Ramdot ® is a chaosmetric security technology using a random dispersion of optically variable particles.
Chaosmetry relies on the recording of non clonable physical elements to create unique fingerprints.
For Ramdot ®, tiny variations in the initial conditions, during the dispersion of particles on the surface of the support, result in a final dispersion of particles that is totally unpredictable.
The characterization of a Ramdot® by its measurement gives a unique result allowing the identification of each of them in relation to the others.
Ramdot® uses optically variable particles whose colors and sizes can be selected to create a customized Ramdot®.
The thickness of the particles is sufficient to be perceptible to the touch. It is therefore easy to check the volume of the Ramdot® by passing a finger over it.
The optically variable particles of the Ramdot ® change color depending on the inclination.
Required equipment: None
Ramdot® is iridescent under UV light. An electronic signature of each Ramdot® is recorded to allow verification by eDMR® reader.
Required equipment: eDMR®
The dispersion of the optically variable particles of each Ramdot® is recorded in Prooftag Cerv to become the unique fingerprint of the product.
Required equipment: Smartphone, internet access
Users: General public
