered in the electronic cart, and the total amount. At this time, the control unit 31 calculates and displays the subtotal and the total amount from the price and the number of purchases. The cart screen 530 is provided with a return button 531. When the control unit 31 detects a touch operation on the return button 531, the process proceeds to step S2.

  Returning to FIG. 9, the control unit 31 detects a touch operation on the purchase history browsing area 514 on the menu screen 510 instead of a touch operation on the cart browsing area 512 on the menu screen 510 (step S9: NO) (step S11). : YES), the purchase history screen 540 shown in FIG. 13 is displayed on the touch panel 34 (step S12). At this time, when displaying the purchase history screen 540, the control unit 31 first transmits the mobile ID of the mobile terminal 3 to the shopping server 1. On the other hand, when receiving the mobile ID from the mobile terminal 3, the control unit 11 of the shopping server 1 acquires purchase history information from the user DB 122 based on the received mobile ID and sends it back. And the control part 31 of the portable terminal 3 displays the purchase history screen 540 based on the purchase history information received from the shopping server 1.

  In the purchase history screen 540, when the user U has purchased a product in the past, the store name and telephone number of the store, the date and time of entering the store, the date and time of accounting at the store, and the product purchased at the store The product name, price, number of purchases, subtotal (price x number of purchases), total amount (payment amount), etc. are displayed. The purchase history screen 540 is provided with a return button 541. When the control unit 31 detects a touch operation on the return button 541, the control unit 31 proceeds to the process of step S2. When there are two or more purchase histories of the user U, for example, a “next one” button or a “previous one” button is provided in the purchase history screen, and the user U views each purchase history. It can be so.

  Returning to FIG. 9, the control unit 31 detects a touch operation on the accounting area 513 on the menu screen 510 instead of a touch operation on the purchase history browsing area 514 on the menu screen 510 (step S11: NO) (step S13: YES), the accounting screen 550 shown in FIG. 14 is displayed on the touch panel 34 (step S14). On the other hand, the control part 31 transfers to the process of step S3, when the touch operation to the accounting area | region 513 in the menu screen 510 is not detected (step S13: NO).

  On the accounting screen 550, a message is displayed asking the user U whether or not to check the products that the user U has put into the electronic cart at the cash register (accounting apparatus 5). Below the message, a “confirm at the cash register” area 551 and an “not confirm at the cash register” area 552 are provided, and the control unit 31 performs a touch operation on the “confirm at the cash register” area 551. When detected, the “confirm with checkout” check box 551C is filled in. On the other hand, when the touch operation to the “not confirm with register” area 552 is detected, the “do not confirm with register” check box 552C is filled out. As a result, the user U can confirm whether the item that has been put into the electronic cart is selected to be confirmed at the cash register (accounting device 5) or not to be confirmed at the cash register. . In addition, on the accounting screen 550, a payment amount calculated from the price and the number of purchases of the product put in the electronic cart is displayed. Further, the accounting screen 550 displays a message that prompts the user U to place the mobile terminal 3 on the mounting table of the accounting reader / writer 4.

  Next, the control unit 31 maintains the radio wave detection state until the non-contact IC chip 36 detects the radio wave output from the accounting reader / writer 4 (step S15: NO), and when the radio wave is detected (step S15). S15: YES), accounting processing is performed (step S16). Specifically, the control unit 31 transmits electronic cart information indicating a list of products put in the electronic cart to the accounting device 5 via the accounting reader / writer 4. In addition, the control unit 31 transmits to the accounting apparatus 5 registration confirmation information indicating whether “confirm at the cash register” or “not confirm at the cash register” is selected on the accounting screen 550.

  On the other hand, when receiving the electronic cart information and the cash register confirmation information, the control unit 51 of the accounting apparatus 5 displays a payment method selection screen on the touch panel 54. Specifically, when receiving checkout information indicating that “confirm at checkout” is selected on the transaction screen 550, the control unit 51 pays the payment method selection screen 610A shown in FIG. Is displayed. On the other hand, when cashier confirmation information indicating that “do not confirm at cash register” is selected on the accounting screen 550, a payment method selection screen 610B shown in FIG. 15B is displayed.

  The payment method selection screens 610A and 610B are screens for allowing the user U to select a payment method (settlement method), and an electronic money payment button 613, a credit card payment button 614, and a cash payment button 615 are provided at the bottom of the screen. ing. In addition, on the payment method selection screen 610A shown in FIG. 15A, a list (product name, price, quantity, subtotal) 611 of products put into the electronic cart is displayed based on the electronic cart information. In the payment amount display column 612, the total number of purchases and the total payment amount are displayed. On the other hand, on the payment method selection screen 610B shown in FIG. 15B, the list of products 611 is not displayed, and the payment amount is displayed in the payment amount display section 616 instead of the payment amount display field 612. After confirming the payment amount, the user U touches the electronic money payment button 613, the credit card payment button 614 or the cash payment button 615 depending on the payment method.

  When the control unit 51 of the accounting apparatus 5 detects a touch operation on the electronic money payment button 613, the credit card payment button 614, or the cash payment button 615, the control unit 51 performs processing corresponding to each settlement method. The contents of processing when electronic money settlement, credit card settlement, or cash settlement is selected are as described above. When the payment process is completed, the control unit 51 transmits a payment completion notification indicating that the payment process is completed and payment method information indicating the payment method to the mobile terminal 3. Moreover, the control part 51 outputs a sound from the speaker which is not shown in figure, and notifies the user U that the payment process was complete | finished.

