Morrisons is testing checkout-less stores that would allow shoppers to purchase groceries without queuing at a till.

The supermarket giant has been piloting technology at its headquarters in Bradford that would rival Amazon’s ‘just walk out’ stores.

The automated store, referred to internally as Project Sarah, is currently only open to Morrisons staff, but the grocer has plans to roll the tech out more widely if the pilot is a success.

According to The Mail on Sunday, Morrisons is working with US technology company AiFi, which uses cameras to track the objects customers pick up and put in their baskets. It then charges shoppers as they leave the store, via a smartphone app.

A source close to Morrisons described the technology as “phenomenal” and had been “very smooth” to-date.

Amazon has pioneered checkout-free grocery stores in the US and brought its first Amazon Fresh store to the UK earlier this year.

Its shops use cameras and shelf sensors, and require customers to scan a QR code upon entering and leaving the store.

Tesco is also testing a similar store at its Welwyn Garden City headquarters through a partnership with tech firm Trigo.
