OCR or optical character reader is a device that recognizes characters from either printed or hand-written documents, then digitizes them into text format. Questions of the nature of 'what is optical character reader' pertain more to the technology or device used to identify characters. It has a lot to do with optical character recognition, a technique that assists in understanding characters that have been digitized through an image or scanning of documents. Organizations may use optical character recognition machines to process their invoices, receipts, forms, identity documents, reports, and any other document. Rather than typing the data by hand, an optical character reader captures the text in the document and enables one to edit, search, or manipulate it further. Optical character readers currently identify various fonts, numbers, symbols, and document formats.
