Hi Team,

one of my customer using TRF7960.

can we  use  TRF7960 to read/write the DESFire cards?

If Possible request you to arrange the sample firmware code for interfacing DESFire cards using TRF7960.

Thanks and Best Regards,

    Hi Amit,

    Yes, the TRF7960 can be used to read/write DESfire cards, but we do not have example firmware for these specific cards. 

    DESFIRE is based on the ISO14443A standard which is supported by the TRF7960.  Our example firmware operates up to layer 3.  As different cards will have a different implementation of layer 4, this should be implemented in the customers firmware.  DESFIRE is based on 3DES encryption.  See the attached presentation for an overview of ISO 14443A/B and the different layers.  

    Let me know if you have questions. 

    Best Regards,

    Eddie LaCost

    Hi Eddie,

    Thanks for the information.

    Can we share firmware till layer 3 to customer? If yes please mail me the firmware code.

    Let me know also if NDA  required for sharing code with the customer.

    They are using MF3ICD8101 and MF3ICD40 in their application.

    Hi Eddie,

    Thanks for your response.
    The firmware code for DESFire which your have sent contains only to get the UID of DESFire cards.


    Request you to arrange  the code for the actual DESFire authentication process and file creation process and data manipulation commands.

     1. Security related commands
        Authenticate, Change Key Settings, Get Key Settings, Get key version

    2. PICC Level Commands
        Create Application , Delete Application ,Get Applications, Select Application,Format PICC, Get Version

    3. Application Level commands:
        Get file IDs, Get File settings, Change File settings, Create Std data file, Create backup data file,Create value file, Create Linear record file,Create cyclic  Record file, Delete file

    4. Data Manipulation commands
        Read data, Write data, Get Value, credit, debit, limited credit, write record , read record,clear record file,commit transaction, abort transaction.

    With Best Regards,

    Amit,

    These are layer 4 commands.  This needs to be implemented by the customer.  We also have third party consultants who could offer such firmware.  Let me know if your customer is interested in working with a consultant.
