Magnetic ink character recognition (MICR) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents. The MICR encoding, called the MICR line, is at the bottom of cheques and other vouchers and typically includes the document-type indicator, bank code, bank account number, cheque number, cheque amount, and a control indicator. The technology allows MICR readers to scan and read the information directly into a data-collection device. Unlike barcodes and similar technologies, MICR characters can be read easily by humans. The MICR E-13B font has been adopted as the international standard in ISO 1004:1995,[1] but the CMC-7 font is widely used in Europe.
History
Before the mid-1940s, cheques were processed manually using either the Sort-A-Matic or Top Tab Key method. The processing and clearance of cheques was very time consuming and was a significant cost in cheque clearance and bank operations. As the number of cheques increased, ways were sought for automating the process. Standards were developed to ensure uniformity in financial institutions. By the mid-1950s, the Stanford Research Institute and General Electric Computer Laboratory had developed the first automated system to process cheques using MICR.[3] The same team also developed the E13B MICR font. "E" refers to the font being the fifth considered, and "B" to the fact that it was the second version. The "13" refers to the 0.013 inch character grid.[4]
In 1958, the American Bankers Association (ABA) adopted E13B font as the MICR standard for negotiable documents in the United States. By the end of 1959, the first cheques had been printed using MICR. The ABA adopted MICR as its standard because machines could read MICR
