Laser holography using the MOIRE fringes formed by laser interference to record information. The accuracy of record information can reach 1000 lines/mm or more. The general printing method cannot be copied and imitated. The currency and documents are using laser holograms as anti-counterfeiting measures. Hao Neng has also developed based on conventional laser anti-counterfeiting technology, such as :
1. Invisible encryption and anti-counterfeiting technology,
2. Multi-channel holographic anti-counterfeiting technology,
3. 360 ° computer dot matrix holography technology,
4. Multilayer laser holography technology,
5. Dynamic coding anti-counterfeiting technology,
6. Special molding transfer image (such as transparent dielectric film) with anti-counterfeiting technology.
