Anti-counterfeiting labels can be divided into five categories based on their technical characteristics and functional evolution.
The first generation of products: represented by laser molded anti-counterfeiting labels, followed by temperature-change labels and nuclear track anti-counterfeiting labels. Laser-molded anti-counterfeiting labels are easy to counterfeit, and consumers lack the ability to identify their true and false. In the absence of comparability, 60% of counterfeit goods and 100% of genuine products are difficult to confirm. Although temperature-change labels are easy to identify, they are also easy to counterfeit.
The second generation of products: query-type digital security labels. Consumers can inquire digitally by phone, text message, and the Internet to confirm the authenticity of the label. However, since the anti-counterfeit digital is printed on the surface of the label, it can be easily forged.
The third generation of products: texture anti-counterfeiting labels. Texture anti-counterfeiting is a kind of anti-counterfeit technology based on the intrinsic marking of the label material as the anti-counterfeiting identification mark. Consumers can check the file through the Internet, fax, telephone, etc., to identify the authenticity. Random textures increase the difficulty of forgery.
The fourth generation of products: security line anti-counterfeiting paper and its application products, including various types of product anti-counterfeiting manuals and certificates, security cards, anti-counterfeiting labels. Consumers can easily identify the authenticity by recognizing whether the security thread is embedded in the middle of the paper. Because of the high threshold of imitation of such anti-counterfeit products, it cannot be forged by printing methods, and it is “easy to identify and hard to counterfeit”.
The fifth generation of products: the use of mobile Internet anti-counterfeiting technology labels. Consumers can use mobile phones to scan such anti-counterfeiting labels, automatically verify the authenticity online, and can be combined with texture anti-counterfeiting, security line anti-counterfeiting and other technologies.
Traditional anti-counterfeiting technologies have the defects of single function, high production cost, and inconvenient identification. Some new technologies also have problems such as high cost and non-generalization of identification tools. For example, most current material anti-counterfeiting technologies require the addition of materials or additional processes in the production and label printing process, and consumer verification also requires specialized equipment or tools, which are inconvenient to produce and use.
Currently used by many companies as anti-counterfeiting, anti-frying two-dimensional code labels, in fact, there is no anti-counterfeiting effect, it is just a symbol of information, not only can be copied, but also their own production, if the counterfeit goods produced by the counterfeit goods The two-dimensional code of the production company, then the genuine information scanned by the consumer may also be judged as counterfeit goods. Since the authenticity of the product and the query result have not established an inevitable link, many fraud cases investigated in recent years involve the issue of forging a two-dimensional code.