  On the other hand, when receiving the payment completion notification from the accounting apparatus 5, the control unit 31 of the portable terminal 3 transmits the electronic cart information and the payment method information to the shopping server 1 and ends the processing in this flowchart. On the other hand, when receiving the electronic cart information and the payment method information from the mobile terminal 3, the control unit 11 of the shopping server 1 generates purchase history information and registers it in the user DB 122.

  As described above, the shopping system S according to the present embodiment includes the mobile terminal 3 (an example of “mobile terminal device”) and the reader / writer 2 for entering a store installed in a store (an example of “store device”). And a shopping server 1 (an example of “server device”) and an accounting device 5 (an example of “accounting device”). The storage unit 12 (an example of “price storage unit”) of the shopping server 1 associates the price of a product with a store ID for identifying a store handling the product and a product ID for identifying the product. Remember. The control unit 11 (an example of “inquiry receiving means”, “price acquisition means”, and “price information transmitting means”) of the shopping server 1 receives the store ID and the product ID from the mobile terminal 3, and receives the received store ID and A price is acquired from the storage unit 12 based on the product ID, and price information indicating the acquired price is transmitted to the mobile terminal 3 that has transmitted the store ID and the product ID. In addition, the storage unit 22 (an example of “store ID storage unit”) of the reader / writer 2 for entering a store stores the store ID, and the control unit 21 (an example of “store ID transmission unit”) is stored in the storage unit 22. The store ID is transmitted to the portable terminal 3. Further, the control unit 31 (an example of “store ID receiving unit”, “product ID acquisition unit”, “inquiry transmission unit”) of the mobile terminal 3 receives the store ID transmitted from the reader / writer 2 when entering the store. The barcode B displayed for the product is read, the product ID of the product is acquired, and the received store ID and the acquired product ID are transmitted to the shopping server 1. Next, the control unit 31 (an example of “price information receiving means”, “price display control means”, “payment amount calculation means”, “payment amount transmission means”) receives the price information transmitted from the shopping server 1. The price indicated by the received price information is displayed on the touch panel 34 (an example of “display means”), and the price of the product selected by the user U is calculated from the products for which the price is displayed. Then, the payment amount information indicating the calculated payment amount is transmitted to the accounting apparatus 5. Furthermore, the control unit 51 (an example of “payment amount receiving means”) of the accounting apparatus 5 receives the payment amount information transmitted from the mobile terminal 3.

  According to this shopping system S, the portable terminal 3 sends the store ID transmitted from the store reader / writer 2 and the product ID acquired by reading the barcode B displayed for the product to the shopping server 1. The price of the product is acquired by transmission and displayed on the touch panel 34. Further, the mobile terminal 3 calculates the payment amount by adding the prices of the products selected by the user U among the products for which the prices are displayed, and transmits the payment amount to the accounting device 5.

  Accordingly, the user U causes the portable terminal 3 to receive the store ID transmitted from the reader / writer 2 at the time of entering the store, and displays the price by reading the barcode B of the product of interest with the portable terminal 3. The price of the product can be grasped on the product information screen 520. Further, when the user U selects a product to be purchased from among the products whose prices are displayed, a payment amount in which the prices of the selected products are totaled is calculated and transmitted to the accounting apparatus 5. That is, the store side does not need to attach an IC tag to the product, and the user U does not need to read the bar code B by the accounting device 5, so that the accounting can be completed smoothly.

  In addition, the control unit 31 (an example of “purchase history information transmission unit”, “purchase history information acquisition unit”, and “display control unit”) of the mobile terminal 3 performs the settlement for the product selected by the user U. When the purchase history information related to the settlement and the mobile ID (an example of “user ID”) used to identify the user U are transmitted to the shopping server 1 and the purchase history information is requested to be browsed, Purchase history information is acquired based on the ID, and the acquired purchase history information is displayed on the touch panel 34. Thereby, the user U can confirm the purchase history on the mobile terminal 3.

  In addition, the control unit 31 (an example of “non-selected product ID transmission unit”) of the mobile terminal 3 selects a product canceled by the user (“not selected” from among the products whose prices are displayed on the product information screen 520. The cart non-registration data including the product ID (an example of “non-selected product ID”) for identifying the “product”) is transmitted to the shopping server 1. On the other hand, the storage unit 12 of the shopping server 1 (an example of “non-selected product ID storage unit”) stores the product ID included in the cart non-registration data received from the mobile terminal 3 as part of the history information only. Thereby, among the products whose prices are displayed on the mobile terminal 3, the product ID of the product that is not selected by the user (that is, the product that the user is interested in confirming the price but has not purchased) is the shopping server 1. Is stored in the storage unit 12, so that the store side can utilize it for marketing.

  In the present embodiment, the purchase history screen 540 receives and displays purchase history information from the shopping server 1, but the electronic cart information and the payment method when the control unit 31 of the mobile terminal 3 completes the payment process. Information may be stored in the storage unit 32 and the purchase history screen 540 may be displayed based on the stored information. In this case, information that cannot be displayed only by information stored in the storage unit 32, such as a telephone number of a store, may be obtained by inquiring the shopping server 1 or may not be displayed. .

  In this case, the control unit 31 (an example of “purchase history information recording unit” and “display control unit”) of the mobile terminal 3 purchases information related to the payment when the payment for the product selected by the user U is completed. The history information is stored in the storage unit 32 (an example of “purchase history information storage unit”), and when the purchase history information is requested to be browsed, the purchase history information stored in the storage unit 32 is displayed on the touch panel 34. Thereby, the user U can check the purchase history on the mobile terminal 3 without making an inquiry to the shopping server 1.

