Alipay may not allow credit card swiping for the following reasons: the merchant does not support credit card payment, the payment limit is exceeded or the credit card does not support demand payment, the user's credit card is abnormal, the user's credit on Alipay platform is bad, risky behavior or personal information is imperfect.
If you encounter this situation, you can contact Alipay customer service to understand the specific reasons. If you want to pay by credit card, you can select the "Bank Card" button on the Alipay payment page, then select "Credit Card", select a bank with this bank's credit card, and then click Next to see the limit of this bank. If the bank controls the risk, the credit card may be downgraded, frozen or blocked, and users need to apply for the right to use the card.
