Inside Amazon's store of the future: No lines, no cashiers

Seattle

THE first clue that there's something unusual about Amazon's store of the future hits you right at the front door. It feels as if you are entering a subway station. A row of gates guard the entrance to the store, known as Amazon Go, allowing in only people with the store's smartphone app.

Inside is a 1,800 square foot mini-market packed with shelves of food that you can find in a lot of other convenience stores - soda, potato chips, ketchup. It also has some food usually found at Whole Foods, the supermarket chain that Amazon owns.
