Bank cards and credit cards are not associated. Only after the credit card and bank card are associated, the bank card will automatically repay the credit card debt.

After linking, you need to pay attention to the following points: 1. The debit card must have a sufficient balance. The method of linking a credit card to a debit card for repayment is very convenient for cardholders, but the debit card must be guaranteed The account has sufficient balance on the debit date. 2. The ID number must be consistent. It is required that the ID number used when applying for a debit card must be exactly the same as the ID number used when applying for a credit card. 3. Please pay attention to the effective time. The effective time of credit card automatic repayment business of each bank is different. If the automatic repayment does not take effect immediately after application, but will take effect on the next billing date after the cardholder sets it. Then the current bill still needs to be paid by the cardholder.
