Magnetic Ink Character Recognition

MICR

(Magnetic Ink Character Recognition) The machine recognition of numeric data printed with magnetically charged ink. It is used on bank checks and deposit slips. MICR readers detect the characters and convert them into digital data. Although optical methods (OCR) became as sophisticated as the early MICR technology, magnetic ink is still used. It serves as a deterrent to fraud, because a photocopied check will not be printed with magnetic ink.

MICR Font

The E13B standard font is used for MICR digits and symbols on bank checks and deposit slips. There are only 14 characters in the font.
