A German company recently developed a new type of anti-counterfeiting label system, which uses laser beams to drive data information into the labels in the form of micrometer-sized light spots, and identifies the holograms formed by light spots to identify the authenticity of products.
According to the German "Le Monde" electronic edition reported on the 25th, this set of anti-counterfeiting system was developed by two physicists in a company in Heidelberg. The new system combines the advantages of data storage technology for holograms and polymeric materials. The laser beam is used to burn a random number of light spots on a film of polymer material that is only 20,000 m thick. The film can be branded per square millimeter. One million light spots that form a three-dimensional hologram representing an image, a digital code, or a corporate identity. In addition, one kilobyte of data information can be stored in the spot, more than one thousand times more than the current bar code capacity, to introduce the product. In use, the hologram is reproduced through a special reading device and a laser beam, and the product information stored in the light spot is read out.
Although holograms on the market have been applied in anti-counterfeiting technology, because the traditional anti-counterfeit measures use printing technology, and there is no difference between the anti-counterfeiting labels of similar products, it has been unable to adapt to anti-counterfeiting needs. In contrast, the new tag anti-counterfeiting system uses randomly generated light spots, making the holograms of each tag different, and the spot itself also stores specific information, making the identification of counterfeit and inferior products more accurate and convenient.
Researchers expect that this new type of anti-counterfeiting label will have a wide range of applications in the areas of product and packaging, especially in the pharmaceutical industry. The World Health Organization warned: "In the world, 70 people die each day because of fake drugs."
