This is Amazon's grocery store of the future: No cashiers, no registers, and no lines

Amazon is breaking into physical retail in a new way. 

The online retail giant revealed a new kind of physical store concept in a video published on Monday.

The store, called Amazon Go, doesn't work like a typical Walmart - instead, shoppers use an app, also called Amazon Go, to scan the products they plan to buy, then they can walk out of the building without waiting in a a checkout line. 

The idea is that Amazon's machine learning technology can automatically identify when a product is added to your cart, so you don't have to do it yourself. When you leave the store, Amazon automatically charges your Amazon account. 

The stores will sell ready-made food, staples like bread and milk, and other grocery products. Amazon says their stores are about 1,800 square feet, so they are relatively small compared to big supermarkets. 

The first Amazon Go store is located in Seattle, Washington, and it will open to the public in early 2017.
