In stock control, what happens when an item is scanned at the point of sale?

• A. The barcode number is sent to the computer when scanned at the POS.
• B. The barcode is printed on the receipt.
• C. The data is stored in a separate ledger not used by POS.
• D. The system updates prices automatically across the store.

Answer: (A)

When an item is scanned at the point of sale, the barcode acts as an identifier that is read by the scanner and sent to the store's computer system. The barcode encodes a unique code that the inventory database uses to look up the product. The system then retrieves the product details (such as name and price) and immediately updates the stock records to reflect the sale. This real-time communication between the scanner and the inventory system is how stock control keeps track of quantities on hand and supports reordering decisions, sales reporting, and accurate checkout pricing. The other options don’t reflect what actually happens: printing the barcode on the receipt isn’t a required or primary outcome of scanning; storing data in a separate ledger outside the POS breaks the integrated flow between sales and stock; and prices updating automatically across the store isn’t caused simply by a single scan, as price changes are managed through centralized updates.
