Because the bank will monitor the user's transactions, it will issue a warning message after discovering that the user has risky transactions, showing that there is risk.

Credit cards are not recommended to continue to be used after being warned of risks. It is best to consult the bank immediately and continue to use the credit card after it returns to normal.

If you want to avoid the risk warning of credit cards, you should use them in accordance with the norms to avoid the adverse effects of risk control on yourself.
