Samsung is exploring a new way to use a smart ring: built-in fingerprint recognition. The idea is simple. Putting the ring on your finger could verify your identity, making it possible to unlock your phone, sign in to accounts or approve payments without manually scanning your fingerprint.

How the Technology Could Work

A US patent application published on October 15 describes how the system might operate. Rather than asking you to press your finger against a separate scanner, the ring would read your fingerprint as you slide it onto your finger, reports GadgetsAndWearables.

During setup, the device would capture multiple scans and combine them to create a more complete fingerprint profile. Once registered, it could use a single scan to confirm that the ring is being worn by its owner.

Samsung has also considered comfort and battery life. According to the patent, small magnets and springs could allow the scanner's button to move slightly as the finger passes over it. This would help maintain contact with the skin without putting too much pressure on the finger.

The scanner would not need to run continuously, either. The button could activate it when the ring is put on, helping conserve battery power.

The same mechanism could also detect when someone removes the ring. When the finger moves away, the button would return to its original position, allowing the ring to notify a connected phone or other device that it has been taken off.

Could It Replace Your Phone's Fingerprint Scanner?

Samsung's patent describes several potential uses, including unlocking phones, signing in to accounts and authorizing payments. In effect, the ring could become a wearable security device that verifies your identity.

Imagine putting it on in the morning and having it recognize your fingerprint. You could then use the ring as part of the authentication process throughout the day. That would give smart rings a purpose beyond tracking sleep, activity and other health measurements.

However, there's an important question: would the ring need to scan your fingerprint every time you wanted to unlock something? If so, taking it off and putting it back on repeatedly would quickly become inconvenient.

One possible solution is to let the ring maintain a trusted status while it remains on your finger. Removing it could end that status, requiring you to authenticate again before using it for sensitive tasks. The patent's removal-detection feature could potentially support this approach, although Samsung has not confirmed exactly how the system would work.

Will It Come to the Galaxy Ring 2?

Turning the idea into a practical product could be difficult. Smart rings have very limited internal space, and adding a fingerprint sensor, moving components and supporting electronics without making the device bulky or uncomfortable would be a challenge.

There's also no guarantee that Samsung will release a ring with this technology. A patent shows that a company is exploring an idea, not that the feature is ready for a commercial product. Samsung has not confirmed whether fingerprint recognition will appear in a future Galaxy Ring.

Still, another Galaxy Ring is in development. Earlier this year, Samsung's digital health chief, Dr. Hon Pak, confirmed that the company was working on a successor. The next model could arrive as late as 2027.

Whether fingerprint recognition makes the final design remains to be seen. If Samsung can make it work comfortably and securely, the feature could give smart rings a new role in everyday digital security.
