Concept:Optical Character Recognition (OCR) is the technology that reads typed, printed, or handwritten text and converts it into a form the computer can process.
Explanation:OCR scans the document and captures a digital image of the characters present on it.
It then recognises each character using pattern-matching algorithms.
After recognition, the characters are converted into editable digital text that can be stored and processed by the computer.
Therefore, OCR is capable of reading handwritten letters, typeset pages, and printout characters.
In contrast, a barcode reader can only interpret coded barcode lines.
Magnetic Ink Character Recognition (MICR) only reads characters printed in special magnetic ink, such as those on bank cheques.
An Optical Mark Reader (OMR) can only detect marks made in specific positions, like filled ovals on an answer sheet.
None of these other devices can read general written or printed characters.
