Magnetic Ink Character Recognition, or MICR, is a character-recognition technology used primarily by the banking industry to facilitate the processing of cheques and makes up the routing number and account number at the bottom of a cheque.
The technology allows computers to read the information (such as account numbers) off printed documents. Unlike barcodes or similar technologies, however, MICR codes can be easily read by humans.
MICR characters are printed in special typefaces with magnetic ink or toner, usually containing iron oxide.
