PC/SC (Personal Computer/Smart Card) is the de facto standard interface on desktop systems for communicating with smart cards and readers. On Windows, applications use the native PC/SC API to discover readers, connect to cards, and exchange APDUs. The Java Card Development Kit Windows PC/SC driver presents a standard PC/SC reader interface, integrated with the JCDK Simulator. This allows your existing development ecosystem to interact with the JCDK Simulator as if it were a physical smart card reader.
