Today, Circular announced two new smart rings at IFA 2026: the Circular Ring 3 Pro and the Circular Ring 3 Slim. Both rings will enable wearers to make contactless payments with their fingers and receive haptic alerts to wake up without an alarm, as well as set health reminders.
The Circular Ring 3 Pro has FDA-cleared ECG for AFib detection, haptic vibration alerts, and NFC contactless payments. The Circular Ring 3 Slim is a more compact version of the Pro, without on-board ECG readings but with the same contactless payments and essential health monitoring.
