    Hello,
    Thanks again for your answer.
    I'm still searching for solution for this timeout problem in the android documentation and found this :
    http://developer.android.com/reference/android/nfc/NfcAdapter.html#EXTRA_READER_PRESENCE_CHECK_DELAY
    Could it be possible to avoid this timeout problem by using reader mode ?

    Regards,
    Christophe

    Hello,
    Thanks for your answer,
    I already tough about implementing the authentication process in the reader, but my problem is that I need the key on the client app in order to build the response.
    Our application has to work on any android phone, so I it is not possible (and secure) because I should transfer the password in a request from the server.
    It is also not possible to store the passwords on the device, as the application should work on any NFC compatible phone.
    I suppose the mifare authentication won't fit the requirements of our application.

    Do you have another tag that could fit with our requirements?
    We need to be able to authenticate a tag with an android app, by exchanging challenges with a distant server.

    Regards,
    Christophe