  In the present embodiment, the automatic checkout machine 6 is connected to the accounting apparatus 5, but the store clerk of the store ST may perform a credit card settlement service and a cash settlement service. In this case, although the work amount of the clerk increases, it is not necessary to install the automatic checkout machine 6. Therefore, the store ST only needs to install the relatively inexpensive entry reader / writer 2 and the accounting reader / writer 4 and can introduce the shopping system S without introducing expensive equipment.

  In this embodiment, the paper receipt issuance is not mentioned. However, the user U can select whether or not to issue the paper receipt on the payment method selection screens 610A and 610B, and the paper receipt can be selected. When the issue is selected, the accounting device 5 or the automatic checkout machine 6 may issue a paper receipt.

  Further, in the present embodiment, the electronic money settlement, the credit card settlement, and the cash settlement in the accounting device 5 are exemplified as the settlement method. However, the mobile terminal 3 may perform the Internet settlement. In this case, the control unit 31 (an example of “payment amount transmission means”) of the mobile terminal 3 uses the payment amount information indicating the calculated payment amount as an Internet settlement server (an example of “accounting terminal device”) that realizes an Internet settlement function. ). At this time, the Internet payment server makes a payment using assets held by the user U on the Internet (for example, points accepted at a store ST or a site operated by an affiliated company) or a pre-registered credit card To make a payment. Thereby, since the user U does not need to perform accounting with the accounting device 5, accounting can be completed smoothly.

  Moreover, it is good also as registering the word-of-mouth information from each user U with respect to the said goods and the recipe information which uses the said goods as the additional information of goods, and displaying on the goods information screen 520 in goods DB121.

  When the shopping application is not installed in the portable terminal 3 and the portable terminal 3 is held over the reader / writer 2 at the time of entering the store, the control unit 31 sends the shopping application from the reader / writer 2 at the time of entering the store. The installation site URL (Uniform Resource Locator) may be received, and the shopping application may be installed by accessing the URL.

[7. Countermeasures against illegal accounting]
In the store ST that introduced the shopping system S, by introducing an automatic checkout machine that supports electronic money payment, credit card payment, cash payment, etc., it is not necessary to have the store clerk present at the time of accounting, thereby reducing the number of people in charge of accounting There is an advantage that you can. On the other hand, in this case, the user U may take away without registering the product in the electronic cart (that is, without performing proper accounting). Therefore, in the following, two countermeasures against such illegal accounting will be described.

[7.1. Measures by member rank]
The first measure against fraudulent accounting is to divide accounting methods into two methods: full self and semi self. Semi-self is an accounting method in which a store clerk checks whether accounting is properly performed (a product registered in an electronic cart matches a product stored in an actual shopping basket). On the other hand, full self is an accounting method in which the user U does accounting with the accounting device 5 without checking whether the accounting is properly conducted. Accounting by full self can shorten the accounting time and is considered to be a preferable accounting method for the user U in using the shopping system S. Note that only self-accounting is permitted for users U whose membership rank set by the shopping system S is equal to or higher than a predetermined rank.

  In performing this measure, first, a member rank item is newly provided in the user DB 122 of the shopping server 1 so that the user U can be identified by referring to the user DB 122. As the member rank, a plurality of ranks (S rank, A rank, B rank, C rank, D rank, and E rank in this embodiment) are provided. The acquisition of the member rank by the portable terminal 3 is that the control unit 31 transmits its own portable ID to the shopping server 1 and returns the member rank corresponding to the portable ID received by the control unit 11 of the shopping server 1. Is done.

  Further, as in the product score table for each rank shown in FIG. 16 (a), the number of products for which semi-self accounting and full self-accounting are permitted are determined according to the member rank. For a member (user) whose member rank is C rank or less, full self-accounting is not permitted. On the other hand, up to 2 points for B rank members (users) and up to 5 points for A rank members (users) are allowed for self-assessment, and product scores for S rank members (users). Regardless of the number, full self-accounting is permitted. It should be noted that a product score table for each rank as shown in FIG. 16 (a) is provided for each store or each region to which the store belongs, and the product scores for which semi-self accounting and full self-accounting are permitted are different. Also good. For example, a store belonging to an area with a high number of shoplifting cases may change the setting value according to the area, such as reducing the number of products that allow full self-accounting than a shop belonging to an area with a low number of shoplifting cases. . Moreover, the product score table for each rank may be stored in the shopping application on the mobile terminal 3 side, or may be stored on the shopping server S side and appropriately referred to by the mobile terminal 3 (this book) The embodiment will be described from the former standpoint.)

  Further, as in the promotion condition table shown in FIG. 16B, promotion conditions to S rank, A rank, B rank, C rank, and D rank are defined. In the present embodiment, the promotion condition to each rank is determined based on the use years of the shopping system S and the total payment amount, and a member having a long use year and a large total payment amount moves to a higher rank. ing. That is, a higher member rank is assigned to a user with higher reliability. The management of the member rank is performed by the shopping server 1, and the control unit 11 promotes the member rank when the member (user) satisfies the promotion condition. These promotion conditions are only examples, and other conditions such as adding the number of visits to the promotion conditions can be set. In stores where a large number of personnel cannot be assigned to accountants, full self-accounting is possible. It is also possible to set conditions for each store, such as setting the promotion conditions low to promote the promotion. Moreover, it is good also as demoting a rank about the member (user) who was not used for a fixed period.

