Wafer-level laser anti-counterfeiting: capable of recording spatial changes in objects;
Laser anti-counterfeiting technology includes laser holographic image anti-counterfeiting, encrypted laser holographic image anti-counterfeiting and laser lithography anti-counterfeiting technology. Laser holography is a stereoscopic photographic technology that has developed rapidly since the advent of lasers in the 1960s.
- The 360° computer dot matrix holography technology combines and transforms light spots such as radial, ring, and spiral in the 360° observation range, and the motion is extremely strong. The double-layer holographic technology can uncover the holographic logo, and can also see the second anti-counterfeiting layer printed with patterns and characters, and has the double-proof anti-counterfeiting effect. The principle of fluorescence encryption holography is the same as that of RMB fluorescence encryption.
- Dynamic coding anti-counterfeiting is to place the trademark in front of the eyes, and slowly rotate the trademark to appear a continuous motion pattern. The telephone code anti-counterfeiting mark is made up of a combination of laser anti-counterfeiting technology and telephone code anti-counterfeiting technology. The authenticity can be checked by querying the unified central database. The nuclear microporous anti-counterfeiting mark is composed of laser anti-counterfeiting technology and nuclear micro-hole anti-counterfeiting technology, and the true and false can be distinguished by only one pen.
