Bank cards are usually frozen for two reasons:
Banks in some countries and regions do not allow bank accounts to participate in digital fund transactions, nor are they allowed to trigger anti-money laundering systems. In this case, the bank card will not be frozen directly for the time being, but only part of the trading authority will be suspended. This situation is easier to handle. Just bring the account holder's ID card to the bank counter to provide relevant information and explain the source of funds.
The second situation is also the most troublesome judicial freeze. In this case, some funds in bank cards often go wrong, and people generally don't know what kind of situation it is. At this time, people's first reaction is often to call the bank to ask about the freezing time and understand the freezing situation. The first way to ask the bank for help is to unfreeze, and the second way is to freeze. The bank will explain some frozen cases to you and provide you with the police in charge of handling them. The first freezing is usually three days. These three days, the public security department is also investigating whether this bank card is suspected of the case.
After investigation, it will be thawed within three days. If the bank card is not thawed for more than three days, it will enter the second freeze. The second freezing period lasted for six months, and this freezing period was a bit serious. You or this bank card are suspected of some civil cases. As a cardholder, you need to submit some proof materials, and the public security department will also inform you in detail of the specific materials you need to submit. These six months are also the audit period. After verifying and confirming that you have not violated the law, you will be thawed. If the cardholder fails to provide relevant information within 6 months, or fails to pass the exam, it will enter an extended freeze period. The duration of the freeze period is infinite. The cardholder himself will also be listed as a criminal suspect, and these six months are also a very important period. As long as it is not suspected of committing a crime, it will be easily thawed within three days or six months, and the freeze will not be renewed. However, extending the freezing period often leads to judicial trial, and the trial result can only depend on the case.
Therefore, after the bank card is frozen, it is best to unfreeze it within half a year, otherwise it will be more troublesome. The cardholder's bank card has not been unfrozen within half a year and has not participated in criminal acts. If the result of the incident handling is inconsistent with the incident handling, you can also complain to the public security organ and the complaint department; You can also appeal to the public security organ at the next higher level or the people's procuratorate at the same level.
