Amazon is testing a fully automated grocery store that requires no human service. Customers use their smartphones to scan QR codes on products and then place them in a shopping bag. The store uses various automation technologies, including machine vision, sensors, and machine learning, to automatically recognize and calculate the price of the products.

The store is seen as a potential game-changer in the retail industry, offering customers a fast and convenient shopping experience without the need for human staff. The store is also expected to significantly reduce labor costs for Amazon. However, the technology behind the store is still in the early stages of development, and it remains to be seen whether fully automated stores will become more widespread in the future.
