Using PC/SC application
PC/SC Overview
The PC/SC specification describes the minimum functionality required of smart cards, smart
card readers, and PCs to allow interoperability among compliant elements as provided by a
variety of vendors.
The specification as a whole seeks to achieve the following objectives:
• Maintain consistency with existing smart card-related and PC-related standards
while expanding upon them where necessary and practical.
• Enable interoperability among components running on various platforms (platform
neutral).
• Enable applications to take advantage of products and components from multiple
manufacturers (vendor neutral).
• Enable the use of advances in technology without rewriting application-level
software (application neutral).
• Facilitate the development of standards for application-level interfaces to smart card
services in order to enhance the fielding of a broad range of smart card-based
applications in the PC environment.
• Support an environment that encourages the widest possible use of smart cards as
an adjunct to the PC environment.
