    Hi kerry9842,

    as I argue to you on another thread we cannot provide support for the libnfc library.

    Please take in mind the MIFARE DESFire card is a security product and the communication between the card and the reader is normally encrypted. This means that every read or write cycle is a sequence of encrypted commands. The first step is to personalize the card from the factory settings to dedicated keys and format sectors on the card with use this keys. You need a cypher component on the library which do the encrypting of the sequence byte streams.

    Best regards,
