I opened a China bank card in Foshan. Can I update my information at China Bank?

Of course.

At present, all bank cards are handled in real-name registration system, and ID card information is important information for bank cards. If the ID card expires, it means that the real name information of the ID card will also be invalid. Therefore, under normal circumstances, when the ID card expires, it must be updated in the bank. If not updated in time, it will affect the use of related functions of bank cards.
