Amazon Plans Checkout-Free Stores In San Francisco & Chicago

Amazon is bringing grocery stores without checkout lines to Chicago and San Francisco, expanding the concept beyond its pilot in Seattle. Known as Amazon Go, the store is like other small grocery shops with one crucial difference: it has no cashiers. To enter the store, customers scan a smartphone app and then cameras and sensors track what they remove from the shelves and what they put back. Amazon then bills shoppers’ credit cards on file after they leave.
