US grocery technology group Instacart is discontinuing its AI-powered Caper Cart after weak retailer adoption. The decision ends a Morrisons trial in Preston, UK, and cancels Carrefour Belgium’s planned pilot in Waterloo. The smart trolleys recognise and weigh products while offering personalised promotions and checkout functionality. Around a dozen US retailers use the technology. Carrefour is exploring alternatives, including rival smart trolley systems. (RetailDetail)
