1 bar code
"The special identification code printed as a set of vertical bars of differing widths on books, grocery products, and other merchandise. Used for rapid, error-free input in such facilities as libraries, hospitals, and grocery stores, bar codes represent binary information that can be read by an optical scanner. The coding can include numbers, letters, or a combination of the two; some codes include built-in error checking and can be read in either direction." -
2 scanner
An optical input device that uses light-sensing equipment to capture an image on paper or some other object. Captured image data is converted into binary files that can be stored and manipulated by computer programs. -
