Define the term MICR and explain what it is. Using a suitable example, discuss how does MICR readers work and what is it used for?
MICR, or Magnetic Ink Character Recognition, 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. It allows computer to read account number off printed documents. Its different and unlike with barcodes or other similar technologies, MICR codes can be easily read by humans. MICR characters usually contain iron oxide. They are printed in special typefaces with a magnetic ink or toner and in the form of either and E-13B or CMC-7 Font. Each font series is made up of a series of numbers and symbols specifically designed for readability on check sorting machines which read and extremely high rates of speed. The machine can always determine what each series of number signifies quickly, due to the symbols provide a beginning and end pint for each group of numbers. Line placement, character placement skew and quality are several critical components of printing MICR; the line must be precisely positioned in the MICR Clear Band area. The use of magnetic printing allows the characters to be read reliably even if they have been overprinted or obscured by other marks, such as cancellation stamps and signature. The magnetic scanning of a typical check has a smaller error rate than with optical character recognition systems. As for well printed MICR documents, the “can’t read “rate is usually less than 1% while the misread rate is in the order of 1 per 100,000 characters.
A cheque is a suitable example to discuss how MICR readers work and what it is use for does. When a bank receives a check for payment, is uses an MICR inscriber to print the amount of the check in MICR characters in the lower-right corner. The check then is sorted or routed to the customer’s...
