Magnetic Ink Character Recognition is a string of characters in the lower left corner of a personal check, including the account number, routing, and check numbers.
MICR numbers are intended to be read by both individuals and sorting equipment.
They cannot be faked or copied, thanks to the use of magnetic ink and unique fonts.
The advantages of the technology include increased protection against fraud and mechanization of check processing.
MICR was developed in the late 1950s and is currently used throughout the world.
