Amazon's futuristic cashier-free store is expanding from its Seattle base. The claim to fame for Amazon Go, a hybrid grocery and convenience store stocked with prepared meal items and a variety of kitchen staples, is its lack of human staff: You check into the store with a code on the Amazon Go app on your phone, shop, and then are charged for the items you leave the store with, eliminating the sometimes time-consuming hassle of the checkout line. First announced as an employee-only beta in late 2016, Amazon opened its flagship Seattle location to the public in January. Now, the Seattle Times reports that the innovative retail experience will be heading to Chicago and San Francisco next. Amazon confirmed the expansion after publishing job postings for store managers in both cities, although exact store-opening dates are still under wraps.
