a seal

Abstract

The invention provides a seal which comprises a seal body and a seal face. The seal body is connected with the seal face. The seal is characterized by further comprising an intelligent chip, a trigger mechanism and a display screen. The seal face comprises a primary seal face and an anti-counterfeiting seal frame face. The anti-counterfeiting seal frame face and the primary seal face are located in the same horizontal plane. The intelligent chip is capable of generating a random code at the time of using the seal, recording the seal using time and transmitting the random code and the seal using time to a special database. The trigger mechanism is electrically connected with the intelligent chip and is capable of triggering the intelligent chip to generate the random code and record the seal using time. The display screen is electrically connected with the intelligent chip and is capable of displaying the random code generated by the intelligent chip. When the authenticity of a stamp needs distinguishing, the seal using time record can be retrieved from the special database for comparison with the time of the stamp, and the random code record generated at the time of using the seal can also be retrieved for comparison with the random code on paper. Consequently, true and false distinguishing is achieved, the risk that the seal is counterfeited is effectively avoided, and safety of the seal obtains double guarantee.

Description

However, counterfeit seals are flooding in the market at present, which brings many risks to business activities

[0003] At present, there are many anti-counterfeiting seals on the market, some of which engrave the registration number of the enterprise on the surface of the seal; some print patterns or symbols with special logos on the side of the seal body; loophole

For example, the registration number of an enterprise is now easy to check on the Internet, and it is not confidential; although the pattern or symbol of the special logo is difficult to copy, it is also difficult for ordinary staff in banks, taxation departments, etc. to identify , can only be effectively identified with the help of special tools, which also hinders work efficiency to a certain extent; and the seal with electronic anti-counterfeiting chip, because it is a precision device, is often damaged during the use of the official seal, and needs to be replaced frequently, and the cost is too high
