This specification describes the XFS service class for Item Processing Modules (IPM). The specification of this service class includes definitions of the service-specific commands that can be issued, using the WFSAsyncExecute, WFSExecute, WFSGetInfo and WFSAsyncGetInfo functions. This service class is currently defined only for self service devices. In the U.S., checks are always encoded in magnetic ink for reading by Magnetic Ink Character Recognition (MICR), and a single font is always used. In Europe some countries use MICR and some use Optical Character Recognition (OCR) character sets, with different fonts, for their checks. Item Processing Modules accept one or more media items (Checks, Giros, etc) and process these items according to application requirements. The IPM class supports devices that can handle a single item as well as those devices that can handle bunches of items. The following are the three principle device types: - Single Item: can accept and process a single item at a time. - Multi-Item Feed with no stacker (known as an escrow in some environments): can accept a bunch of media from the customer but each item has to be processed fully (i.e. deposited in a bin or returned) before the next item can be processed. - Multi-Item Feed with a stacker: can accept a bunch of media from the customer and all items can be processed together.