  During the activation of the shopping application, as shown in the example of FIG. 17, a member rank display area 561 is provided on various screens (FIG. 17 is an example of the accounting screen 560), and the rank of the user U's member rank is. Are displayed, and the number of products for which full self and semi self accounting is permitted is displayed according to the member rank. In addition, a “current score” display area 562 is provided, and the product score registered in the electronic cart at that time is displayed. The member rank display area 561 is acquired from the member rank acquired by the control unit 31 of the mobile terminal 3 from the shopping server 1 and the product score table for each rank based on the member rank (see FIG. 16A). The product score is displayed.

  Next, the flow at the time of accounting when measures based on member ranks are introduced will be described.

  First, when the control unit 31 of the mobile terminal 3 detects a touch operation on the accounting area 513 on the menu screen 510 in the process of step 13 of FIG. 9, the control screen 560 shown in FIG. S14).

  On the accounting screen 560, a message “Please select an accounting method” is displayed below the member rank display area 561 and the “current score” display area 562, and further below that, “Full Self ”Area 563,“ confirm product at cash register ”area 564, and“ semi-self ”area 565. The user U can select either full self payment or semi self payment by touching the “full self” area 563 or the “semi self” area 565. In addition, the user U can select to confirm the list of products registered in the electronic cart by the accounting device 5 by touching the “confirm products at the cash register” area 564. It has become. However, the “confirm product at the cash register” area 564 can be selected only when the “full self” area 563 is selected. When the control unit 31 detects a touch operation on the “full self” area 563, the “confirm product at the cash register” area 564, or the “semi-self” area 565, the “full self” check box 563C and “ The “confirm” check box 564C and the “semi-self” check box 565C are filled. Thereby, the user U can confirm which is selected.

  Regarding the display of the accounting screen 560, the control unit 31 does not permit full self accounting when the number of items registered in the electronic cart exceeds the limit of the number of items corresponding to the user U's membership rank. Therefore, the “full self” area 563, the “semi self” area 564, or both are controlled so that they cannot be selected (for example, grayed out or the area itself is not displayed). In addition, when the member rank of the user U is rank C or lower, the control unit 31 controls the display so that the “full self” area 563 cannot be selected in order to disable full self accounting. (For example, it is grayed out or the area itself is not displayed).

  In addition, an “electronic money” area 566, a “credit card” area 567, and a “cash” area 568 are provided on the accounting screen 560 below the message “Please select a payment method.” The user U can select any one settlement method (payment method). When the control unit 31 detects a touch operation on the “electronic money” area 566, the “credit card” area 567, or the “cash” area 568, the “electronic money” check box 566C and the “credit card” check box 567C, respectively. , “Cash” check box 568C is filled. Thereby, the user U can confirm which is selected.

  Next, after the user U selects an accounting method and a settlement method, when the portable terminal 3 is placed on the mounting table of the accounting reader / writer 4, accounting is performed according to the accounting method selected by the user on the accounting screen 560. Here, first, the flow when the full self accounting method is selected will be described using FIG. 18, and then the flow when the semi self accounting method is selected will be described using FIG.

  As shown in FIG. 18, when the full self accounting method is selected, when the mobile terminal 3 is placed on the placement table of the accounting reader / writer 4 by the user U (step S31), the electronic cart information and the cash register are registered. Confirmation information (information indicating whether or not the “confirm product at checkout” check box 564C is selected) and settlement method information indicating which settlement method is selected are transferred from the portable terminal 3 to the accounting apparatus 5. It is transmitted (step S32).

  The control unit 51 of the accounting apparatus 5 refers to the cash register confirmation information received from the mobile terminal 3 and determines whether or not the “check merchandise at cash register” check box 564C is selected (step S33). When it is determined that the control unit 51 has not been selected (step S33: NO), the control unit 51 performs payment according to the payment method indicated by the payment method information received from the mobile terminal 3 (step S35). On the other hand, when the control unit 51 determines that the “confirm product at the cash register” check box 564C is selected (step S33: YES), the control unit 51 performs FIG. 19 based on the electronic cart information received from the mobile terminal 3. Is displayed on the touch panel 54 (step S34).

  On the payment method selection screen 620, the above-mentioned list of products 611 and the payment amount display column 612 (see FIG. 15A) are displayed, and on the lower left side thereof, the payment method information received from the mobile terminal 3 is displayed. The settlement method shown (that is, the settlement method selected by the user U on the accounting screen 560) is displayed. On the right side, a confirmation button 621 to be touched after the user U confirms the purchased product, the payment amount and the payment method is provided. Further, the payment method selection screen 620 is provided with an electronic money payment button 613, a credit card payment button 614, and a cash payment button 615 so that the payment method selected by the user U on the accounting screen 560 can be changed. Yes. However, the payment buttons 613 to 615 are not necessarily provided.

  When the control unit 51 of the accounting apparatus 5 detects a touch operation on the electronic money payment button 613, the credit card payment button 614, or the cash payment button 615, the control unit 51 performs processing according to each settlement method, while the confirmation button When a touch operation on 621 is detected, processing corresponding to the previously selected settlement method (that is, the settlement method selected on the accounting screen 560) is performed (step S35).

  Next, the flow when the semi-self accounting method is selected will be described with reference to FIG. When the semi-self accounting method is selected and the mobile terminal 3 is placed on the mounting table of the accounting reader / writer 4 by the user U (step S51), the electronic cart information and the settlement method information are stored in the mobile terminal 3 To the accounting device 5 (step S52). On the other hand, the control unit 51 of the accounting apparatus 5 displays the product list screen 630 shown in FIG. 21 on the touch panel 54 based on the electronic cart information received from the mobile terminal 3 (step S53).

