The opening will bring Amazon one step closer to its reported goal of opening as many as 3,000 of its futuristic Amazon Go stores by 2021. > So far, Amazon Go exists in three locations in Seattle, the home of its headquarters, and one in Chicago. Its latest location in San Francisco is set to open Tuesday. Amazon Go shoppers never wait in line to check out of the store. Instead, they scan an app when they walk into the store, and then Amazon Go uses so-called "Just Walk Out" technology comprised of sensors, deep learning algorithms and computer vision to automatically charge customers for their goods.
