• Amazon announced Monday through a video posted online that it’s testing a grocery store in hometown Seattle, “roughly 1,800 square feet of retail space that is conveniently compact so busy customers can get in and out fast,” that has no checkout process, much less checkout lines.
• The store, dubbed Amazon Go, requires customers to launch a QR-code based app, which they scan upon walking into the site. The retailer’s “Just Walk Out” technology detects when products are removed from or returned to shelves, keeps track of them in a virtual cart, and totals the cost when customers depart the store. The app eventually automatically charges the card saved in the associated Amazon account and provides a digital receipt.
• The system leverages technologies used in self-driving cars, including computer vision, sensor fusion and deep learning, according to Amazon’s website. At the moment, only Amazon employees have access to the store, though others can sign up to be notified when it’s available more widely.
