KembaraXtra-Computer Terms – bar code:
A bar code is a machine-readable identification code printed as a pattern of vertical bars with varying widths and spaces. These bars represent binary data that encodes information about a product, item, or document. Bar codes are widely used in retail stores, libraries, hospitals, and warehouses to identify items quickly and accurately. When scanned by a specialized optical device, the pattern is translated into digital information that computers can process.
Bar codes can represent numbers, letters, or combinations of both, depending on the coding system used. Some bar code systems include built-in error detection features to ensure accurate reading even if part of the code is damaged or partially obscured. In many cases, the code can also be read in either direction, making scanning faster and more reliable in high-volume environments such as grocery stores and distribution centers.
