Cardholders can log in to official website, the card-holding bank, access personal online banking, and then find "Modify Personal Information" in the left menu bar. Click Enter and fill in the correct payment password or password to prompt the answer. After entering, you can fill in the bound bank card.

Generally speaking, when applying for a credit card, the bank will ask the cardholder to bind a bank card, usually the cardholder's salary card, so that the bank will automatically deduct money from the salary card on the repayment date. If the bank card is not bound at the time of application, you can bind the bank card for repayment through telephone banking, mobile banking and online banking.
