1.2.3 MICR CHARACTERISTICS
The MICR (Magnetic Ink Character Recognition) device reads characters printed on
checks with magnetic ink. The basic standards for MICR applications are CMC7 and
E13B.
CMC7: This standard uses a coding technique similar to bar codes. In this case the
character consists of seven black bar codes of equal width and spaced by four
narrow gaps and two wide gaps.
E13B: In this case the characters are continuous (not bars) and have a precise form. The
magnetic reader must also interpret the amplitude of the wave form and therefore
not only is variation in time.
