Long-term dormant accounts: If your mother has bank cards in some banks, but has not used them for a long time, and the balance is small (such as not exceeding 10 yuan), these accounts may be regarded as "dormant accounts". According to the requirements of relevant laws and regulations, banks can clean up such bank cards that do not meet the management requirements irregularly or regularly, that is, cancel their accounts.

Extra bank cards: Sometimes, people may apply for multiple bank cards for various reasons (such as bank promotion, company or unit requirements, etc.). ), but they don't really need that much. If the number of bank cards exceeds the regulatory requirements, banks may also cancel these redundant accounts.

Illegal activities or misappropriation: if the bank finds that the bank card is used for illegal activities (such as money laundering, online fraud, drug trading, etc.). ), or the bank card is stolen by others, involving illegal and criminal acts, the bank will cooperate with the judicial organs to cancel the bank card.

As for the word "forced account cancellation" you see, it usually means that these accounts are forcibly cancelled by the bank for some reason (such as long-term unused, violating bank regulations, involving illegal acts, etc.). ). In the case of forced account cancellation, the bank may notify the customer and ask him to handle account-related matters as soon as possible (such as withdrawing account balance and handling unfinished transactions). ).

As for why your mother saw so many card numbers, it may be because she had handled some bank cards before but forgot them, or that others (such as family members or former employers) handled them for her. In order to solve this problem, it is suggested that your mother contact the relevant banks to find out the details of these bank cards and decide whether to keep or cancel these accounts.
