Germany has recently developed a new anti-counterfeiting label system

a German company has recently developed a new anti-counterfeiting label system, which uses a laser beam to inject data information into the label in the form of micron sized light spots, and identify the authenticity of the product by identifying the hologram formed by the light spots. The new system combines the advantages of holography and data storage technology of polymer film. A random number of light spots are burned on a polymer film only one tenth of a meter thick by a laser beam. Onemillion light spots can be burned per square millimeter of film. These light spots can form a three-dimensional hologram, representing an image, digital code or enterprise logo. In addition, perhaps this kind of gratifying light spot can be stored more than a thousand times. When in use, the hologram is reproduced through a special reading device and laser beam. 3. The control system of the tensile testing machine: read out the product information stored in the light spot. The label anti-counterfeiting system adopts the random testing machine, which is a precision testing instrument for measuring the mechanical properties, process properties, internal defects of metal materials, non-metallic materials, mechanical parts, engineering structures, etc. and verifying the dynamic imbalance of rotating parts under various conditions and environments. The light spots produced by the machine make the holograms of each label different. In addition, the light spots themselves also store specific information, making the identification of fake and inferior products more accurate Convenient
