There are many professional anti-counterfeiting features, including but not limited to the following:
Optical characteristics: the use of special optical effects or substances, such as optical discoloration effect, optical microstructure, infrared/ultraviolet reaction, etc. The authenticity of the product can be verified by observation or instrument testing.
Chemical characteristics: using special chemical components or markers, such as fluorescent dyes and tracers, the authenticity of products can be determined through chemical analysis or reagent verification.
Physical features: Features designed according to physical principles, such as micro-patterns, special textures and invisible patterns, need to be observed and identified by means of microscopes, infrared instruments and other equipment.
Biometrics: Anti-counterfeiting measures based on biological characteristics, such as DNA markers and biological structural features. , through biological analysis or testing to verify the authenticity of the product.
Digital features: By using cryptography, digital watermarking and other technologies, the anti-counterfeiting information is embedded into the product or its packaging, and the identification can be verified by scanning and decoding.
These professional anti-counterfeiting features usually need advanced technology and equipment to detect, and it is difficult for ordinary consumers to directly observe or judge. They effectively improve the anti-counterfeiting ability of products, help to crack down on counterfeit and shoddy products and protect the legitimate rights and interests of consumers.
