At present, there are many merchants who use Erweihuo cashier software in the catering industry. Basically, they can use QR code, WeChat or Alipay to collect cash. I think it is also beneficial for you to use WeChat or Alipay to earn money, and others will find it convenient. Now basically, vendors outside can use it, so I hope you can, uh, apply for a QR code, and then your business will prosper.
