Amazon is opening its artificial intelligence-powered Amazon Go "cashier-less" store in Seattle on Monday.

The store allows shoppers to scan their smartphone with the Amazon Go app at a turnstile, pick out the items they want and leave.

By combining computer vision, machine learning algorithms and sensors, the online retail giant can tell what people have purchased and charges their Amazon account. If someone puts an item back, they aren't charged.

The store is not without employees - Amazon says there will be people there making food, stocking shelves and helping customers. The store will offer ready-to-eat breakfasts, lunches, dinners, and snacks, as well as some grocery staples like bread, milk, cheese and chocolates. It'll also have Amazon Meal Kits.
