OCR vs. MICR: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on February 21, 2024
OCR (Optical Character Recognition) converts different types of documents into editable and searchable data. MICR (Magnetic Ink Character Recognition) is a technology used to verify the legitimacy and originality of paper documents, especially checks.

Key Differences

OCR technology is designed to digitally recognize and interpret printed or handwritten text characters within digital images of physical documents. MICR, on the other hand, specifically reads characters printed in magnetic ink, primarily used in banking for check processing.
OCR can be applied to a wide range of documents, from scanned paper documents to images captured by digital cameras. MICR, however, is more specialized, focusing on the recognition of a specific set of characters and symbols printed in a unique magnetic ink, typically on bank checks.
The versatility of OCR makes it useful in numerous applications like digitizing printed texts, automating data entry processes, and even in license plate recognition. MICR's use is mainly in the banking sector, where it enhances the security and efficiency of check processing and validation.
OCR software can vary in complexity, from simple text recognition in a single language to complex systems that can recognize handwriting or multiple languages. MICR systems, in contrast, are designed to read only the MICR font, which contains numbers and a limited set of symbols.
OCR has evolved with advancements in machine learning and AI, allowing for more accurate and versatile text recognition, MICR has remained relatively consistent in its design and application, focusing on secure and reliable processing of financial documents.
