Authenticate Mifare DESFire with SAM AV2

Forum / MIFARE SmartCard IC`s / Authenticate Mifare DESFire with SAM AV2

  • 21. November 2019 at 11:40
    I am currently authenticating the Mifare Desfire with SAM AV2. I am referring to the document AN1826 - Section 2.2.1. However, after I received the RndB, I send the SAM_AuthenticatePICC command with the keyN, keyVer and RndB, but it always respond me with 6985. I am not sure what's the description of the response code. The description is as below:
    - conditions of use not satisfied (Key entry cannot be used for authentication; MIFARE SAM AV2 needs to be unlocked with Key entry 00h first; KUC limit reached)

    I really need help in this issue. Thank you so much.

    Hi Veng Sie,

    I have answered to your question in a email to you. I cannot explain details of NDA classified material on a public server.

    Hello TapLinx team,

    Sorry, I couldn't open another topic in forum.

    I have the same issue with Mifare Plus X card during the authentication in Mifare SAM AV2. I got 6985 response after SAM_AuthenticateMFP.
    Please, can you help me?

    Thank you in advance!
