Hybrid magnetic and optical reader sorters
Hybrid reader sorters use two read technologies:
•
Magnetic waveform recognition
•
Optical character recognition
Compared to other types, hybrid reader sorters have very high
accuracy rates, because they interpret and compare the results
produced by the magnetic waveform recognition and the optical
character recognition. If a character cannot be interpreted by
MICR waveform analysis, the system takes the results of the
optical recognition. In diagnostic situations, understanding the
recognition mode is important.
Another form of hybrid equipment, used primarily in lock box and
remittance processing, uses optical and magnetic recognition in
a fundamentally different way that can cause problems with
MICR documents. These reader sorters process an OCR printed
turnaround document, followed by a MICR printed check. They
identify a check by the presence of magnetic ink, then switch to a
MICR font recognition system. If the turnaround document is
printed with an OCR font but uses MICR ink, it may be
misidentified and rejected, although the OCR font is properly
printed.
Processing speeds
Reader sorters are available in a variety of sizes and processing
speeds. The smallest can fit on a desk top; the largest may be
the size of a mainframe computer. Performance may be
categorized as low, medium, or high speed.
The speeds may be defined as follows, based on the speed of
handling a 6 inch/152 mm long document:
Low speed: Process 100 to 750 documents per minute. These
machines are usually found in small banks or are used for
handling small volumes of checks. They use waveform
recognition.
NOTE: Proofing devices also process documents at these
speeds. Although these devices can operate in reader sorter
mode, they may not have automatic document handlers and
require manual hand feeding.
