1. Repayment with WeChat change balance: transfer the credit card repayment amount to the change balance of WeChat wallet, and then repay with the change balance. There is no handling fee in this way, but you need to make sure that there is enough change balance in your WeChat account.

2. Binding bank card repayment: bind the bank card in WeChat and then use it to repay. Under normal circumstances, there is no handling fee for bank card repayment, but you need to pay attention to check whether your bank will charge related fees.

3. Choose preferential activities: Sometimes WeChat will launch some preferential activities, such as full reduction and cashback. Choosing to participate in activities when repaying can reduce the handling fee or get some preferential treatment. It should be noted that payment information and bill amount should be confirmed no matter how repayment is made. If you have any questions or problems, please contact the card issuer or customer service staff in time to solve them.
