Amazon Go is be a brick-and-mortar store in which customers use an app to pay for items instead of waiting in line.
Using the Amazon Go app, customers enter the store, take the products they want and then walk out of the store.
The app keeps track of what is taken, so customers don't have to spend time scanning them or manually entering them in.
Amazon said the technologies for the Amazon Go store is the same as those used in self-driving cars.
The company said the "Just Walk Out" technology "automatically detects when products are taken from or returned to the shelves and keeps track of them in a virtual cart. When you're done shopping, you can just leave the store. Shortly after, we'll charge your Amazon account and send you a receipt."
The store, located in downtown Seattle, is currently only available to Amazon employees while it's being tested, but will open to the public in early 2017.
The store, which is about 1,800 square feet, is compact so customers can get in and out quickly.
It offers ready-to-eat foods, grocery staples and meal kits that can be made at home.
Customers will need an Amazon account, a supported smartphone and the Amazon Go app.
