Credit cards can be scanned to pay, but credit card scanned payments need to meet the following conditions:

1. The scanned QR code payment needs to support credit card payment, and most merchants QR codes can support credit card scan code payment, but personal QR codes usually do not support QR code payment.

2. The credit card needs to be enabled for online payment and real transactions must be generated, that is, credit cards cannot be used for transfers and red envelopes.

Most of the places where credit cards can be used to pay are large shopping malls or relatively large merchants that can use credit cards to pay.
