Bluetooth smart card reader

[siddhantmishra1305]

I am working on to create a bluetooth smart card reader (ex: ex: https://www.youtube.com/watch?v=RPm3VPsIfvg ). Since IFDHandler is only for USB based readers it wouldn't detect a smart card over bluetooth.

I need to create a driver that could interface between bluetooth reader and OS.

Any idea how I can proceed with this ? or any other way to achieve this ?

The API is also for serial (or non-USB) readers.

@LudovicRousseau Is it possible to achieve this in macOS ? I was under the impression that Mac OS X 10.10+ ships with a proprietary implementation of the PC/SC layer instead of with PCSC-Lite and it only supports USB.

[LudovicRousseau]

Yes, it is a bit different on macOS.
But is it still possible.

Okay I am new to this so do not have much idea but I was thinking in below direction and got stuck on Step 3.

Step 1. Connect Reader over Multipeer/bluetooth.

Step 2. SCardEstablishContext -> This would provide context

Step3. SCardListReaders -> This would provide list of readers but I guess this would only return readers connected over USB right ?



Since BT reader won’t be part of list, how to connect to the reader and transmit APDU commands ?

I think I might need to add custom implentation for functions SCardListReaders, SCardConnect, SCardTransmit in winscard.c . So I could add code to detect a BT reader and transmit/recieve APDU commands.

Please let me know If I am thinking in the right direction ? Also if you see any better way to achieve this please share your inputs.

Thank you

It does not work like that.

github issue is not the place to discuss. Contact me by email. See https://blog.apdu.fr/articles/about_me/