  The product list screen 630 is a screen for checking whether or not the product stored in the actual shopping basket matches the product registered in the electronic cart. That is, on the product list screen 630, the product name 631, the number of purchases 632, the unit price 633, and the subtotal 634 are displayed for each product registered in the electronic cart based on the electronic cart information. Further, a product image 635 is displayed so that the store clerk can quickly compare the product displayed on the product list screen 630 with the product that the user U is actually purchasing. The product image 635 is associated with the product ID and stored in a predetermined storage device (for example, the storage device in the accounting device 5 or the storage unit 12 in the shopping server 1), and stored when the product list screen 630 is displayed. Obtained from the device and displayed. In addition, the product list screen 630 is provided with a check box 631C for each product, and the store clerk examines the shopping basket delivered from the user U and displays the product displayed on the product list screen 630 for the product contained therein. When it is confirmed that the name and the number of purchases match, the corresponding check box 631C is touched. Thereby, the store clerk can grasp at a glance which product is checked. The product list screen 630 displays the number of products registered in the electronic cart and the total price, and further includes a confirmation button 631 to be touched when the store clerk completes the check. It has been.

  When the clerk completes the check for all the products (step S54), the clerk performs a touch operation on the confirmation button 631. When detecting a touch operation on the confirmation button 631, the control unit 51 of the accounting apparatus 5 displays the payment method selection screen 620 shown in FIG. 19 on the touch panel 54 (step S55). If the payment method (payment method) selected on the accounting screen 560 is acceptable, the user U performs a touch operation on the confirmation button 621. On the other hand, when changing the payment method, the electronic money payment button 613, the credit card A touch operation is performed on the payment button 614 or the cash payment button 615 (step S56). These operations may be performed by the store clerk confirming the payment method with the user U. When the control unit 51 of the accounting apparatus 5 detects a touch operation on the confirmation button 621, the electronic money payment button 613, the credit card payment button 614, or the cash payment button 615, the control unit 51 performs a process according to each settlement method (step S57). .

  By the way, if the number of items registered in the electronic cart exceeds the number of items for which full self-accounting corresponding to the member rank of the user U is permitted (the impossible condition is satisfied), There is a need for control that makes accounting impossible. As a control method, as described above, there is a method of preventing full self-accounting from being selected on the accounting screen 560 when the impossible condition is satisfied. In addition, for example, the accounting screen 560 may be configured to display a full self accounting even when the product number limit is exceeded. When the terminal 3 is placed on the accounting reader / writer 4, information indicating that the impossible condition is satisfied is transmitted from the portable terminal 3 to the accounting device 5, and the accounting device 5 warns the store clerk. Also good. As a warning method for the clerk, any method may be adopted, and a warning sound may be generated or an e-mail may be transmitted to a portable terminal possessed by the clerk.

  As described above, in the measure based on the member rank, the control unit 31 (an example of “member rank acquisition unit”, “”) of the portable terminal 3 sets the member rank in which the higher rank is specified for the user with higher reliability to the portable ID (“ The member rank stored in association with the mobile ID is acquired from the user DB 122 (an example of “member rank storage means”) of the storage unit 12 that stores the information in association with the “user ID used for user identification”. When the acquired member rank is C rank (an example of “predetermined rank”) or less, the display is controlled so that the “full self” area 563 cannot be selected on the accounting screen 560 (“accounting without checking by the clerk” is possible) An example of “control to make full self-accounting impossible”). As a result, a user with low reliability (that is, a user of rank C or lower) cannot perform full self-accounting, so that the possibility of fraud in full self-accounting can be reduced. In the present embodiment, the user DB 122 (an example of “member rank storage means for storing the member rank in association with the user ID used for identifying the user”) is provided in the shopping server 1, but the member is included in the other storage device. A database that stores the rank in association with the mobile ID may be provided, and the control unit 31 of the mobile terminal 3 may appropriately access the database and refer to the member U's member rank.

[7.2. Measures by user / mobile terminal authentication]
The second measure against fraudulent accounting is to introduce a user / mobile terminal authentication system. The user / mobile terminal authentication system is a system that authenticates the user and the mobile terminal 3 (user / mobile terminal authentication) before the user U uses the shopping system S by using the shopping app. In the above-described embodiment, the mobile ID is used as the ID for identifying the user U. However, when the user / mobile terminal authentication system is described below, the member ID is used as the ID for identifying the user U. The mobile ID is used as an ID for identifying the mobile terminal 3.

  First, the outline of the user / mobile terminal authentication system SB will be described with reference to FIG. A user U who wishes to use a shopping application downloads a shopping application from a predetermined application server or the like in advance to the portable terminal 3 and installs it, and then applies for registration using the registration terminal 7 installed in the store ST. . First, the user U places the portable terminal 3 on the registration reader / writer 6 and inputs user information including an address and a name to the registration terminal 7. When the input is completed, the registration terminal 7 sends the input address and name and the mobile ID obtained from the mobile terminal 3 via the registration reader / writer 6 to the authentication server 8 to request a new member registration. . Further, the registration terminal 7 transmits the mobile ID transmitted to the authentication server 8 and the member ID returned from the authentication server 8 to the mobile terminal 3 and stores them together with the shopping application.

  The authentication server 8 requested to register a new member first generates a new member ID. The newly generated member ID is returned to the registration terminal 7. Then, an authentication key K1 is generated by a predetermined authentication key generation method based on the member ID, the portable ID received from the registration terminal 7, and the authentication character string, and stored in association with the member ID. The authentication character string can be generated according to a predetermined character string generation rule. In the present embodiment, the authentication server 8 generates the authentication character string. However, a character string generation device other than the authentication server 8 may generate the authentication character string. The authentication server 8 encodes the authentication character string to generate a two-dimensional code TC. The generated two-dimensional code TC is an example of paper (“recording medium”, “printed medium”) with a printer (not shown). In this embodiment, the printed two-dimensional code TC is printed on paper. The paper (referred to as “token T”) is delivered to the address / name received from the registration terminal 7 by the delivery company.

