GoKawiilCircular unveils Ring 3 Pro and Slim with NFC payment support
Circular debuted two new smart rings at IFA, the Ring 3 Pro and Ring 3 Slim, both featuring built-in NFC for contactless payments via supported Visa or Mastercard cards—a capability absent from Oura and Samsung's Galaxy Ring. The Pro adds FDA-cleared ECG, blood-pressure monitoring, and a bigger battery lasting up to 12 days, while the Slim is lighter and thinner but caps battery life at 10 days. Pricing and availability have not been disclosed.
GoKawiil's interpretation of the reporting above, not reported fact.
Contactless payments could become a key differentiator in the increasingly crowded smart ring market, giving Circular an edge over larger competitors that have yet to add this convenience. If Circular can clarify card compatibility and payment mechanics, it may pressure rivals like Oura and Samsung to catch up quickly.
- Circular Ring 3 Pro and Slim support NFC payments with Visa/Mastercard, a first among major smart rings.
- The Pro model adds ECG and blood-pressure tracking plus longer battery life than the Slim.
- Pricing and full payment details remain unannounced despite the IFA reveal.
Samsung Galaxy Ring — While Circular's Ring 3 Pro is still awaiting pricing and availability, the Samsung Galaxy Ring is here now with sleep tracking, activity monitoring, and multi-day battery life in a titanium band. It's the benchmark that Circular is trying to beat, and it pairs tightly with Galaxy phones and the Samsung Health app.
