Amazon expands no-cashier shopping

Amazon.com Inc. is opening a cashierless convenience store in the U.K., the first expansion of the company’s automated checkout technology outside the U.S.

The Seattle company said it will debut a 2,500-square-foot Amazon Fresh-branded store in London this week. The store, like its U.S. counterparts, will use an array of cameras and

other sensors to track shoppers as they pull items off the shelves, and it charges a credit card on file after they exit.

The stores represent the retail and technology giant’s biggest effort to reshape physical retailing. Amazon is also offering to license the system, which it calls Just Walk Out technology, to other companies.

Amazon has opened 26 cashierless convenience stores under the Amazon Go brand in the U.S. and two larger versions called Go Grocery.
