Which of following technologies is used in bank cheque processing ? 

The correct answer is Magnetic Ink Character Recognition(MICR).

Key Points

• Magnetic ink character recognition is abbreviated as MICR.
• Magnetic ink character recognition (MICR) is a check identification and processing method.
• The MICR on a check is the string of characters at the bottom left corner of the check.
• The bank routing number, the account number, and the check number are among the three groupings of numbers.
• MICR numbers are intended to be read by both humans and sorting machines.
• Due to the usage of magnetic ink and unique fonts, they can't be faked or replicated.
• Enhanced protection against fraud and mechanisation of check processing are two of the technology's advantages.
• MICR was created in the late 1950s and is currently used all over the world.
