Extensions for Financial Services (XFS) interface specification Release 3.30 - Part 18: Item Processing Module Device Class Interface - Programmer's Reference

Publication date:   Apr 18, 2016

Scope

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
