Barcode

A barcode is a series of parallel lines and spaces that represent data in a visual format. It’s commonly found on products and consists of two main components: a unique pattern of bars and spaces, and often an associated numerical code. When scanned using a barcode reader, the device translates the pattern into information, such as the product's price or inventory details. Barcodes enable efficient tracking and management of items in stores, warehouses, and libraries, streamlining operations and enhancing accuracy in sales and inventory control. Overall, it's a vital tool in modern commerce and logistics.
