This specification describes the functionality of an XFS compliant Cash Dispenser Module (CDM) Service Provider. It defines the service-specific commands that can be issued to the Service Provider using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions. Persistent values are maintained through power failures, open sessions, close session and system resets. This specification covers the dispensing of items. An “item” is defined as any media that can be dispensed and includes coupons, documents, bills and coins. However, if coins and bills are both to be dispensed separate Service Providers must be implemented for each. All currency parameters in this specification are expressed as a quantity of minimum dispense units, as defined in the description of the WFS_INF_CDM_CURRENCY_EXP command. There are two types of CDM: Self-Service CDM and Teller CDM. A Self-Service CDM operates in an automated environment, while a Teller CDM has an operator present. The functionality provided by the following commands is only applicable to a Teller CDM: WFS_CMD_CDM_SET_TELLER_INFO WFS_INF_CDM_TELLER_INFO It is possible for the CDM to be part of a compound device with the Cash-In Module (CIM). This CIM\CDM combination is referred to throughout this specification as a “Cash Recycler”. For details of the CIM interface see [Ref. 3]. If the device is a Cash Recycler then, if cash unit exchanges are required on both interfaces, the exchanges cannot be performed concurrently. An exchange on one interface must be complete (the WFS_CMD_CDM_END_EXCHANGE must have completed) before an exchange can start on the other interface. The WFS_ERR_CDM_EXCHANGEACTIVE error code will be returned if the correct sequence is not adhered to. The CIM interface can be used for all exchange operations on recycle devices, and the CIM interface should be used if the device has recycle units of multiple currencies and/or denominations (including multiple note identifiers associated with the same denomination).
