SCEZ is a library that should make the handling of smart cards (not memory cards) and card readers as simple as possible and be at the same time small and easily portable. Currently supported are Dumb Mouse, CT-API and Towitoko readers and Schlumberger Cryptoflex, Gemplus GPK4000, GSM SIM and Telesec SigG cards. A PKCS#15 implementation is in the design phase. There are ports to PalmOS and MS-Windows available.
