Amazon will be opening more Amazon Go stores in the US and UK during 2019 - the latest rumour is that Amazon has now settled on a London site

Amazon Go gives you the option to buy your goods from Amazon in person rather than through

However, unlike other physical shops, it doesn't have any registers or checkouts. You simply walk in, pick out what you want and walk out. Amazon is calling this a "Just Walk Out" shopping experience.

What is Amazon Go?

Amazon describes Amazon Go as "a new kind of store with no checkout required". That means, when you shop at Amazon Go, you'll never have to wait in line. The store works with an Amazon Go application - you enter Amazon Go, take the products you want and, thanks to the app, just leave again. The first Amazon Go is basically a grocery store with roughly 1,800 square feet of retail space.

It works by using the same types of technologies found in self-driving cars, such as computer vision, sensor fusion and deep learning. This technology can detect when products are taken or returned to the shelves and keeps track of them in your virtual cart.

When you leave the store with your goods, your Amazon account is charged and you are sent a receipt.

What can you buy at Amazon Go?

Here's what Amazon was selling in its first Amazon Go store in Seattle:

"We offer delicious ready-to-eat breakfast, lunch, dinner and snack options made fresh every day by our on-site chefs and favourite local kitchens and bakeries. Our selection of grocery essentials ranges from staples like bread and milk to artisan cheeses and locally made chocolates. You’ll find well-known brands we love, plus special finds we’re excited to introduce to customers. For a quick home-cooked dinner, pick up one of our chef-designed Amazon Meal Kits, with all the ingredients you need to make a meal for two in about 30 minutes."

How does Amazon Go work?

Amazon Go app

To get started with Amazon Go, you need an Amazon account, a supported smartphone and the free Amazon Go app.

The video above shows customers opening the Amazon Go app on their phones, then holding it to a scanning device, which works like a subway turnstile and entering the store. Customers then put away their phones and began shopping.- picking up items, putting them in bags found in-store or brought from home (without needing to scan each item).

The Amazon Go app shown in the demo video has a navigation bar at the bottom with tabs for four screens: "Key", "Receipts", "About", and "More". The Key screen seems to bring up the QR code that the store's turnstiles scan to let you in, while the Receipts screen serves up what you bought after you've left.

Just Walk Out technology

Amazon said it is using a combination of artificial intelligence, computer vision and data pulled from multiple sensors to ensure customers are only charged for the stuff they pick up. The computer vision aspect seems to indicate that there are cameras being used to track you in the store. It'll be interesting to see whether Amazon can successfully prevent stopping theft and fraud.

A patent application filed by Amazon in early 2015 first revealed details about a new kind of retail store that would allow Amazon customers to pick items and leave without stopping at a cashier register or kiosk. The patent described a store that would work using a system of cameras, sensors and/or RFID readers to identify shoppers and their items.

According to this Amazon patent application, when a person exits the Amazon Go store, the store's system triggers a receipt that is sent to the shopper indicating the items sold and the purchase price. As to how Amazon would be able to connect a product with a specific shopper, the application described the use of cameras that would take photos.

They would take photos when people enter the store, when they removed items from a shelf, and when they left with items in their hands. There is also a mention of "facial recognition" and user information, which may include images of the user, details about the user like height and weight, user biometrics, a username and password, even user purchase history.

Needless to say, Amazon is being pretty vague right now, and we're not entirely sure if this patent application precisely describes the final iteration of Just Walk Out technology. However, if it is a camera-tracking system that also uses AI in the form of facial recognition or user biometrics, as well as sensors, such as something in the label of products, we could see the technology stoking some privacy concerns.

What is Amazon Go like? Is it the future of retail? 

We visited Amazon's original Seattle Amazon Go store to experience the "future of retail". The first thing to note is that the technology works extremely well - we had our receipt emailed to us in no time at all and the system wasn't fooled by us picking up things and putting them back through indecision. 

The most fascinating thing about the experience is how you feel about picking things up and putting them back. It's a bit like the feeling you get when removing something from your hotel minibar - have you been charged just by lifting it out of its spot in the cabinet? And there's a definite feeling that you could be stealing by "just walking out" - are security going to come and stop you? Are you being overcharged? Are you going to be undercharged? 

The actual store itself is just like a normal convenience store - don't expect to go in there and buy books, tech or clothes or anything else that Amazon sells online. It's basically quick-and-easy food and other groceries. It's just that there's no cashier. It was definitely an experience - and we're quite proud of the mug we bought...which says "just walk out" on it! 

Where is Amazon opening Amazon Go? 

There are now four Amazon Go stores in Seattle (one of which is a smaller concession in a Macy's), part of Amazon’s gradual rollout. There are now also four stores in Chicago and two in San Francisco. Check out the latest list of Amazon Go locations

We know that Amazon is also planning to launch an Amazon Go store in London's West End, the first outside the US.  

According to a report from The Wall Street Journal, Amazon hopes to one day open 2,000 grocery and convenience stores across the US. These stores might even have multiple formats, allowing it to better rival Target and Walmart and other big-box stores.

Amazon is reportedly considering the convenience store model the most, while the other store formats include a smaller drive-thru retail shop and a massive, Ikea-style discount chain that involves up to 40,000-square-foot stores. Customers will simply pick up their packages at the drive-thru. They can also order in-store via touchscreen displays or online, but then they'd go to the drive-thru to pick up their packages.
