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.
