Ramdot®

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.

Physical Characteristics

Material

Ramdot® uses optically variable particles whose colors and sizes can be selected to create a customized Ramdot®.

 

Volume

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.

Integration

Ramdot ® Seal

Ramdot® seals are built on a wide range of tamper evident security substrate.

This characteristic reduce the risk of removal and repositioning.
