Future of Vacuum Coated Security Devices Used In The Banknote Industry

The first vacuum coated security device used in banknotes was issued by the bank of England in 1984, it was metalized windowed thread on the £20. Since then, many vacuum deposited features have been adopted by banknote issuing authorities as a defense against counterfeiting, including the introduction of OVI (Optically Variable Ink) in 1987 from SICPA, and the OSD (Optical Security Device) issued by the Bank of Canada in 1989. In 1988 holograms were first introduced and although the technology started to gain traction on banknotes, the packaging industry commercialized the hologram, rendering its use as a high security device possibly compromised. Not to be outsmarted by the counterfeiters, the industry remains ever evolving, with recent advances coming in the form of engineered nanostructures and metamaterials.
