GoKawiilCircular's Ring 3 adds NFC payments and vibration motor to smart ring
Circular unveiled its Series 3 smart ring at IFA, adding NFC payments compatible with Visa and MasterCard alongside a returning vibration motor for silent alerts. The lineup splits into the fully-featured Ring 3 Pro, with ECG and haptics, and the slimmer, lighter Ring 3 Slim that drops those features. Battery life nearly doubles to 12 days, and both models ship with a 700mAh charging case.
GoKawiil's interpretation of the reporting above, not reported fact.
By combining payments, health sensors like ECG and blood pressure trends, and haptic feedback in a titanium ring, Circular is pushing smart rings closer to smartphone-independent devices. This positions the company as a hardware-dense alternative to rivals like Oura, betting that consumers want fewer separate wearables for fitness, payments, and health monitoring.
- Circular's Ring 3 adds NFC payments compatible with Visa and MasterCard.
- Two versions launch: Pro with ECG/haptics and a lighter Slim without them.
- Battery life nearly doubles to 12 days, with a 700mAh charging case included.
