In January 2018 Amazon opened its first checkout-free Amazon Go grocery store in Seattle, a "Just Walk Out" store that meant customers didn't have to queue for a cashier. The stores, which use surveillance cameras and sensors and weights connected to a virtual cart in the Amazon Go app, aim to revolutionise the way we shop.
The technology is used in Amazon Fresh stores too, and has sparked controversy for its perceived "Big Brother" qualities.
Since opening the first store, Amazon has also started selling the Just Walk Out technology to other companies. Various venues across the US, UK, Australia, and Canada use it today.
