Amazon plans to open 3,000 stores without cashiers, even without guards, over the next three years.

Before the user wants to visit a supermarket, he will need to install the Amazon Go mobile application, and just attach smartphone to the special sensors.

After these manipulations of computer vision technology, deep learning algorithms and sensor systems will begin to track every step of the buyer. As soon as the buyer takes the goods out of the shelf and places it in a basket, the system will record this purchase on the account in a mobile application.

Recall that its first fully automated Amazon Go store opened in Seattle earlier this year.