  The user U photographs the two-dimensional code TC printed on the token T delivered by the delivery company with the portable terminal 3 placed on the registration reader / writer 6 at the store ST. The portable terminal 3 decodes the photographed two-dimensional code TC according to a two-dimensional code decoding program installed in advance, and acquires a base character string. The portable terminal 3 transmits the acquired character string to the authentication server 8 together with the previously stored portable ID and member ID.

  On the other hand, the authentication server 8 generates an authentication key K2 from the character string received from the mobile terminal 3, the mobile ID, and the member ID by a predetermined authentication key generation method. Then, it collates with the authentication key K1 previously stored in association with the member ID, and if they match, a permission signal permitting the use of the shopping application is transmitted to the portable terminal 3. On the other hand, if they do not match, a non-permission signal indicating that the authentication has not been completed normally is transmitted to the mobile terminal 3.

  When the portable terminal 3 receives the permission signal, it turns on the authentication flag managed for the shopping application. Note that the shopping application can be used only when the authentication flag is on, and is off when installed. In other words, the user U cannot use the shopping system S using the shopping application without going through a predetermined registration procedure.

[7.2.3. Configuration of mobile terminal 3]
When the user / mobile terminal authentication system SB is introduced, the storage unit 32 of the mobile terminal 3 stores a member ID, a mobile ID, and an authentication flag used in the shopping application. The member ID is generated by the authentication server 8 and stored from the registration terminal 7. As the mobile ID, the individual identification number of the mobile terminal 3, the ID of an IC card (IC chip) built in the mobile terminal 3, the telephone number of the mobile terminal 3, etc. can be used. It is assumed that the shopping application pre-defines it. The control unit 31 (shopping application) may generate a mobile ID (for example, generate a random character string and use it as a mobile ID). The authentication flag is a flag indicating whether or not the use of the shopping application is permitted by the authentication server 8, and indicates that the shopping application is installed in the mobile terminal 3 until the above-described permission signal is received. Yes.

  When the control unit 31 detects that the mobile terminal 3 is placed on the registration reader / writer 6 in a state where the shopping application is installed, the control unit 31 transmits the mobile ID to the registration terminal 7. . It also manages the member ID, mobile ID and authentication flag used in the shopping app. In addition, a function for decoding a two-dimensional code included in an image is realized.

[7.2.4. Configuration of Registration Reader / Writer 6 and Registration Terminal 7]
Next, the configuration of the registration reader / writer 6 and the registration terminal 7 will be described with reference to FIG.

  As illustrated in FIG. 23, the registration reader / writer 6 includes a control unit 61, a storage unit 62, a communication unit 63, an RF communication unit 64, and an antenna 65. Further, the registration reader / writer 6 is provided with a mounting table for mounting the mobile terminal 3, and the non-contact IC chip of the mobile terminal 3 is mounted while the mobile terminal 3 is mounted on the mounting table. 36 and the registration reader / writer 6 can exchange data with each other. The configuration and functions of the registration reader / writer 6 are the same as those of the reader / writer 2 and the accounting reader / writer 4 when entering a store, and therefore the description thereof is omitted.

  On the other hand, the registration terminal 7 is a terminal used when the user U makes a registration application for using the shopping system S using the shopping application on the mobile terminal 3. The registration terminal 7 is composed of, for example, a personal computer or the like, and includes a control unit 71, a storage unit 72, a communication unit 73, a display unit 74, and an operation unit 75. The communication unit 73 controls communication with the registration reader / writer 6 and the authentication server 8 connected via the network NW.

  The storage unit 72 includes, for example, a hard disk drive and stores various programs such as an operating system and a registration application (hereinafter referred to as “registration application”) program. Note that the various programs may be acquired from, for example, another server device or the like via the network NW, or may be recorded on a recording medium and read via the drive device.

  The display unit 74 includes a display device such as a liquid crystal display. The operation unit 75 includes a keyboard, a mouse, and the like. When the user U performs membership registration, user information such as an address and a name can be input.

  The control unit 71 includes a CPU, ROM, RAM, and the like. The CPU implements various functions by reading and executing various programs stored in the ROM and the storage unit 72. Specifically, the control unit 71 realizes a function of inquiring the authentication server 8 for the member ID, a function of transmitting the input user information, the member ID, and the mobile ID to the authentication server 8.

  If there is an existing member service (for example, a point service) operated at the store ST and the user U is registered for the member service, information registered for using the member service is registered. (User information such as membership number, address, name, etc.) can also be used for registration of the shopping application. For example, a member number for using the member service may be used as a member ID for using the shopping application. Further, even if a registration number of the shopping application is requested by having the registration terminal 7 input the member number and transmitting the input member number to the authentication server 8 together with the user information including the mobile ID, address and name. Good. Furthermore, user information or the like that has already been registered by the registration terminal 7 may be acquired from a server or the like that provides a member service and used.

[7.2.5. Configuration of authentication server 8]
Next, the configuration of the authentication server 8 will be described with reference to FIG.
explain.

  As shown in FIG. 24, the authentication server 8 includes a control unit 81, a storage unit 82, and a communication unit 83. The communication unit 83 controls communication with the registration terminal 7 and the mobile terminal 3.

