Description

Seal module with seal face anti-theft mechanism

Technical Field

The invention relates to an intelligent seal, in particular to a seal module with a seal face anti-theft mechanism.

Background

The existing seal, especially the official seal, is the necessary office equipment that the unit or the legal person approve or prove the corresponding document validity, and the seal stamped on the document expresses the validity and authenticity of the document. Once the seal is lost, the seal is maliciously utilized by illegal personnel, and the serious consequence of directly or indirectly damaging the benefits of related personnel and institutions is caused, so that special personnel in a company generally manage the seal and are responsible for the use, preservation and maintenance of the seal. However, there are some special cases objectively, for example, some enterprises and public institutions borrow official seals, and seal managers cannot seal the seals at a predetermined place with seal persons; for example, the seal manager is on business, has a leave, and needs to use the seal, and the situation causes that the seal manager cannot ensure that the seal is used or has malicious use after being taken away, so that the intelligent seal appears on the market.

The traditional intelligent seal is authorized to be used through passwords or fingerprints, when the seal is lost or illegally used by stealing, the seal cannot be stamped after the seal is disassembled by violence, and therefore unnecessary troubles are generated for enterprises.
