Which data input method do banks mainly use for processing bank cheques?

Banks use MICR (Magnetic Ink Character Recognition) for processing bank cheques. How it works: Cheques are printed with a special ink that contains magnetic particles. An MICR reader scans this magnetic ink to read and process the characters, which typically include the bank routing number, account number, and cheque number. Advantages: This technology enables high-speed, accurate processing and helps prevent fraud, as the magnetic ink is difficult to forge.
