Which statement best describes how stock control data is updated at the point of sale?

• A. The barcode is printed on the receipt.
• B. The data is sent back to the POS where it appears on the receipt.
• C. When an item is scanned at the POS, the barcode number is sent to the computer.
• D. The system stops at the POS.

Answer: (C)

When an item is scanned at the checkout, the barcode number is sent from the scanner to the inventory computer system. That unique code lets the system identify which product it is and then updates the stock record by reducing the quantity on hand. This real-time update keeps stock levels accurate and supports automatic reordering if thresholds are met. Printing a barcode on the receipt or displaying data at the receipt does not update stock, and saying the system stops at the POS isn’t how stock control works.
