ISO/IEC 24727-3:2008

ISO/IEC 24727 is a set of programming interfaces for interactions between integrated circuit cards (ICCs) and external applications to include generic services for multi-sector use. The organization and the operation of the ICC conform to ISO/IEC 7816-4.

ISO/IEC 24727 is relevant to ICC applications desiring interoperability among diverse application domains.

ISO/IEC 24727-3:2008 defines services as representations of action requests and action responses to be supported at the client-application service interface. The services are described in a programming language independent way.

ISO/IEC 24727-3:2008 is the application interface of the Open Systems Interconnection Reference Model defined in ISO/IEC 7498-1. It provides a high-level interface for a client-application making use of information storage and processing operations of a card-application as viewed on the generic card interface.

ISO/IEC 24727-3:2008 does not mandate a specific implementation methodology for this interface.
