Answer: (B)

Barcode readers are commonly utilized at checkouts in supermarkets primarily for their efficiency in processing transactions. At a checkout, a barcode reader scans the barcodes on products, which instantly retrieves the price and product information from the store’s database. This technology speeds up the checkout process by eliminating the need for cashiers to manually enter prices and helps reduce human error in entering product details. In addition to streamlining transactions, using barcode readers also facilitates inventory management for supermarkets by keeping track of stock levels and enabling quick restocking processes. This ubiquitous application in retail leverages the advantages of automation and accuracy, which are essential for efficient customer service and inventory control.
