The principle of "Rain Lotus-Cloud Code Payment for Personal Collection" is to monitor mobile phone WeChat and Alipay's QR code scanning payment receipt notifications through apps installed on mobile phones and call back to the developer application. When consumers make payments, they scan the developer's personal WeChat and Alipay collection QR code.
When you initiate a payment request, the system will automatically match the fixed amount payment QR code closest to the payment price. If no one is found (such as a payment QR code for this price is already used or does not exist), the system will use a non-fixed amount payment QR code (the payment page will prompt the consumer to manually enter the payment amount).
For example: If the price of your product is ¥ 35, then you can upload your own WeChat and Alipay to pay a fixed amount of ¥ 35. When you initiate a payment request with an amount of ¥ 35, the payment QR code of ¥ 35 will be returned to the consumer as a payment QR code.
