    Hi,
    I can correctly from my App work with DESFire EV1 and EV2 - Taplinx 1.8.
    It works fine with Android 6 and Android 9, but I have a problem with EV2 and Android 4.4
    When I try to do a simple request :

    `
    val tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG)
    this.cardType = it.getCardType(tag)
    `

    I get a NxpNfcLibException with the following message on the getCardType call:
    "Unknown Error SW2 = 11"

    On this same device with the same app and EV1 tag, it works fine, the problem only occurs with EV2 tags.

    The tagInfo export of this tag is attached with this topic.

    Thanks for your help
