There’s a moment most people know all too well. You’ve had a drink—or maybe two. You feel fine. But there’s still that quiet question in the back of your head before you grab your keys: Am I actually okay to drive?

That moment is exactly where EthyloKey fits in.

Instead of bulky breathalyzers, awkward blowing, or guessing based on how you feel, EthyloKey lets you check your alcohol level with a single touch of your finger. No mouthpieces. No calibration. No attention drawn. Just a fast, discreet answer when it actually matters.

The End of the Breathalyzer Era

Traditional breathalyzers work—but let’s be honest, they’ve never been subtle. They’re bulky, clinical, and not something most people want to pull out in public. EthyloKey flips that entire experience.

This is the world’s first touch-based alcohol detector. No blowing required. You simply place your finger on the sensor, wait a few seconds, and get a clear visual signal via a color-coded LED ring.

Green means go. Other colors let you know it’s time to pause, rethink, or call a ride.

It’s fast, intuitive, and designed for real-life situations—not roadside checks.

How EthyloKey Actually Works

The science behind EthyloKey is clever without being complicated.

When you consume alcohol, tiny traces of ethanol vapor are naturally released through your skin. EthyloKey uses next-generation ethanol vapor detection to read those traces directly from your fingertip.

The result? Indicative measurements designed to help users make more informed decisions — delivered through a device small enough to live on your keychain.

No consumables. No recalibration cycles. No maintenance reminders.

You just use it.

Discreet by Design (Because Privacy Matters)

One of the most underrated aspects of EthyloKey is how quietly it does its job.

There are no BAC numbers flashing on a screen. No loud alerts. No obvious signals to people around you. Just a subtle LED ring that only you notice.

That makes EthyloKey ideal for:

• Social gatherings
• Bars and restaurants
• Corporate events
• Festivals
• After-work drinks

It fits in your pocket, rests in the palm of your hand, or stays clipped to your keys. A touch instead of a blow makes all the difference when discretion matters.

Tested by Real People, Not Just Engineers

Before hitting the spotlight, EthyloKey spent time where it matters most: in the hands of real users.
Drivers, journalists, students, innovators—hundreds of people across Europe tested EthyloKey in everyday situations. Not staged demos. Not lab-only testing. Real nights out. Real decisions.

The feedback wasn’t scripted, either. Early adopters shared honest impressions based on actual use, helping shape the final experience into something practical, reliable, and easy to trust.

Track Patterns, Not Just Moments

EthyloKey doesn’t stop at a single test.

Pair it with its companion smartphone app, and you unlock a much bigger picture:

• Log drinks over time
• Track alcohol trends
• Set personal thresholds
• Build awareness of how your body responds

Over time, it becomes less about one decision and more about understanding your habits. That kind of insight is something traditional breathalyzers never offered.

No Calibration. No Maintenance. No Hassle.

Anyone who’s owned a breathalyzer knows the hidden cost: calibration.

Most traditional devices require regular recalibration to stay accurate. Skip it, and results become unreliable. EthyloKey removes that entire problem.

There’s:

• No calibration schedule
• No disposable mouthpieces
• No added maintenance costs

You charge it, use it, and trust it—simple as that.

Wireless Charging That Actually Makes Sense

EthyloKey is built for repeat use. On a single charge, you get up to 100 alcohol tests. When it’s time to recharge, just drop it on any Qi wireless charger.

Less than an hour later, it’s ready for another 100 tests.

No proprietary cables. No fiddling. Just effortless charging that fits into modern life.

Designed in France, Built for the Future

EthyloKey isn’t just another gadget—it’s a product shaped by where safety regulations are headed.
Designed and assembled in France, the device is backed by patented technology and rigorous research.

And it’s already aligned with upcoming legislation.

By 2026, the European Union will require all new vehicles to include alcohol detection systems under its General Safety Regulation. Similar measures are being evaluated in the U.S. through the Infrastructure Investment and Jobs Act.

EthyloKey is built with these standards in mind—ready to integrate with future automotive systems, not scramble to catch up later.

Award-Winning Innovation with a Purpose

EthyloKey’s impact hasn’t gone unnoticed.

The device won the IMPACT Challenge by Association Antoine Alléno, recognized at VivaTech for its role in promoting responsible driving and public safety. That recognition isn’t about flashy tech—it’s about meaningful, real-world impact.

A Small Device That Changes a Big Decision

Every drive starts with a choice.

EthyloKey doesn’t judge. It doesn’t lecture. It simply gives you information—quietly, quickly, and reliably—so you can make a better decision in the moment.

Sometimes that means driving. Sometimes it means waiting. Sometimes it means calling a ride.
And all of that starts with a single tap.

What Comes in the Box

Inside your EthyloKey package, you’ll find:

• The EthyloKey device
• Qi wireless charging compatible (charging pad not included)
• Access to the companion app
• Everything you need to start using it immediately

No setup headaches. No learning curve.

Final Thoughts

EthyloKey feels like one of those products that makes you wonder why it didn’t exist sooner. It replaces guesswork with clarity, awkwardness with discretion, and outdated tools with modern design.

It doesn’t try to be dramatic. It just helps you make a smarter choice—quietly, confidently, and on your own terms.

And sometimes, that’s exactly the kind of tech we need more of.
