The store, located at the corners of California and Battery in the city’s financial district, is modeled much like the five existing locations. It largely serves prepared food, snacks, and drinks, with a focus on Amazon’s own line of sandwiches, salads, and meal kits. But the big innovation is its complete removal of the checkout process. > Instead of standing in line and paying a cashier, cameras and sensors track your movements through the store after you’ve scanned your Amazon account at the front and monitors when you take items off shelves. When you leave, you’re charged for what you’ve taken and given a digital receipt through Amazon’s standalone Go app. I took a tour of the 2,300-square-foot location late last week, when its windows were covered and its existence largely a secret until the San Francisco Chronicle revealed the address on Thursday using property records.
