Self-Scanning
During busy times queues build up at supermarket tills and customers may have to wait a long time to pay for the goods that they have purchased.
One method that can overcome the problem of long queues is self-scanning. In a supermarket which has a self-scanning system customers scan the barcodes of products as they put them into a trolley using a mini scanner on the trolley.
Ths scanner is connected to the supermarket stock database by a LAN using radio waves. As the products are scanned the total price of the shopping is calculated using the prices in the database. Once the customer has finished shopping the cost of the goods is transferred from his bank account to the supermarket's.
Supermarket employees make occasional checks on the contents of trolleys to ensure that customers are not tempted to put items into their trolleys without scanning them. Before customers are allowed to self-scan they must register with the supermarket so that they can be identified.
Some supermarkets now offer their customers the opportunity to shop from home using the Internet. A shopper can log on to a supermarket web site and select the products that he wants to purchase. The supermarket will then deliver these items to him at an agreed time. This is an example of electronic commerce (or e-commerce).
