Prior to PC/SC

No standardization on reader communication protocols

No standardization on application APIs

Application locked to vendor-specific drivers & readers

Expensive readers, few smart card applications

PC/SC Smart Card Readers

Workgroup formed in 1996 Microsoft, with major card and computer vendors as founding members

Addresses need for PC – Smart Card Reader interoperability

Can have multiple readers and different interfaces (eg. PCMCIA, RS232, USB, etc.)

Applications and vendors are neutral

Defines how a smart card reader interfaces to the OS & how an application interfaces with the OS to interact with the smart card reader and smart card

The application is not locked to any vendor’s reader

Does not define the smart card reader communication protocol

Reader’s vendor must supply the PC/SC driver
