J Sainsbury, the first supermarket chain in Europe to license Amazon's "just walk out" technology, recently opened a checkout-free shop in London's Holborn district, where Amazon and Tesco also operate checkout-free stores.
Sainsbury's store is the first in which Amazon's technology was retrofitted to an existing store.
A QR code is needed for customers to enter the store, after which they need only place their items in a bag and exit.
The customer's purchase is determined using weight sensors, motion detectors, cameras, and software, and they are billed automatically as they leave.
Michael Gabay of Trigo, the Israeli retail technology company that provided the technology for the Tesco store, said the technology could be rolled out in rural areas where the costs of running staffed stores pose challenges for retailers.
