Friends,
    I am dealing with PN531 IC for NFC interfaced with lpc1769.
at this condition all operation for MiFARE card(4 byte UID) can be performed successfully.
now I have Mifare Classic 1K card with 7 BYTE UID. Right now I am able to read UID from the Card. BUT can't authenticate to it which in turn dont let me read or write to memory blocks of card.
    HOW CAN I GET AUTHENTICATED WITH THOSE CARDS????????


plz help
