Credit cards can be paid by scanning code, which is divided into the following situations:

1. After binding the third-party payment platform or bank APP, as long as the merchant and the third-party platform sign a credit card payment agreement, they can scan the code for payment.

2. After binding the credit card with Alipay, WeChat, UnionPay wallet, etc. , scan the payment QR code of the merchant, or let the merchant scan the payment QR code of your Alipay or WeChat or UnionPay wallet. As long as the merchant signs the credit card payment agreement, the credit card scan code payment can be completed.

3. Most banks' own mobile apps can also pay by scanning code, but fewer merchants sign contracts with banks to pay by scanning code credit cards than with Alipay, WeChat and UnionPay wallets.
