Tesco takes on Amazon Go with launch of ‘just walk out’ store

Tesco is fighting back against Amazon with its first “just walk out” store, where it is possible to buy groceries without having to scan items or visit a till.

The supermarket’s GetGo store in Holborn, central London, follows a small trial of a similar store at Tesco head office in Welwyn Garden City, which has been selling goods to the retailer’s staff since 2019.

Weight sensors in the shelves work with an AI system that can track an individual’s movement around the store and monitor the items they pick up via cameras, which follow each shopper. The AI system works by building a unique skeleton outline of each person rather than using facial recognition.

Shoppers must download the Tesco.com app to use the store, where they check in by scanning a QR code generated on their phone. Once inside, shoppers can pick up the items they want without scanning them. The bill is automatically charged to a shopper’s Tesco account when they leave.

The shop looks very similar to any other Tesco Express convenience store with the usual range of goods, from fresh flowers and alcohol to sandwiches, ready meals and bakery items. Cigarettes and alcohol are sold in a separate zone where a member of staff, about a dozen of whom are on duty on any day, is present to check that shoppers meet age restrictions.

The AI technology in the Holborn store has been developed in partnership with the specialist technology firm Trigo, led by two scientists who previously worked in the Israel Defence Forces. It is the first time it has been used by a UK retailer.
