German company develops a new security label system

A German company recently developed a new type of anti-counterfeit labeling system that uses laser beams to digitize data information in the form of micrometer-sized light spots and identify the authenticity of products by identifying holograms formed by light spots. This new type of anti-counterfeiting label It has broad application prospects in the fields of products and packaging.

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.
