magnetic ink
Noun: - A special type of ink that contains tiny particles of a magnetic material. The presence of these particles can be detected and read by electronic sensors or readers designed to recognize magnetic signals.
This term is used specifically in contexts involving document processing, security, and automated reading systems. It describes the physical substance (the ink) itself. - Primary Use: To refer to the ink used for printing characters, such as the numbers at the bottom of bank checks, which can be read by Magnetic Ink Character Recognition (MICR) devices.
- The bank uses magnetic ink to print the account and routing numbers on checks so they can be processed automatically.
- Forgery is more difficult because the official documents are printed with magnetic ink.
- The machine failed to read the check because the magnetic ink was faded.
- Technical Context: In computing and data capture, "magnetic ink" is integral to MICR technology, which is known for its high reliability and speed in processing financial documents.
- Magnetic Ink Character Recognition (MICR): (Noun) The technology that uses magnetic ink to enable the automatic reading of printed information.
- MICR toner: (Noun) A specific type of toner containing magnetic particles, used in some laser printers for check printing.
- MICR ink: This is a direct synonym, as it specifies the ink's purpose for MICR systems.
This term has a very specific, technical meaning. It does not refer to ink that is simply attracted to a magnet in a general sense, but rather to a formulated substance used for machine-readable encoding.
