LONDON— Aldi, the U.K.’s fifth largest supermarket, has opened its first checkout-free store in London, according to a news release. The trial store, which is located on Greenwich High Street, uses technology by AiFi, and specially positioned cameras detect which products customers have picked up and then charges the items to their Aldi Shop&Go account when they leave the store.

Customers must download the Aldi Shop&Go app, which will allow them to enter the store. Customers wishing to purchase alcohol or other Challenge 25 products will be able to use facial age-estimation technology to authorize their purchase. This technology, provided by Yoti, enables customers to confirm their age within seconds via the Aldi Shop&Go app. Those who opt to not use the system will instead be age verified by a store colleague.

“Today is the culmination of months of work, not least from the team here in Greenwich, and I’m looking forward to seeing how customers react to our trial,” said Giles Hurley, CEO of Aldi UK and Ireland. “This store utilizes the very latest in retail technology offering Aldi’s award-winning products and unbeatable prices to customers in a new and innovative way. The team are really excited about seeing customers come in and experience Aldi Shop&Go.”

Recently in the U.S., Choice Market and St. Louis-based Health Hospitality Partners have partnered to create the first autonomous markets in a health-care setting in the U.S. Dubbed Mini-Mart, the unique concept will launch on the University of Colorado Anschutz Medical Campus in the second quarter. It will feature Choice Now, a technology that also uses cameras and artificial intelligence to check out customers without the need for a cashier and offers consumers high-quality prepared food, natural groceries and everyday necessities.

NACS Daily reported on three ways shopping will be less time-consuming and more seamless because of technology advancements.
