A customer-operated point-of-sale (POS) station. Also called a "self-scanning checkout," customers pay for and bag their own merchandise without interacting with a human cashier, although a support person is typically nearby and available.
The station includes a touchscreen display, barcode scanner, weighing scale, credit card reader and cash reader and deposit unit. After the customer scans the item's barcode, the item is placed in the bag, which is hanging on a scale. If the weight of the additional item does not jive with the item just scanned, the customer is asked to rescan it, otherwise an alarm will notify the attendant. See point of sale
