@rafzat WeChat pay or AliPay. Scan QR codes. Very easy, though not quite as easy as tap-and-go credit cards. China basically went cashless in the space of a year. Anyone can accept payments: print a QR code, and let customers scan and send. Many stores have a voice thing that tells them when they've received a payment, so you just wait a second or two to hear your payment has arrived, then go.
