Extensions for Financial Services (XFS) interface specification Release 3.50 - Part 4: Identification Card Device Class Interface - Programmer's Reference

This CWA describes the functions provided by a generic identification card reader/writer service (IDC). These descriptions include definitions of the service-specific commands that can be issued, using the WFSAsyncExecute, WFSExecute, WFSGetInfo and WFSAsyncGetInfo functions. This service allows for the operation of the following categories of units: • motor driven card reader/writer • pull through card reader (writing facilities only partially included) • dip reader • contactless chip card readers • permanent chip card readers (each chip is accessed through a unique logical service)
