Discount supermarket chain Aldi has launched checkout-free shopping at one of its stores in Chicago, making it the first major US grocery retailer to deploy the technology in an existing, full-size store. 

The Aldigo technology, powered by Grabango, allows shoppers to skip the line and save time during the checkout process. It is available at the Aldi store at 2275 West Galena Boulevard in Aurora, Illinois. 

The technology uses computer vision to identify and keep track of every item in the store. After shopping for items, customers can pay with either their credit or debit card or with the Grabango app, at the Aldigo station near the exit. 

The system was added to the store without the need to make any changes to its planogram or product displays. Shoppers still have the option to check out with a traditional cashier.

“Aldi is continuously looking for new ways to be innovative and provide a best-in-class experience for our shoppers, and Aldigo is a great example of that in action,” said Eric Traxler, VP of IT at Aldi.
