Miniature coded nickel particles, invisible at a glance and impossible to replicate outside Holoptica's own manufacturing process — applied across government documents, brand packaging and, increasingly, vehicles and assets.
microDOT particles are exactly what the name suggests: miniature nickel particles, produced in a wide range of sizes from 150µm to 1,000µm, in shapes from simple circles to complex polygons. Each one can carry alphanumeric text or a code on its surface, and on its reverse — a level of detail that's effectively impossible to fake without Holoptica's own manufacturing process.
Holoptica is one of only three companies globally capable of producing microDOT at this level. Combined with proDOC security paper, the sheer density and complexity of the marking overwhelms any attempt to reproduce it.
The microDOT surface can carry an enhanced 3D optically variable feature, with alphanumeric text or codes on the reverse.
Produced from 150µm to 1,000µm, in circles or custom polygon shapes — chosen to suit the application, not a fixed catalogue part.
Incorporated into proDOC security paper, microDOT adds a layer of density and complexity that overwhelms any would-be counterfeiter.
The same coded-particle principle protects three very different things — starting with secure documents, and now extending to vehicles and assets.
Incorporated into proDOC security paper for passports, certificates and other secure documents, adding a layer that's effectively impossible to replicate.
Applied to packaging and product components as a covert layer that complements Holoptica's holographic and DNA smartMARK technologies.
Thousands of coded dots applied across a vehicle's critical components make a stolen car traceable — and effectively worthless to strip and resell.
