Bank card linking means that users add a credit card as a related card to their personal online banking account.

After activating online banking, users can add all the bank cards in their name to online banking. After adding a bank card, users can easily check the balance and status of the bank card, and realize automatic repayment between bank cards and credit cards.

There are the following precautions when adding a credit card:

1. To add a bank card, the user needs to bring a valid ID card to the bank branch to apply for the "Add Online Banking Registration Card" business.

2. The bank card and online banking account added must be the bank card of the same person with the same name.

3. The savings card of the added credit card account must activate the automatic transfer repayment service so that the bank can automatically deduct money from the savings card to repay the credit card.
