The solution to the problem of Alipay risk control not allowing the use of credit cards is as follows:

1. Check the credit card status: First, confirm whether your credit card is normal and has not been frozen or expired by the bank. If the credit card status is abnormal, you need to contact the bank to resolve it.

2. Change the payment method: If Alipay does not allow you to use a credit card, you can consider using other payment methods, such as debit card, balance payment, etc. These payment methods may not be subject to Alipay risk control restrictions.

3. Contact Alipay customer service: You can contact Alipay customer service to learn the specific reasons and solutions. Customer service staff will provide corresponding help and suggestions based on your situation.

4. Increase credit rating: If your Alipay credit rating is low, it may lead to risk control restrictions. You can try to increase your credit limit by increasing your credit rating, such as improving your personal information, increasing your Zhima credit score, etc.

5. Wait for the risk control to be lifted: If none of the above methods can solve the problem, you may need to wait patiently for the risk control to be lifted. Alipay's risk control system will automatically adjust risk control strategies based on your credit record and behavior. If you have maintained a good credit record, risk control restrictions may be gradually lifted.
