The Bubble Tag is the result of a chaotic self-generation of bubbles within a transparent polymer. There is ,no technical means to reproduce this three-dimensional code as it is impossible to generate vacuums with identical shapes, sizes and positions within a material.

Classic authentication technologies are mass-produced and can therefore be mass-reproduced. Only technologies that cannot be reproduced by their own manufacturers can provide the assurance of efficient protection against forgery...

Just like a universal language, the Bubble Tag can be authenticated visually at any time in any place.

By entering the Bubble Tag reference via a computer or a mobile phone into a database system, one is able to access the recorded Bubble Tag image and make a visual comparison.

It is possible to officially and automatically control a Bubble Tag using a Prooftag optical reader.

These optical system use algorithms to calculate an electronic signature from each Bubble Tag. By connecting automatically to the database, the reader control the signature to the one stored after recording.
