After the credit card is bound to Alipay, you can scan the code to pay, but you must meet the following conditions at the same time:

1. Because scan code payment belongs to online payment, the credit card bound by Alipay must have the function of online payment.

2. Because the personal QR code does not support credit card payment, the scanned QR code cannot be a personal QR code, but a merchant's QR code, which is also to prevent individuals from cashing out each other.

3. In addition, the merchant who scans the code must also open the credit card payment function, because then you can scan the code with the credit card bound by Alipay and complete the transaction without charging the handling fee, otherwise you will need a certain percentage of handling fee when paying.
