Can the self-service washing machine pay for the coin-operated washing machine via WeChat?

At present, the self-service coin-operated washing machine can use the WeChat payment function. There are many kinds of WeChat payment modules. One is realized by single chip microcomputer, and the price is favorable. However, it is more troublesome for users to pay. They first pay attention to their official WeChat account, then select the WeChat payment amount in the official WeChat account and enter the payment password. After paying the amount, the official WeChat account randomly sends a six-digit password, and then enters the six-digit password into the WeChat payment module of the washing machine, even if it is coin-inserted. There is also a relatively high-end, realized by Internet of Things equipment, and the price is slightly higher than that of single chip microcomputer. The device has a touch screen. When the user selects a program that needs laundry, the QR code will automatically appear. Users can scan the QR code and enter the payment password to work. The whole operation is very simple, and customers can also see the detailed data of equipment payment remotely.
