This is not possible. Although Fintech can repay credit cards (debit cards), you cannot directly use credit cards (debit cards) to repay Fintech.

As far as I know, Fenqile can only be repaid with a debit card. If you repay with a credit card (credit card), it is equivalent to withdrawing cash. However, if you don’t have money to pay back the installment loan temporarily, but you have money in your credit card (debit card), you can first withdraw cash from the credit card (debit card) and deposit it in your bank card, and then pay back the loan in installments.

Please note that credit card (debit card) cash withdrawals are subject to handling fees, and interest will be calculated at a daily interest rate of 0.05, so it is not very cost-effective.
