    Hello,

    which Application Note did you use ?
    Do you develop for iOS or macOS ?
    Where does this 101 error appear ?

    Please try to be as precise as possible to enhance your chances to have a good answer :-)

    Answer to myself, with the very good help from NXP support team: my card was initialized in single DES, and I computed the session as if it was not.

    The good computation is explained at the bottom of 6.2 p. 45 or the doc AN0945:
    - session key = RndA(byte0-byte3) + RndB(byte0-byte3)
    and, in my case, not RndA(byte0-byte3) + RndB(byte0-byte3) + RndA(byte4-byte7) + RndB(byte4-byte7)

    That's all, and simple.

    Sorry, mistake writing the title : the error is 1E as you can read down the post, not E1 (but the question is still the same).
