When wechat pays, swipes the POS machine or scans the code, you can set the card to be bound in advance.
Open WeChat, click "+"in the upper right corner, and then select Collect and Pay.
In the middle of the payment interface, there is a line of small print "Use this payment method first". Click here to set up your binding card; If multiple cards are bound, you can choose this credit card to pay by default.
Credit cards can be used for receiving and paying QR codes of WeChat, Alipay, issuing bank APP and China UnionPay Express.
The premise of using credit card payment is that the merchant has opened a credit card to collect money. If the merchant's QR code payment does not open credit card payment, then consumers can't use credit card payment.
