CWA 16926-63:2015

This document describes the migration that is necessary from Version 3.20 (CWA 16374) to Version 3.30 (this CWA).
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.
