Anonymity will not be displayed. I just tried to check the bank card number bound to my credit card on CCB Personal Online Banking. All the digits of the card number can be displayed completely, and the binding can also be modified or cancelled. Automatic repayment function. Just log in to personal online banking and select "Credit Card Repayment" and "Automatic Repayment Account Agreement" under "Credit Cards". It will pop up which credit cards you have added to personal online banking, and then click "Set automatic repayment" next to it. You can check whether there is a savings card number and what the specific card number is in "Deposit Account". Hope it will be adopted.
