The self-report materials for bank cards frozen by criminal police need to be written based on your actual needs, such as writing a defense statement. The so-called defense statement is the facts and reasons for the prosecution or the appeal requests and appeals of the defendant and the appellee. If necessary, you can find a lawyer to assist you with the answers and defense documents.
Bank cards refer to all or part of the credit payment instruments issued to the society with the approval of commercial banks (including postal financial institutions) with functions such as consumer credit, transfer settlement, cash deposits and withdrawals, etc.
