Germany has developed a new type of spot hologram anti-fake packaging label

A German company recently developed a new type of anti-counterfeit labeling system, which uses laser beams to carry hydrogen information into the label in the form of micrometer-sized light spots. The holograms formed by the light spots are identified to identify the authenticity of the product. This new type Anti-counterfeit labels have broad application prospects in the fields of products and packaging.

The new system combines the advantages of data storage technology for holograms and polymeric material films by laser beaming a random number of light spots on a film of polymeric material that is only 20,000 meters thick. The light spot can store 1000 bytes of data information, which is more than 1000 times more than the current bar code.
