Mifare DESfire EV2 2k - error in step 2 - authenticate #131
Comments
Hi, I'm also new to the NFC, but I've noticed a method Line 342 in 8f47cf9
Reader , which takes the key you pass and transmits it to load the keys to the NFC reader memory.
I am not sure, but probably you also need to have your key in the reader memory before trying to authenticate. Hope it helps somehow |

Hi all,
I am quite new in the NFC world, so I apologise for any silly things I say, but I have a Mifare DESfire EV2 2k that already has some employee data and I just need to get the ID from it.
I installed this awesome vfc-pcsc package and I tried a Mifare Classic card, which worked fine with the "mifare-classic" example, but when I tried the "mifare-desfire" to read the DESfire EV2 2k, I get this error:
This is the whole return code actually
I read and heard from a person that the card needs to have an original encryption key in order to authenticate.
Is that correct?
In any case, please shed some light on how to read this type of card.
Thank you so much for your help!!!
