Morrisons is testing out stores with no checkouts or staff in a move that would rival Amazon.
The supermarket is reported to be working with US technology company AiFi, which uses cameras to track the objects customers pick up and put in their baskets.
The technology then sees shoppers charged through a smartphone app - meaning they don’t need to go to a till to pay.
Morrisons is said to be testing the concept at its Bradford head office store, which is open to thousands of staff.
“A couple more” stores are said to be in the pipeline to trial out the concept - known internally as Project Sarah.
A source close to Morrisons told the Mail on Sunday: “The tech itself is phenomenal, which uses cameras rather than weights – it has been very smooth.”
The concept of checkout-free stores is already being used in Amazon Fresh shops, the first one of which opened in the UK in March this year in Ealing, London.
Four more have opened in the capital since then, including in White City, Wembley Park, Canary Wharf and Chalk Farm.
All its stores in London have technology in place that lets customers pick up items and walk out of the store without using a till.
Instead of interacting with staff, cameras monitor what items shoppers pick up and take out of the store. Their Amazon account is then charged when they leave.
But Morrisons isn't the first Big Four grocer to express an interest in checkout-free stores.
Tesco last month confirmed it has been trialling the concept at its head office in Welwyn Garden City, Hertfordshire.
The first one that will be open to customers is set to be unveiled in the coming weeks and months, although Tesco has yet to reveal the location.
