Authentix Launches Breakthrough Nano-Optic Plasmonic Feature

At the High Security Printing (HSP) Asia 2025 conference in Kuala Lumpur this month, Authentix unveiled PICO secure™, described as the world’s first nano-optic, plasmonic optical variable device (OVD) for polycarbonate identity documents. The feature – says Authentix – delivers always-on structural colour and movement, drawing on its award-winning nano-optic technology.

PICO secure provides dual-sided protection for passport polycarbonate data pages and other government documents, with its effects visible from either side. It does this by exploiting the unique properties of surface plasmon polaritons (SPPs) at metal-dielectric interfaces to create angle-dependent or independent, and wavelength-dependent, optical responses that are next to impossible to counterfeit.

During the launch, Alan Newman, Chief Product Officer at Authentix, explained how this patented Level 1 feature enhances public engagement. It also supports any document theme through highly customisable and intuitive authentication effects.
