Tesco is opening its first checkout-free store, where shoppers can pick up their groceries and pay without going to the tills.
The trial store uses cameras to replace checkouts, with the technology designed to track items as shoppers place them in their baskets.
Customers will need to scan the Tesco app on their mobile phones as they enter the store, and this will be used to pay for items.
