Holographic Overlay is a high-tech anti-counterfeiting material, which is made of holographic optical principle. Holographic optics is an optical imaging technology that can form images with three-dimensional effects in optical media. 

The holographic Overlay is made of a layer of thin film material, and its surface is specially treated to make it have characteristics of high transparency and high reflectivity. Inside the film material, some difficult-to-replicate patterns and information are recorded in three-dimensional form through holographic optical technology, and these patterns and information can be identified and verified by special readers. Holographic anti-counterfeiting film can be used in various fields, such as ID cards, bank cards, electronic products, cosmetics, auto parts, etc. It can effectively prevent counterfeiting and piracy, and improve product security and credibility.
