    Hi all,

    We are working with a DESFire EV1 card. We can do an authentication using the ISO 7816-4 INS commands supported by it.
    Below you can see that the authentication (both external and internal) works perfectly.

    The question is, we want to do only an INTERNAL_AUTHENTICATE because we just need to be sure the card is a valid one. How can we do this??

    The problem is when we send only the internal INTERNAL_AUTHENTICATE as described below (without issuing the GET_CHALLENGE and EXTERNAL_AUTHENTICATE) the card responds with the following:

    ONLY INTERNAL_AUTHENTICATE
