Waitrose has brought in innovative smart trolleys powered by artificial intelligence which keep track of products as shoppers pick them off the shelves.
The small-scale trial at the upmarket chain's store in the Berkshire town of Bracknell is believed to the first time a UK supermarket has used so-called 'smart carts'.
The 'Shop-E' system is powered by handlebar-type devices made by Israeli software firm Shopic which customers can pick up from a charging bank at the entrance.
A shopper can release one of the futuristic-looking units after scanning their My Waitrose loyalty card, and then clip it onto a regular trolley to begin the shop.
Customers then scan the barcodes on items - similar to how they would with a self-scan handset now offered by some retailers - before placing them in the trolley.
