The New Standard: Classic Watches with Invis for Ultimate Security

How often do you forget a PIN or password? How many of them are written on sticky notes or saved in your phone? Every year, millions of accounts are hacked due to weak or reused passwords. Invis solves this problem once and for all – securely, conveniently, and stylishly.

The breakthrough Wristprint technology turns a classic watch into a modern tool for password- and PIN-free authentication for payments and access. It is the world’s first solution that recognizes the user by scanning the skin on the wrist and analyzing their movement patterns. The skin of the wrist has a unique structure, much like fingerprints or the iris of the eye, making it an ideal biometric marker. As a result, the device creates a unique, adaptive biometric profile stored exclusively on the device itself.

So what exactly is Wristprint? Wristprint is essentially a passkey – a login method that replaces traditional passwords. Instead of typing a password, you use biometrics, such as a fingerprint or facial scan. That’s something we already know. But Invis goes further, introducing two new biometric measurements that complement each other. Wrist scanning continuously verifies that the watch is being worn by its owner, while motion analysis detects anomalies in the way a person moves. This is continuous, automatic verification (so-called continuous authentication), ensuring that only the rightful owner has access to their data and payments, effectively eliminating the risk of identity takeover. Every person’s movement is absolutely unique. Believe us – there are no two people in the world who move in exactly the same way.

And what matters most to users besides security? Convenience, of course. Invis users don’t have to do anything at all to be authenticated. It’s enough to simply wear their watch. All the technology is hidden in the strap clasp, allowing users to enjoy effortless payments, open doors to their home, office, or car, and access their favorite applications – all with up to seven days of battery life on a single charge.

And now for the greatest reward. Invis technology is concealed within a stylish clasp for a classic watch. Placing the sensors in the clasp ensures maximum wearing comfort, measurement accuracy, and complete discretion. First, the appearance of the clasp gives no indication that anything is hidden inside – providing an additional layer of security. Second, the clasp fits most watches. You can wear any watch you like: one you received as a gift years ago, a family heirloom, or the latest fashion statement. In the background, discreetly, the Wristprint system gives you seamless access to mobile banking, data and online payments on your laptop, and even to your home or car.

While full biometric functionality is the next major milestone, the Invis ecosystem is already available today. The brand’s offering includes smart straps made from the highest-quality leathers that instantly turn a favorite timepiece into a contactless payment device. Thanks to cooperation with Fidesmo Pay, users can already pay securely with their classic watch at thousands of terminals worldwide, without sacrificing its original style. This is the first step toward full digital freedom of the wrist, available directly from the manufacturer’s website.

The interest from the watchmaking industry, the investment by Michał Dunin – entrepreneur, expert in digital communication and AI regulation, responsible among others for the revival of the iconic Błonie watch brand – demonstrates Invis’ potential in the premium segment. Confirmed support from the CARLSON EVIG Alfa VC Fund further proves that Invis is building a technology the market truly believes in.

“Our ambition is to combine two seemingly opposing worlds: classic elegance and advanced biometric technology. With Wristprint, a traditional watch becomes not only a symbol of style, but also an intelligent guardian of our digital identity.”
— Patryk Lamprecht, CTO and Founder of Invis

“The market for classic watches is the perfect space for our technology – customers here expect discretion and elegance, but they are also increasingly tech-savvy. Our goal is to deliver innovation that does not change the character of their watches, but enriches them with an entirely new dimension of utility. Yes, it’s a niche – but one with global reach.”
— Piotr Muranty, CEO of Invis

“Invis is redefining the concept of the ‘smartwatch’. Until now, we had to choose: either classic elegance and prestige, or payments and digital functions. With this technology, that dilemma disappears. As someone who has long combined digital strategy with the traditional luxury goods market, I see Invis as a solution with global potential. It proves that innovation can support tradition rather than replace it.”
— Michał Dunin, entrepreneur, expert in communication and AI regulation, investor in Invis

“Wristprint represents an entirely new generation of biometrics – a combination of the unique structure of the skin on the wrist and the movement dynamics characteristic of each individual. Our research shows that this non-invasive and user-invisible signal can be as unique as a fingerprint, while being significantly harder to spoof. By integrating skin-texture sensors and motion measurement into a standard watch clasp, we create a system that authenticates the user automatically, without passwords and without additional gestures – whenever the device is worn on the wrist.”
