Extensions for Financial Services (XFS) interface specification Release 3.20 - Part 63: Identification Card Device Class Interface Migration from Version 3.10 (CWA 15748) to Version 3.20 (this CWA) Programmer's Reference

Scope

This section 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)
Some motor driven card reader/writers have parking stations inside and can place identification cards there. Once a card is in its parking station another card can be accepted by the card reader. Cards may only be moved out of a parking station if there is no other card present in the media read/write position, the chip I/O position, the transport, or the entry/exit slot.
