Supermarket giant Aldi has followed in Tesco's footsteps and has opened a store where shoppers don't pay for their items with cash or card.
The discount supermarket’s new site in Greenwich, south-east London, will also allow customers to buy alcohol, using facial age estimation technology to check whether they appear to be over the age of 25.
The move follows in the footsteps of rivals Amazon and Tesco, who have both opened checkout-free stores.
