Amazon's New Grocery Store Let's You Skip the Check Out

Amazon Go Grocery is here, and it's everything you've ever dreamed of. That is, if you've dreamed of a grocery store that lets you take things off the shelf and leave without checking out.

Amazon Go Grocery is a full-size version of the existing Amazon Go Cashierless convenience stores. It's a brick-and-mortar retail store in Seattle's Capitol Hill district, and it has around 5,000 items, including produce, ready-to-eat meals, baked goods, meat and seafood, and wine and spirits. It carries Amazon-owned Whole Foods' 365 brand, as well as organic and local items, and big lots of big brands like Kelloggs and Coke.

Amazon says the grocery store offers low prices like like a Walmart or Publix, while offering the convenience of its Go model. Customers just need an Amazon account and the free Amazon Go app.

Here's how it works

When entering the store, customers scan their Amazon Go app, then start shopping. They can take items off the shelves and place them directly into bags. If they change their minds, they can put the item back. Then they can leave the store without going through any check out process—they can simply just walk out.

Amazon Go grocery uses "the same types of technologies used in self-driving cars: computer vision, sensor fusion, and deep learning." Overhead cameras and Just Walk Out Technology automatically detects when products are taken or returned to the shelves. A virtual cart keeps track of everything as the shopping is done. A receipt is later sent to the customer's Amazon account.

Even though everything is completely wallet-less, there are still people working at the store. Employees stand at the door to greet customers, while others restock the shelves, answer questions, and make product recommendations. If the customer intends on buying alcohol, an employee will check the ID upon entering.

The store is now open with other stores eventually opening in Los Angeles and beyond.
