How does the MICR work?
Each check is printed with a series of characters on the bottom of the document. The MICR read head is a device built into the scanner designed to read the magnetic signal emitted by the MICR ink characters on the check. Each character produces a unique waveform which is read and translated by the MICR read head.
Many of you would have seen the magnetic inks bar codes printed on the bottom of your bank's cheque leaves. These bar codes are known as MICR code, an abbreviation for 'Magnetic Ink Character Recognition'. Actually, the MICR is the name given to the technology used in printing the code.
- MICR is an abbreviation for “Magnetic Ink Character Recognition”. The MICR code is a 9 digit code, which is printed at the bottom of a cheque. A MICR code is unique to each bank branch. Thus, a MICR code can be used to uniquely identify any bank branch.
- CTS is based on a cheque truncation or online image-based cheque clearing system where cheque images and magnetic ink character recognition (MICR) data are captured at the collecting bank branch and transmitted electronically.
