Abstract
A hand-operated document processor includes a base for receiving a document containing magnetic ink character data to be read and recognized, and a manually operated moving magnetic ink character recognition (MICR) subsystem. The subsystem includes a MICR read head. Movement of the subsystem causes the MICR read head to pass over the magnetic ink character data on the document. The base further includes a series of embedded markers that may be magnetic or optical. A speed sensing sensor is positioned such that the speed sensing sensor passes over the series of markers as the MICR read head passes over the magnetic ink character data on the document. MICR reading and recognition logic receives the signal from the MICR read head and the signal from the speed sensing sensor to provide position feedback information to the logic for use during character data recognition.
