Magnetic Ink Character Recognition (MICR) is a technology used to recognize characters printed with magnetic ink. The characters are usually printed in a unique font called E-13B, which is easily recognizable by MICR devices.
MICR technology is commonly used on bank cheques, where it is used to read the MICR line at the bottom of the cheque. This line contains important information such as the bank routing number, account number, and cheque number. MICR technology allows banks to quickly and accurately process cheques, reducing the risk of errors and fraud.
While MICR technology could potentially be used in other applications, such as large data capturing machines, it is not commonly used in these contexts. MICR technology is not used in voice recognition devices or mobile devices, as these technologies rely on different methods of input and output.
