1. After a customer scans the goods and puts them on a conveyor belt, a laser checks the item and price. 2. One of the latest ideas is a self-checkout system that allows customers to scan their own items and charge them to cards and depart. 3. Self-scanners allow customers to scan their purchases as they shop, saving time at checkouts. 4. The system allows customers to scan their own groceries and pay a cash machine that can provide change or accept a debit or credit card. 5. When customers scan in a bar code, DigitalConvergence automatically plugs the right address into their Web browser. 6. Wal-Mart also has some self-service checkout counters, enabling customers to scan and pay for merchandise themselves. |
