GoKawiilCircular unveils Ring 3 Pro and Slim smart rings with NFC payments
Circular has launched its Ring 3 series, succeeding last year's Ring 2, in two versions: a titanium Pro model retaining ECG-based AFib detection, and a lighter Slim model using biocompatible epoxy but lacking ECG tracking. Both rings add vibrating alerts for alarms and reminders and an NFC chip enabling contactless payments directly from the ring.
GoKawiil's interpretation of the reporting above, not reported fact.
Adding payment functionality and haptic notifications pushes smart rings closer to being standalone wearables rather than just health trackers, competing more directly with smartwatches. Splitting the line into a full-featured Pro and a slimmer, cheaper Slim option also signals Circular's attempt to broaden its market beyond dedicated health enthusiasts.
- Ring 3 Pro keeps ECG and AFib detection with a titanium build and up to 12 days battery life.
- Ring 3 Slim trades some health sensors for a lighter, more comfortable epoxy design.
- Both models now support NFC contactless payments and vibration alerts for alarms and reminders.
Oura Ring 4 — If Circular's Ring 3 has you curious about wearing your health tracker on a finger, the Oura Ring 4 is the smart ring you can actually order today. It tracks sleep, activity, and heart rate around the clock in a slim titanium band, and it's comfortable enough to forget you're wearing it.
