When entering the unmanned supermarket, you only need to scan the electronic shelf label (esl) to choose and buy. "Unmanned Supermarket" USES artificial intelligence and biometrics, using radio frequency technology or scanning codes to identify changes in products. Currently, the unmanned supermarket USES "non-cooperative face recognition" technology, which means the system can accurately capture users' biometric characteristics and perform matching and calculation without looking at the lens. Users need to collect facial information and agree to automatic payment and deduction agreements when they first enter the store. These technologies allow supermarkets to shop, pick up and walk without having to scan the code to the store, and without having to check the fully intelligent operation of unmanned stores.
