A smart seal and authentication method

Abstract

The invention provides a smart stamp, which belongs to the technical field of office supplies and includes a bottom box, a movable seat and a locking assembly; the bottom box is a cylinder with an open end and a hollow interior; the movable seat is arranged inside the bottom box, and The bottom of the box is movably connected by a spring; the locking assembly is arranged on the movable seat, and the locking assembly includes a lock tongue, which can control the extension or retraction of the lock tongue. There is a lock hole inside the bottom box, and the lock tongue can be inserted into the lock inside the hole. Using such a smart stamp, the control module can control the locking tongue to retract through the authentication command input by Bluetooth, network or other means. At this time, the user can use the stamp normally, and judge the number of stamps by the pressure data input by the pressure sensor. After the authorized number of stamps, the bolt is extended to re-lock the stamp.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to an intelligent seal and an authentication method. Background technique [0002] The seal is used as a stationery printed on the document to indicate identification or signature. The seal can be printed on the text to indicate the act of signing.

[0003] In addition, according to the survey, when some users print the seal on the paper, in most cases, the direction of force cannot be completely perpendicular to the paper. There is an included angle of 0.5-3° on the surface. In this case, the seal pattern cannot be completely printed on the paper, resulting in the failure of the seal to sign the document.

[0004] When the documents are stacked together and stamped, the corners of other papers are placed on the stamp, and the height difference prevents the stamp pattern from being printed in the area near the corners. The above situation will also cause the signature of the document to be invalid.
