    Hi Jose,

    Android is using an R(NAK) command of the ISO14443-4 protocol. So nothing that should deselect the card.

    Status 0x1C means Illegal Command. Please, could you check if you are not mixing native commands and wrapped ones or the message is not well formatted ?

    Hi Jim,

    you can check if the card number is the ID reading the first 4 bytes of the block 0 of sector 0 (manufacturer block), see figure 6 of http://www.nxp.com/documents/data_sheet/MF1S50YYX.pdf

    To read this out you can use for example teh NXP Pegoda reader with MIFARE Discovery (see NXP web-site) or any NFC Android phone using the NXP TagInfo application from the Google Play store.

    Regards
    Francesco
