Paper Certificates That Can’t Be Faked — Real-World Verification with Rubberduck Labs

At TAGBASE, we believe authenticity shouldn’t stop at luxury goods or high-tech devices — it should apply to anything that matters. That’s why we’re thrilled to announce our latest collaboration: Rubberduck Labs, a creative tech company pushing the boundaries of interactive learning and immersive experiences.

Their team, led by Andre Savic, recently launched a cutting-edge certification program. But they wanted more than a printed piece of paper — they wanted a way to ensure every certificate handed out was not just impressive, but impossible to forge.

That’s where TAGBASE came in.

🎯 The Challenge: Paper is Easy to Fake

We all know the problem. Anyone with a printer and a PDF editor can duplicate a certificate. And in the age of generative AI and deepfakes, forging credentials is becoming easier, not harder.

For companies investing in high-quality training and upskilling programs, this creates risk. How can you ensure that a participant actually completed your program? How can employers or regulators trust what’s printed on a document?

Rubberduck Labs Labs asked those questions — and decided to raise the bar.

✅ The Solution: Digital Trust, NFC-Secured

Using TAGBASE, each physical certificate was equipped with a tamper-proof NFC chip. These chips are cryptographically secured and connected to a digital record stored via our platform.

Participants simply tap their smartphone on the certificate, and — without needing to install any app — they see a live verification in their browser. A green check. A timestamp. A secure backend that proves authenticity.

It’s seamless, secure, and unforgeable.

🛠️ Tailored to Rubberduck’s Needs

Andre and his team were thrilled with how easily TAGBASE integrated into their certificate layout and fulfillment process. We worked closely to ensure the solution not only worked technically, but felt right from a design and experience standpoint.

Their brand identity remained intact — we just added a new digital layer of trust on top.

And the feedback? Overwhelmingly positive.

📱 Loved by Participants — No App Required

One of the things we care deeply about at TAGBASE is removing friction. Too many authentication systems rely on clunky apps or long verification flows. We believe trust should be effortless.

Rubberduck’s course participants were impressed by how easy it was to check their certificate — just a tap, and the authenticity was confirmed. No QR code scanning. No downloading anything. No registration.

It’s the kind of experience people remember — and talk about.

🌍 Why This Matters

Authentication isn’t just for million-dollar products or regulatory compliance. It’s for anything people care about getting right — and certificates are a perfect example.

They represent learning, credibility, and effort. Making them verifiable and secure is not just smart — it’s necessary.

With TAGBASE, even traditional formats like paper get a digital edge — bringing physical and digital together in a seamless, trusted experience.

🚀 We’re proud to support pioneers like Rubberduck Labs who don’t settle for “good enough.” They understand that authenticity is a feature, not a bonus — and that real-world applications deserve real-world protection.

Here’s to more verified moments, more secure credentials, and more happy customers.

Welcome aboard, Rubberduck Labs!
