LONDON -- Amazon has opened a cashier-free supermarket in London, its first bricks and mortar expansion outside the U.S. as the company bets on strong demand for its contactless shops.

Shoppers use a smartphone app to scan a QR code so they can enter the store. They can fill their shopping bags with milk, eggs or other groceries while cameras and sensors track what’s taken off shelves.
