Circular Ring 3 Adds NFC Payments, Drops Subscription for Core Health Features

Circular launched its Ring 3 Pro and Ring 3 Slim at IFA 2026 in Berlin on September 3. Both include built-in NFC for contactless payments and require no subscription for core health tracking — a direct challenge to Oura's recurring membership model in the growing smart ring market. Availability is expected in early 2027.
