## Standard Documents

Smart cards are defined in ISO 7816 standards. You need to buy those from ISO, but some pages have overviews on what is in those standards.

PC/SC Workgroup defines the PC/SC standard that is used on windows, but thanks to PC/SC-Lite software also on Linux, Mac OS X and BSD. You can download all parts of the specification.

The Multifunctioanal Card Terminal specification suite includes CT-API and it's co-specification CT-BCS. The whole suite is available for download in english and german.
