Legal Analysis: Contact bank for details. If you find that your bank card has been frozen, you should contact the bank for consultation on working days. Usually bank card freezing includes the following three situations: 1. The transfer system of the People's Bank of China is frozen. If the transfer flow is too large and there are inappropriate comments, the bank card account may be frozen. The way to deal with this situation is to go to the bank to apply for an unfreeze, which usually takes 3 working days. 2. The policeman was momentarily stunned. This situation means that your bank card has collected black money, but it is not a bank card that directly collects black money. Usually, it can be defrosted automatically after the freezing time expires (72 hours). 3. The police requested the People’s Court to freeze the case.
Legal basis: Article 29 of the "Regulations of the Supreme People's Court on Seizing, Detaining and Freezing Property During Civil Execution by People's Courts". The period for which the People's Court freezes the bank deposits and other funds of the person subject to execution shall not exceed six months. This situation means that your bank card has directly received black money from the bank card. Such cases are usually frozen for more than six months, and the police can extend the freezing period until the case is closed or the case is dropped. The first two situations are easier to solve by freezing. If it is frozen for half a year, the bank will provide the phone number of the public security department for freezing.