  The storage unit 82 includes, for example, a hard disk drive, and stores various programs such as an operating system and an authentication application program (hereinafter referred to as “authentication application”). Note that the various programs may be acquired from, for example, another server device or the like via the network NW, or may be recorded on a recording medium and read via the drive device.

  The storage unit 82 is provided with an authentication DB 821. As shown in FIG. 25, a member ID, a mobile ID, an address, a name, and an authentication key are registered in the authentication DB 821. The member ID, mobile ID, address, and name are registered when these pieces of information are received from the registration terminal 7. As the authentication key, the authentication key K generated when the information is received from the registration terminal 7 is registered.

  The control unit 81 includes a CPU, ROM, RAM, and the like. The CPU implements various functions by reading and executing various programs stored in the ROM and the storage unit 82. Specifically, the control unit 81 has a function of creating a member ID, a function of generating an arbitrary authentication character string generated according to a predetermined character string generation rule, and a mobile ID, a member ID, and a character string by a known method. A function for generating an authentication key K by a predetermined authentication key generation method, a function for generating a two-dimensional code TC from a character string by a known method, a key authentication function for comparing the authentication key K1 and the authentication key K2, and the like are realized.

[7.2.6. User / mobile terminal authentication flow]
Next, the flow of user / mobile terminal authentication will be described with reference to FIG. First, the user U places the mobile terminal 3 on the mounting table of the registration reader / writer 6 connected to the registration terminal 7 (step S71), and inputs user information such as an address and a name to the registration terminal 7 ( Step S72). At this time, when the portable terminal 3 is placed on the registration reader / writer 6, the control unit 71 of the registration terminal 7 displays an input form (not shown) for the user U to input user information. To display.

  When the input of user information by the user U is completed, the control unit 71 of the registration terminal 7 transmits a new member registration request to the authentication server 8 together with the input user information and mobile ID (step S73). On the other hand, the control unit 81 of the authentication server 8 generates a member ID and transmits it to the mobile terminal 3 via the registration terminal 8 (step S74). When receiving the member ID from the authentication server 8 via the registration terminal 8, the control unit 31 of the portable terminal 3 stores it in the storage unit 32 together with the shopping application.

  Moreover, the authentication character string which consists of arbitrary character strings is produced | generated (step S75). Next, the control unit 81 generates an authentication key K1 from the mobile ID received by the process of step S73, the member ID generated by the process of step S74, and the authentication character string generated by the process of step S75 (step S76). At this time, the control unit 81 generates the mobile ID and user information (address, name, etc.) received from the registration terminal 7 by the process of step S73, the member ID generated by the process of step S74, and the process of step S75. The authentication key K1 is registered in the authentication DB 821 in association with each other.

  Moreover, the control part 81 produces | generates the two-dimensional code TC by encoding the authentication character string produced | generated by the process of step S75 (step S77). Next, the control unit 81 generates a token T printed with the two-dimensional code TC (step S78). The token T is a printed matter in which the two-dimensional code TC is printed on a printing medium such as paper, and is generated when the control unit 81 causes a printer (not shown) to print. Next, the token T is put in an envelope and delivered to the address / name included in the user information by a delivery company (preferably a postal business company or a letter service company) designated by the administrator of the authentication server 8 or the like. (Step S79).

  When the user U receives the token T, the user U photographs the two-dimensional code TC printed on the token T with the camera 37 of the portable terminal 3. The control unit 31 of the portable terminal 3 acquires a character string by decoding the two-dimensional code TC included in the photographed image (step S80). Next, the control unit 31 transmits the acquired character string to the authentication server 8 together with the mobile ID and the member ID stored in the storage unit 32 (step S81).

  When receiving the mobile ID, the member ID, and the character string from the mobile terminal 3, the control unit 81 of the authentication server 8 generates the authentication key K2 from the received mobile ID, the member ID, and the character string by the same method as in step S76 ( Step S82). And the control part 81 collates the authentication key K2 produced | generated by the process of step S82 with the authentication key K1 acquired from authentication DB821 based on the portable ID and member ID which were received by the process of step S81 (step S83). . When it is determined that the two authentication keys K match, the control unit 81 transmits a permission signal permitting the use of the shopping application to the mobile terminal 3 that has transmitted the mobile ID, the member ID, and the character string. (Step S84). On the other hand, if it is determined that the two authentication keys K do not match, a non-permission signal indicating that the authentication has not been completed normally is transmitted to the mobile terminal 3.

  On the other hand, when detecting the reception of the permission signal, the control unit 31 of the mobile terminal 3 turns on the authentication flag and displays a screen indicating that the use of the shopping application is permitted. Thereafter, the user U can use the shopping application on the mobile terminal 3. On the other hand, when detecting the reception of the non-permission signal, the control unit 31 displays a screen indicating that the authentication has not been completed and notifies the user U of the screen.

