Marks & Spencer is to trial a series of new self-service tills allowing shoppers to checkout their own goods so they can avoid queuing to pay for their shopping.
Known as SCOT - self checkout tills - each has touch-sensitive screen for shoppers to pass products over the barcode scanner before bagging them up.
The shopper can see a picture of each item scanned on the screen and the till also weighs loose fruit and vegetables. Payment is then made to a member of staff who covers a pod of four tills.
M&S said the system will reduce queues for shoppers and free up staff to work elsewhere in the store.
Trials start next month at M&S stores in London's Oxford Street, Uxbridge and Gateshead in the north east. If successful, the tills will be installed in M&S outlets across the country.
