Legal analysis: The bank card has been frozen by the Public Security Bureau. Generally speaking, bank cards are related to some legal and public security cases. Because according to the law, the Public Security Bureau can't directly freeze personal bank accounts. Only because of handling cases or judicial needs can the Public Security Bureau report to the court to freeze the relevant bank accounts involved. Don't worry when the bank card is frozen by the Public Security Bureau. After cooperating with the public security investigation, if there are no other problems, the account will generally be unfrozen in time. It doesn't matter if it can't be thawed in time. The time limit for public security to freeze deposits, remittances and other property according to law is six months, and it will be automatically unfrozen at the expiration.

Legal basis: Article 487 of the Supreme People's Court's Interpretation on the Application of the Civil Procedure Law of People's Republic of China (PRC) stipulates that the time limit for the people's court to freeze the bank deposits of the person subjected to execution shall not exceed one year, the time limit for sealing up or distraining movable property shall not exceed two years, and the time limit for sealing up immovable property and freezing other property rights shall not exceed three years. Where the person subjected to execution applies for an extension of the time limit, the people's court shall go through the formalities of continuing the seizure, seizure and freezing before the expiration of the time limit, and the extension period shall not exceed the time limit specified in the preceding paragraph. The people's court may also handle the formalities of continued sealing up, seizure and freezing ex officio. Where an applicant for preservation applies to continue property preservation, he shall apply to the people's court seven days before the expiration of the preservation period; If it fails to apply within the time limit, it shall bear the legal consequences of not renewing the insurance. When the people's court carries out property preservation, it shall inform the applicant in writing of the exact expiration date of the preservation period and the relevant matters concerning the application for extension of preservation in the preceding paragraph.
