PROBLEM TO BE SOLVED: To provide a self-scanning system capable of shortening settlement time, securing the secrecy on a fact such as the purchase of a commodity and preventing the generation of illicit utilization. SOLUTION: When a customer inserts a customer card 6 into an settlement machine 1 after selecting a commodity 4, a bar code seal 41 on the commodity 4 is scanned by a scanner 2. In addition to a reading function for the bar code seal 41, the scanner 2 is also provided with a writing function for writing status information in a data carrier 42 and writes purchased status in the data carrier 42 simultaneously with the scanning of each commodity 4. After completing the scanning of all commodities 4, the payment of cash or the like is executed. After the settlement, the commodities 4 are allowed to pass a security gate 3. If a customer tries to go out from a store without scanning the commodities 4, the security gate 3 recognizes that purchased status information is not written in the data carrier 42 and generates an alarm tone. |
