Counterfeiting is a global problem

Product piracy and manipulation affect entire industries — from patient safety to tax revenue and brand value. In 2021, counterfeit and pirated goods accounted for around USD 467 billion in global trade, up to 4.7 % of EU imports. A covert marker adds a layer of security that is invisible in daily use, yet unambiguous when you check for it.

  • Pharmaceuticals — patient safety and supply-chain integrity.
  • Electronics and spare parts — genuine vs. counterfeit components.
  • Currency, tax labels and official documents.
  • Cosmetics and consumer goods — brand protection.

What isishield solves

Three jobs, one tailored material solution — from the point of check to the recycling stream.

Authenticate

A clear genuine / not-genuine decision at the point of check — brand protection and imitation prevention.

Trace

Follow goods along the supply chain and detect diversion.

Sort & identify

Mark plastics and materials so they can be identified and sorted — supporting identification and recycling workflows.

Tailored to your requirements

Every product is different, so every solution is. We scale from a simple, high-volume marker for mass-market goods to a sophisticated, hard-to-copy protection with a demanding read-out for premium applications. You choose the level of security you need — and build only the level of protection your case needs.

We don't publish how the protection works — that's the point. The exact marker and read-out are defined with you, for your product, and stay between us.

One solution provider, the right network

One solution provider — we make the German-engineered marker and bring in the right read-out and integration expertise, so you don’t have to align several vendors yourself.

Marker material — made in Germany

Our core competence: the luminescent marker itself, engineered and produced in Germany.

Read-out & detection

The matching verification technology, specified and provided through our partner network.

Integration into any medium

Our markers can be worked into almost any medium — plastics, fibres, inks, coatings or the component itself.

From inquiry to sample

A short, guided path — no off-the-shelf security, just the solution your case needs.
