OCR<\/p>\n<p>An optical character recognition (OCR) scanner is a device that can read characters directly from an ordinary piece of paper. It does this by using a light source to illuminate the text, and then using a sensor to detect the reflected light. The sensor converts the light into electrical signals, which are then processed by a computer to recognize the characters.<\/p>\n<p>OCR scanners are often used to digitize documents, such as invoices, receipts, and business cards. They can also be used to create searchable PDFs or e-books.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>B. OMR (optical mark recognition) scanners are used to read marks that have been made on a piece of paper, such as on a test or survey.<\/li>\n<li>C. MSI (magnetic stripe reader) scanners are used to read data from magnetic stripes on credit cards, debit cards, and other cards.<\/li>\n<li>D.