  As described above, the user / portable terminal authentication system SB (an example of the “authentication system”) according to the present embodiment uses the shopping system S with the user U who enjoys the service provided by the shopping system S via the shopping application. This is a system for authenticating a mobile terminal 3 (an example of “mobile terminal device”) used by an authentication server 8 (an example of “authentication server”). The control unit 81 (an example of “acquisition unit” and “token generation unit”) of the authentication server 8 newly sets the member ID of the user U who uses the mobile terminal 3 (an example of “user ID used for user identification”). And generating a mobile ID of the mobile terminal 3 (an example of “terminal ID used for identification of mobile terminal”) and user information including at least an address and a name of the user U, and a predetermined character string A two-dimensional code TC (“code”) obtained by encoding the authentication character string generated according to the generation rule is generated. Further, the authentication DB 821 (an example of “storage means”) in the storage unit 82 is associated with the acquired member ID and mobile ID, and is generated from an authentication character string according to a predetermined authentication key generation rule (“ An example of an “authentication key generated from a character string according to a predetermined authentication key generation rule.” In the present embodiment, the key is generated by a predetermined authentication key generation method based on the mobile ID, member ID, and authentication character string. ) Is memorized. The control unit 31 (an example of “character string acquisition unit” and “transmission unit”) of the portable terminal 3 is a token delivered by the delivery company based on the address and name included in the user information acquired by the authentication server 8. The character string is acquired by decoding the two-dimensional code TC printed (recorded) on T, and the acquired character string, member ID, and mobile ID are transmitted to the authentication server 8. On the other hand, the control unit 81 of the authentication server 8 (an example of “verification unit” and “permission unit”) generates an authentication key K2 generated according to a predetermined authentication key generation rule from the received character string, and the received member ID and mobile ID. The authentication key K1 stored in association with is acquired, the two authentication keys K are collated, and if they match, a permission signal (an example of “permission notification”) is transmitted to the mobile terminal 3.

  Therefore, according to the user / mobile terminal authentication system SB, the character string obtained by decrypting the two-dimensional code TC printed on the token T delivered to the user U and the authentication server 8 generated in advance. Use of the service by the shopping system S is permitted only for the portable terminal 3 that has transmitted the member ID and the same portable ID as the received portable ID. That is, access to the service can be permitted only for the user U who can receive the delivery at the address known on the authentication server 8 side and the portable terminal 3 possessed by the user U. Even if the authentication key K1 or the like stored in the authentication server 8 is stolen, as long as the token T delivered by the delivery company is not stolen or the two-dimensional code TC printed on the token T is stolen, Since the use of the terminal device is not permitted, safety is improved. Furthermore, even if the two-dimensional code TC is stolen, it is difficult for a person who has seen it to obtain a character string from the two-dimensional code TC at a glance, so that safety is improved. Furthermore, for example, when the two-dimensional code TC is input as image data, the mobile terminal 3 can easily obtain a character string to be transmitted to the authentication server 8 simply by decoding the two-dimensional code TC. .

  In the present embodiment, authentication is performed by verifying the authentication keys K generated before and after delivery, but it is also possible to use a configuration in which character strings are verified without using the authentication key K. Specifically, an authentication character string is registered in the authentication DB 821 of the authentication server 8 instead of the authentication key K1, and collated with the character string transmitted from the portable terminal 3 in step S80 of FIG. However, in this case, when a third party other than the user U illegally accesses the authentication DB 821 and steals the member ID, mobile ID, and authentication character string, the stolen member ID, mobile ID, and authentication character string are stored in the mobile terminal. Even if it is a case where it transmits from terminals other than 3, there exists a possibility that a permission signal may be transmitted to the said terminal. On the other hand, there is also an advantage that the processing load for generating the authentication key K1 can be reduced.

  In this embodiment, a printed matter on which a two-dimensional code TC obtained by encoding an authentication character string is printed is delivered as a token T. However, a printed matter on which an authentication character string is printed as it is is delivered as a token T. Also good. Moreover, it is good also as delivering what recorded the audio | voice data which reads an authentication character string on CD-R (an example of a "recording medium") as the token T. In any case, the user U needs to manually input a character string into the portable terminal 3, but the processing load for generating the two-dimensional code TC of the authentication server 8 can be reduced. Instead of encoding the authentication character string into the two-dimensional code TC, the authentication character string may be encoded so as to be compatible with other code systems such as a one-dimensional code, and may be printed on a printing medium and delivered.

  In addition, when the shopping application is stored in advance in the storage unit 72 of the registration terminal 7 and the portable terminal 3 is held over the registration reader / writer 6, the shopping application stored in the storage unit 72 is stored in the portable terminal 3. It may be downloaded and installed.

  In addition, for steps S71 to S74 in FIG. 26, a personal computer with a reader / writer function in which a registration application is installed may be used instead of the registration reader / writer 6 and the registration terminal 7. In this case, the user U can perform member registration for using the shopping application at a place other than the store ST.

  In the present embodiment, the authentication server 8 creates the member ID, but the registration terminal 7 or the mobile terminal 3 may generate the member ID. When the control unit 71 of the registration terminal 7 generates, the store ID of the store ST where the registration terminal 7 is installed is included in a predetermined position (predetermined digit) of the member ID, so that the member between the multiple stores Duplicate ID generation can be avoided. In addition, when the control unit 31 of the mobile terminal 3 generates, information included in each mobile terminal 3 such as a telephone number of the mobile terminal 3 is included in a predetermined position (predetermined digit) of the member ID, so Duplicate generation of member IDs between terminals can be avoided.

  In the present embodiment, the authentication key K is generated from the mobile ID, the member ID, and the authentication character string by a predetermined authentication key generation method. However, the authentication key K may be generated based on at least the authentication character string, For example, based on either one of the mobile ID or the member ID, or other information (for example, the store ID of the store ST where the member registration application is made) and the authentication character string, a predetermined authentication key generation method is used. The authentication key K may be generated. Alternatively, the authentication key K may be generated based only on the authentication character string.

  In the present embodiment, the user / mobile terminal authentication system S is applied to a registration application when the user U uses the shopping application on the mobile terminal 3 to newly use the shopping system S. However, a predetermined service is provided to the user. Other applications to be provided (for example, applications that require a high degree of reliability when used) and registration applications when a system is newly used can also be used. The user / mobile terminal authentication system S can also be applied when managing a server device that allows access only from registered terminal devices.
