High-tech automated convenience stores have entered Beijing and Shanghai.
One of them, BingoBox, opened in Shanghai in early July this year.
Customers scan QR codes to enter the store and select products, and then pay using their mobile WeChat wallets.
Last week, unmanned convenience stores opened in many neighborhoods in Beijing.
These stores use facial recognition to let customers enter after they upload a photo to register.
They also let customers pay via WeChat.
In addition, these stores have a microwave, a shared cell phone charger, a freezer, and a soy milk machine.
