    I have a smart card that contains a Mifare Desfire EV1 contactless chip, and I am trying to send an authentication request with masterkey to the contactless part (Mifare Desfire EV1), so I am sending this command :

    -- Auth Req with Master key
    >>> cmd = 90 AA 00 00 01 00 00
    <<< data =
    <<< sw = 68 84
    I don't know why I am getting this error code, it seems that the command was send to contat ship ?

    Can you help me please to figure out what's the problem ? is there any step before to "activate" to contactless part ?

    BtW : I tried with those readers : Omnikey5321v2 and ACR122U-A9

    Thank you!

    Hi Zero,

    We cannot answer this question on a public server, sorry. But you can request a datasheet for the MIFARE DESFire EV1. Please take in mind, only companies which legal business address can obtain this material from NXP.
