To check how many bank cards an individual has in a certain bank, you have to go to the bank counter or smart teller machine to check. Smart teller machines are very convenient for handling business. You only need to read your ID card to check. In addition, you can only check bank by bank. You cannot find out the bank cards of all banks by directly reporting your ID card.

In addition, some banks can also check by calling their customer service hotline. For example, if you want to check how many cards ICBC has, dial 95588. If you want to check how many bank cards China Construction Bank has, dial 95533.

Some mobile banks can check the bank cards in use under the user's name, but bank cards that have been dormant or have been suspended cannot be checked, so it is best to go to the bank to check. After checking, you can check the bank cards that have not been used for a long time. Cancel your bank card to avoid occupying the quota of a first-class card.

A first-class card is a bank card with no restrictions on deposits and withdrawals. If you already have a first-class card in a bank, the subsequent bank card can only be a second-class card. The cumulative daily transfer in and out amount is 10,000.
