UPC-A
UPC-A (Universal Product Code Version A) is a barcode system used primarily in retail to identify products. It consists of a 12-digit number encoded as a series of black and white bars, which scanners read to retrieve product information. The first six digits identify the manufacturer or brand, while the next five specify the product. The final digit is a checksum used for error detection. This system helps automate checkout, inventory management, and pricing, ensuring quick and accurate data capture at points of sale.
