2. MICR Overview

MICR stands for Magnetic Ink Character Recognition. All MICR documents have a MICR line with numbers and symbols printed in a MICR font with magnetically chargeable toner. Each character of the MICR font has a unique waveform when sensed magnetically.

Financial institutions and the Federal Reserve use the MICR line to identify and sort checks. The high-speed automated processing of checks and other financial documents depends on the accuracy and the integrity of the data printed in the MICR line. Your new Source Technologies Secure MICR Printer is specifically designed to produce high quality MICR documents.

The Check Processing System

As a MICR document travels through the check clearing system it is processed an average of almost seven times by high speed reader/sorter machines. Some checks are read up to 30 times or more by these machines. Reader/sorter machines charge the toner in the MICR line and then read the line with a magnetically sensitive reader.

The MICR line contains numbers and symbols to indicate the check serial number, the routing number of the drawee institution and the makers’ account number. The institution of first deposit encodes the check amount in the MICR line to be read by the reader/sorter equipment. Checks travel through reader/sorters at up to 20 miles-per-hour (2,400 documents per minute) with each MICR line read in three hundredths of a second.

MICR Printing Today

Congress established the Federal Reserve System (FRS) in 1913. Today most commercial banks in the United States belong to the FRS. Many other depository institutions provide banking and checking account services to the public. These other institutions, such as some credit unions, savings and loan associations and non-member banks, are not formally part of the FRS. However, they have access to the payment services it provides and are subject to many of the FRS regulations.

In 1958, because of the explosive growth of check usage, the American Bankers Association selected the E-13B MICR font and the MICR system as the technology for high-speed check processing. Today, check standards are determined by the American National Standards Institute (ANSI) Accredited Standards Committee (ASC) X9B of which Source Technologies is a voting member.
