BubbleTag Technology

BubbleTags are a revolution in brand authentication and security.

They are small tags consisting of a set of self-generated bubbles in a polymer substance. The bubble constellations are frozen in place - each tag a randomly generated and unique pattern - impossible to reproduce, even by the manufacturer! The calculated probability of reproduction is < 1/1080.

How is that of any use to us in a security standpoint? Most brand authentication and data security measures are reproducible with enough time and effort. Serial numbers printed on labels can be re-printed on blanks and holographic stickers are generated in large quantities. BubbleTags are irreproducible. For items that must be secured for long periods of time - years or decades, where a standard security label may have been duplicated by then, BubbleTags and their associated products are the solution.

Unlike other covert authentication products, BubbleTag verification does not require specialist skills or a laboratory to confirm authentication. It can be performed visually or by machine if automation is required.

There's just too much information to explain - start by exploring the BubbleTag product below as it's the core that makes the whole system work.
