Secure product identity lets manufacturers authenticate components, digitize documentation, validate service history, and reduce operational risk from production through end-of-life.

Revenue & Brand Protection

Stop the gray market before it starts. With 10–20% of industry revenue at risk from counterfeiting and unauthorized resale, O-KEY empowers brands to shut down violators fast. Our patented, unclonable product IDs transform each unit into a secure, scannable proof of authenticity with no additional hardware required. Protect high-value goods, fast-moving consumer products, or serialized parts. O-KEY works across your product lines with a setup time as fast as 30 days.

Key benefits:

  • Prevent unauthorized resale
  • Protect margin and channel strategy
  • Maintain brand equity and customer trust
  • Legal-grade evidence for enforcement

‍

Traceability & Legal Proof

From product scan to court-ready proof. Every O-KEY generates a unique digital fingerprint, recorded at the moment of application and backed by tamper-proof AI verification. This traceable chain-of-custody turns every scan into a verifiable data point, tracking movement, ownership, and compliance history in real time.

→ Eliminate uncertainty.

Court-recognized documentation is crucial for blocking liability from tampered parts, verifying authorized service and ownership, and maintaining accurate records for recalls, maintenance, or compliance checks. An O-KEY ties this documentation to every component.

→ Simplify audits and claims.

Whether proving origin, spotting leakage, or enforcing service-level agreements, an O-KEY gives you the transparency you need, from batch level down to the individual unit.

Key benefits:‍

  • Instant traceability per item
  • Prevent liability from unauthorized distribution
  • Evidence admissible in legal proceedings
  • Identify supply chain breaches at the source

‍

Future-proof compliance

Built for what’s next. Ready today. Regulations are evolving fast. From the EU Digital Product Passport to global demands for traceability, ESG transparency, and lifecycle data. An O-KEY is designed to meet these standards now, not later. And can be updated at any time, even post-sale.

→ Legal-grade data in every scan.


Each O-KEY links to a secure cloud record of your product’s origin, materials, CO₂ footprint, and usage data. All accessible with a scan and easily updated anytime.

→ Circular economy made real.

Enable returns, refurbishments, recycling, or second-life use cases with confidence, with every unit backed by authenticated history.

Key benefits:

  • Simplify DPP and sustainability reporting
  • Ensure verifiable compliance at the item level
  • Power circular business models
  • Stay ahead of legislation and risk exposure

‍

Digitization & Engagement

Turn every product into a smart channel. Imagine your product could talk. With an O-KEY, it can. Each scan opens a branded, dynamic digital experience, from installation guides to loyalty programs, service history to circularity insights.

→ Beyond QR.


An O-KEY can look like a QR code but is infinitely more powerful: It’s unclonable, updatable, and designed to deliver high-value digital content, securely.

→ Easy to implement, instant to access.

No apps required. No new hardware. Just one scan with a smartphone unlocks a world of information, tailored to the context and user.

Key benefits:

  • Link users to product-specific data or content
  • Capture engagement and insights per unit
  • Automate service, support, or repurchase triggers
  • Create new post-sale revenue streams
