Bubble Tag®

Bubble Tag® is a 3D chaosmetric feature based on a random generation of bubbles in a polymer

Bubble Tag® is the result of a chaotic process whose result cannot be mastered by human hand.

The generation of bubbles is a dynamic process particularly sensitive to initial conditions.

Small variations in those conditions lead to the outcome of an unpredictable constellation of bubbles.

The characterization of a Bubble Tag® by its measure, provides an unambiguous result, enabling the identification of each tag relative to the others, much like our individual fingerprints.

The positions, shapes and dimensions of the bubbles are totally unpredictable.

When this material is cut, constellations of bubbles are obtained with unique physical characteristics that are impossible to reproduce even by Prooftag.

Physical Characteristics


Bubble Tag® is produced in a polymer with a proprietary formulation. It has a very high resistance to heat, friction, UV and chemical attack.The probability of reproduction on a surface of 1cm² is 1/1080.


The thickness of the Bubble Tag ® can vary from 200 to 500 μm depending on the needs of the application. Bubbles cannot be destroyed or displaced, as the generation process is non-reversible.


Bubble Seal®

Bubble Tag® may be used to build tamper evident seals.

The Bubble Seal® integrated a unique constellation of bubbles associated to a serialized reference and a serialized 2D code.

It is the ideal security seal for document security and product protection.

Bubble Card®

The Bubble Card® integrates into its internal structure a Bubble Tag® visible by transparency on both sides of the card.

Any attempt to remove the Bubble Tag® implies the destruction of the card.

Bubble Cards® are available in several materials: PVC, PC, PET and Metal (bronze, steel).

Bubble Cards® may be used for identity documents or certificates of authenticity.

Security Levels


Bubbles trapped in a polymer reflect light.

Required equipment: None
Users: General public


An electronic signature is extracted from each tag
and recorded on Prooftag Cerv.

This signature can be verified by a Prooftag reader.

Required equipment: eDMR®
Users: Professionals


The image of a Bubble Tag® is recorded on Prooftag Cerv to become the unique fingerprint of each product.

Required equipment: Smartphone, internet access
Users: General public
