I agree. Magnetic cards are old hat. Standalone smart card reader/writers can be built very inexpensively (read <$20 in pats) and the ISO7815 cards are about a buck in small quantities with gobs of room for data. As well, the cards can be made secure, reducing the need for PIC based algorithms.

Have you considered a system with PIC1684-based smartcards?
