Wechat Vending machines

Vending machines Wechat – new trend in China!
Everything is easy: just scan qr code of snack which you like, pay using Wechat wallet, door will open and get it.
The principle of operation is almost like Packstation, even easier.
Early Wechat Vending machines could be found in Chinese underground, now start to post on the street!
Btw for Alipay money there are also vending machines, the principle is the same.
Still convenient! But in poor coutries it seems to steal everything, including the vending machine))
