If your bank card is bound to a securities account, you can check the bank card balance through the securities APP (some banks do not support this service).

For example, Guangfa Easy Gold Rush APP can query the balance through transaction → bank-securities transfer → bank-securities transfer → query the bank balance, and the balance can be queried after verification according to the system prompts.

If you don't have a securities account, you can try to inquire through the bank counter, telephone banking, mobile banking and online banking. Specific operating instructions suggest that you contact the bank customer service.
