The idea behind PC/SC it to have a unifom interface that is _NOT_ dependant of a particular reader manufacturer. If you want to can compare the smart card communication stack with the network communication stack. You need a driver for your Ethernet card. This driver will provide a uniform API to the kernel. This is the equivalent of the smart card reader driver. Then the kernel provides a higher level API (IP, TCP). This is equivalent to what PC/SC provides. The USB community is working on Chip/Smart Card Interface Devices (CCID). This defines a common protocol (and so a common driver) for all USB CCID compliant smart card resaders. Bye, PS: it would be nice if you could edit you mail and remove the unused parts (nearly all the lines you quoted). -- Dr. Ludovic Rousseau [EMAIL PROTECTED] -- Normaliser Unix c'est comme pasteuriser le Camembert, L.R. -- *************************************************************** Unix Smart Card Developers - M.U.S.C.L.E.
