Decentralized Self-Service Checkouts

A shopper is identified upon entering a store and a shopping session is initiated for the shopper. Locations of the shopper within the store are tracked using wireless signals of a shopper's device. Items are scanned and/or weighed at distributed devices that report the item details to a server. The server correlates the shopper's current location to the reporting device and updates details for the shopping session. This continues until the shopper is ready to exit the store at which time the shopper can leave the store and have the server process payment for the transaction using a registered account. Alternatively, the shopper visits a payment station and provides cash or card to the station. The station reports the payment details and if cash change is due, the server instructs the station to dispense the correct change to the shopper.
