Go to the ATM of the bank, select personal online banking, then select the card number to log in, then enter the card number to be frozen and log in with the wrong password. Usually after 3-5 times, it will show: ...? "Frozen" and cannot be operated. If it is not possible to operate, please ask the bank staff to help complete it.

This freezing (the above operation) is only valid on the same day, and you should call the police immediately after the card is frozen. If the police station has not been frozen, it must be frozen again as soon as possible the next day. In order to prevent fraudsters from unlocking, you should use the fraudster's bank card to log in several times from time to time until a lock prompt appears.
