    Hello,

    I was wondering if anyone could help.
    We have written an android app that can read NFC fobs.
    We are currently testing with a Mifare Classic 1K Configuration fob.

    When the device reads the fob it returns the value 04c55ffa. The number on the fob is 4200580356.
    Is there a way to convert the first number to get the second? Preferably in SQL.

    Many Thanks,
    Tom
