“US supermarket chain Giant Eagle is piloting a checkout-free shopping and payments system that uses a network of cameras and sensors to let customers enter a store, select and place items in their shopping basket as normal, check out from their mobile phone and then simply walk out of the store. The retailer, one of the 20 largest grocery chains in the US, is working on the project with checkout-free technology startup Grabango . Grabango’s technology is designed to be retrofitted to existing stores, both small and large, and does not require customers to scan items as they shop in order to add them to their shopping basket.”
