Embodiment Construction

[0014] like figure 1 , figure 2 and image 3 As shown, the housing 4 of the reversible stamp has a built-in spring 3, and the stamp 7 can be turned over in the housing 4 through the bracket 8. The middle part of the stamp body is provided with an ink pad chamber 6, and the integrated circuit chip fixed at the contact between the spring 3 and the housing 4 2 and antenna 1; antenna 1 is a coil with several sets of winding wires; the two ends of the antenna are respectively connected to the corresponding ports of the specific-purpose integrated circuit (ASIC) in the chip, and the antenna and ASIC are packaged in PVC and glued on the flip-type On the top of the housing 4 of the seal, the application-specific integrated circuit chip is composed of a control unit, an EEPROM and a radio frequency interface, and a group of unique and specific numbers is stored in the EEPROM.

[0015] The antenna and ASIC package are installed on the top of the stamp, the antenna has high sensitivit...

Abstract

This invention discloses reversible false proof seal and comprises reversible seal body. Set spring on top of seal body shell, fix special function IC chip with receiving antenna comprised control unit, ERPROM stored one set unique special serial number and radio frequency interface on contact position between spring and shell. It also discloses the network recognition use method. the invention can prevent effectively action of chiseling official seal secretly, increases greatly the false proof property and seal examination and approval efficiency and distinguish efficiency, and inhibits criminal behavior brought by seal.

Description

technical field [0001] The invention belongs to the technical field of electronic anti-counterfeiting identification, and in particular relates to a flip-type anti-counterfeiting seal embedded with a chip of a special-purpose integrated circuit and a micro-antenna, and a method for using the network identification of the seal. Background technique [0002] With the rapid development of science and technology, the field of seal anti-counterfeiting has also largely integrated high-tech means. In the prior art, from manual cutting out stamps to atomic seals, resin stamps, laser engraved stamps, and the use of fluorescent printing oil in the stamps, adding passwords to the stamps, adding fingerprints and electronic patterns to the five-pointed star, etc., have all improved the seal. Anti-counterfeiting performance. According to the relevant laws and regulations, the unit engraving the seal must submit a written application and seal style to the registration management agency af...
