Yes. You can use a bank card to transfer money to a credit card for repayment. When there is an outstanding balance on the credit card, transferring money to the credit card account is equivalent to repaying the credit card. In addition, you can also automatically repay credit cards by binding credit cards and bank cards, which can prevent users from overdue repayments. However, it should be noted that although automatic repayment is convenient, you must ensure that there are sufficient funds in the debit card associated with the credit card. Otherwise, the credit card will face full penalty interest.
