I want to be a face-brushing payment agent. What about Mark?

POS machines are no longer working, and now they are all switched. The market prospect of brush face payment is very good. I am optimistic. I have heard of this company of Hangzhou Mark. The full name of the company is Hangzhou Youyun Technology Co., Ltd. I heard that it has cooperation with Alipay and WeChat, and it is still relatively formal. I suggest you know more about it!
