This specification describes the functionality of the services provided by the Card Dispenser (CRD) device class under XFS, by defining the service-specific commands that can be issued, using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions.
A Card Dispenser is used to dispense a single card to a consumer from one or more bins. Most card dispensers also have the ability to retain a card to a bin.
XFS 3.40 has been designed to minimize backwards compatibility issues. This document highlights the changes made to the CRD device class between version 3.30 and 3.40, by highlighting the additions and deletions to the text.
