Recognition) The machine recognition of numeric data printed with magnetically charged ink. Pronounced "
mike-er," it is used on bank checks and deposit slips, and MICR readers detect the characters and convert them into digital data. Although optical methods (OCR) became very sophisticated, magnetic ink is still used because it serves as a deterrent to fraud. A photocopied check is not 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.
