I think China is cashless society but not relying on internet servers. Beggars and street vendor have printed-out QR-code and no phone. You scan the code with Alipay-app and show the confirmation screen to the seller. This is not a real-time transaction. It is executed when the server is available.
Youtube-girl Qingyunji bought some water on remote mountain road using QR-on-cardboard and this is what I assume happened.
