The card seems to tell you that the PIN you entered is incorrect. The encoding doesn't look correct. I suggest BCD encoding, which is something like: 12 34 56 78 or ASCII encoding, which is something like this: 31 32 33 34 35 36 37 38 Maybe if we knew the type of card, someone could provide more speciffic help on this -- Frank Morgner Virtual Smart Card Architecture http://vsmartcard.sourceforge.net OpenPACE http://openpace.sourceforge.net IFD Handler for libnfc Devices http://sourceforge.net/projects/ifdnfc
