1. Log in to Online Banking Professional Edition and click Customer Management → Customer Information Modification in the column of Credit Card, and the modification will take effect immediately.
2. Manual telephone modification: dial the service hotline to verify the identity, and press 9 to switch to manual processing.
3. Go to the counter of the business hall.
If you have other specific questions, I suggest you call the customer service staff of the issuing bank, hoping to help you.
