Paying in Restaurants
Do you know if any restaurant or franchise replicated Uber / Lyft, or Amazon Go simplicity of payment by asking poeple to scan their phone to avoid having to deal with payments at the end of the meal ? One could just scan his phone, sits, order, eat then leave. He will his receive his bill on his phone and can tip on the app. Is that something doable ?
This is common in China, where paying meals using QR code + WeChat seems to be pretty much standard.
