What Is MICR Check Printing

This article will cover the history of the MICR line and the MICR technology associated with the way the indication is read and recognized, including a glossary of most terms found in the MICR industry. The article includes: The introduction of the MICR font MICR Readers MICR Waveform Theory What Affects the MICR Signal Level? Magnetic Ink Character Recognition (MICR) originated to make use of the advantages of computer technology in the bank industry. To the use of a MICR line Prior, check sorting by account number was a manual process. Two systems were previously used to handle the large numbers of checks prepared in the banking industry: Sort-A-Matic and Top Tab Key Sort.

The Sort-A-Matic system included 100 metallic or leather dividers numbered 00 through 99. Each check was positioned in the related divider by the first two amounts of the account. The sorting process was repeated for another two digits of the account number then, etc. When the procedure was complete, the bank checks were grouped by accounts number. Under the Top Tab Key Sort system, small openings punched at the top of the investigations indicated the digits.

A metallic “key” was put through the holes to separate all the investigations with the same value in the first digit, and this step was repeated for each digit until all the inspections were sorted. Both of these systems worked well, however they were time-consuming. With all the advancement of the computer and its motion from the lab in to the business world, a sorting and matching task seemed ideal.

Stanford University and Bank of America were the first to successfully use computers to kind and match bank checks. They developed what is known as MICR now . The Development of the MICR FontThe MICR font was developed by Stanford University in conjunction with Bank of America and approved by the American Banking Association. The font is recognized as the E-13B font.

E-13B has a total of 14 people: ten specially designed figures (0 through 9) and four special icons (Transit, Amount, On-Us, and Dash). The letter E shows the fifth version considered. The letter B indicates the next revision of this version. The real quantity 13 is derived from the 0. 013-inch module construction used for stroke and character width.

This means that character widths, both horizontal and vertical, are in multiples of 0.013 ins which range from 0.052 to 0.091. The significance of this will be explained more thoroughly later in this article. MICR ReadersThree types of machines are used to read MICR characters. Both that browse the heroes magnetically are known as MICR visitors.

The third machine is an Optical Character Recognition (OCR) audience. E-13B characters are imprinted with toner containing iron oxide, which is with the capacity of being magnetized. MICR readers transport the assessments filled with the E-13B magnetic individuals past a magnet, magnetizing the iron oxide contaminants thereby. The magnetized individuals pass under a magnetic read mind then.
