Embodiment Construction

[0023] Such as figure 1 As shown in -4, the present invention is an anti-counterfeiting seal, which includes a printed body 1 and a casing. RFID tags can be implanted in the print body as unique identification information for each print body. The shape and structure of the housing can be similar to the existing stamp housing, the difference lies in the bracket 2 arranged at the bottom of the housing.

[0024] The bracket 2 includes a retaining ring 3 and a positioning ring 4 . The retainer 3 is composed of two relatively rotatable, preferably unidirectionally rotatable anti-counterfeit seals, that is, the retainer 3 includes a relatively rotatable inner print ring 31 and an outer print ring 32, both of which are supported by springs. The positioning ring 4 is arranged between the inner ring 31 and the outer ring 32 .

[0025] The contacting surface of the inner ring 31 and the outer ring 32 is provided with a plurality of matching teeth, that is, the outer surface of the in...

Abstract

The invention provides a security stamp. The security stamp comprises a stamp body (1) and a shell. The stamp body is contained in the shell. The lower portion of the shell comprises a bracket (1). The bracket comprises a retainer (3) and a positioning ring (4). The retainer (3) comprises at least two relatively-rotatable stamp rings (31 and 32). The positioning ring (4) is arranged between the two stamp rings (31 and 32). Convex-concave floral patterns (311 and 321) are correspondingly formed at the bottom end faces of the stamp rings. A complete ring-shaped security pattern is formed by the floral patterns of the at least two stamp rings. When the relative positions of the floral patterns are changed due to the relative rotation of the at least two stamp rings, the changing ring-shaped security pattern is generated. The invention further comprises a security stamp comparison system.

Description

technical field [0001] The invention relates to an anti-counterfeit seal and an anti-counterfeit seal comparison system. Background technique [0002] Seals are an indispensable notarization tool for enterprises, institutions and even government agencies. The existing mechanical seals may be lost due to careless storage, or may be used improperly due to unauthorized stamping. [0003] For this reason, electronic seals have been developed for effective management. For example, Chinese utility model patent 200520042143.5 relates to an electronic seal, which is provided with a counting device, a camera and a processor. When stamping, the camera is triggered to record the paper grain characteristics of the document to be stamped and processed by the processor for storage, so as to realize the traceability management of the stamp. [0004] However, in order to make the imaging device work, this electronic seal also needs to install a power supply inside, the structure is more c...
