Right!

Magnetic ink character recognition (MICR) is a technique used to verify the legality and originality of paper documents, especially checks.

Magnetic ink character recognition (MICR) is a technique used to verify the legality and originality of paper documents, especially checks. Special inks are used to print special quality on original documents. This ink is sensitive to magnetic fields. Information can be encoded in magnetic field characteristics.

The use of magnetic ink character recognition (MICR) can enhance security and minimize losses from some types of crime. If a document is forged, such as a fake check produced using a color photocopier, the magnetic ink lines either do not respond to the magnetic field or produce incorrect codes when inspected using equipment used to recover information in the magnetic field characteristics . If the magnetic ink character recognition card reader shows that the account holder has a record of writing a fake check, his legitimate check may also be rejected.

Retailers generally use magnetic ink character recognition card readers to minimize the losses caused by cheating fraud. Companies and government agencies also use this technology to speed up file classification. ^[1]
