Convenient repayment and automatic deduction.

1. Convenient repayment: By binding the bank card, cardholders can directly repay the money to the credit card through mobile banking, online banking or third-party payment platforms, without the need to perform separate repayment operations each time.

2. Automatic deduction: When the credit card bill amount exceeds the repayment amount, the bank will automatically deduct the excess amount from the bound bank card to ensure that the credit card will not be overdue.
