Why is Difference Between NBFC and MFI

MICR and OCR: MICR and OCR technologies are becoming more commonly employed by businesses today. MICR stands for Magnetic Ink Character Recognition while OCR refers to Optical Character Recognition; both technologies share similar functions but this article will explore their differences and specific applications despite sharing similar traits.

Meaning of  OCR

Figure-no-1: OCR
  • OCR (Optical Character Recognition), is a scanner that scans pages containing text. OCR software then converts this image of text into editable ASCII text format for use by word processing applications to make changes. OCR works by extracting grid dots from images of text and converting this array of dots to equivalent ASCII texts that a computer can render as letters, numbers, or special symbols.
  • OCR software can recognize all sorts of printed characters. Traditional OCR was less successful at scanning script font and handwriting, but with newer smart systems’ greater accuracy, they can recognize a wider variety of fonts and even produce output in a format similar to what they scanned in.
  • OCR accuracy depends heavily on the quality of the scanner used, with 1,200 dots/inch texts taking longer to scan but providing higher accuracy than 72 dots/inch text documents.

Meaning of MICR

  • MICR (Magnetic Ink Character Recognition) is similar to character scanning but utilizes magnetic ink instead. To use MICR scanning technology, documents are placed under a scanner that converts magnetic information into text characters – this technology is frequently employed by banking systems for quickly processing large volumes of cheques.
  • Banks using MICR print the bank code, cheque number, and account number on cheques with special magnetic ink containing iron oxide particles that allow characters to be read easily even when there are overwriting or marks on them. Magnetic printing makes these characters easily legible.
  • MICR applications typically utilize characters from fonts such as E-138 or CMC-7; in India, Canada, and the UK however, E-13B characters are used at the bottom of cheques to print MICR characters.

History of MICR

The development of Magnetic Ink Character Recognition, commonly known as MICR, began around the middle of the 20th century. Implementation in banking sectors worldwide soon followed suit.
