TrackByStars® - Product identification with "Particle Fingerprint”

A forgery-proof digital product passport for your product

Do you want to identify and track your product in the global market individually, forgery-proof, robust and lifelong? Are you looking for a clear reference for originality, a digital twin or a unique assignment of components to a complete product, for example for a digital product passport? With the random 3D image of our fluorescent particles, your product receives a non-copyable fingerprint according to the random principle.

Robust Individual Product Marking

Labelling over the entire Life Cycle

To give your product a unique, invisible signature, our high-contrast fluorescent particles (tracers) are mixed into e.g. plastics before processing. Be it injection molding, extrusion or 3D-printing – our robust particles are randomly distributed, stochastically in the matrix material. This creates a distinctive, three-dimensional image. It only becomes visible when excited by a special light and shines like an individual 3D starry sky.

Individual Product Identification

Track & Trace by Fluorescent-Fingerprint

Each random pattern is unique. Due to the strong fluorescence, it can be captured using excitation, camera and our algorithm and stored in a database. It is measurable like a fingerprint. In this way, a product can be identified correctly and securely in seconds at any stage of the product cycle – and soon, all you need is a smartphone. For the first time, products can be tracekd individually and tamper-proof.
