The Ring That Pays for Your Coffee: Inside Circular’s Audacious Ring 3 Series

Could your next credit card be worn on your finger? At IFA in Berlin, smart ring pioneer Circular officially unveiled the Circular Ring 3 Pro and Circular Ring 3 Slim, introducing built-in NFC contactless payments (supporting Visa and Mastercard) to the mainstream wearable market. In today’s episode, we investigate how this French startup is taking on Oura and Samsung by offering features the industry giants have yet to deliver.
We break down the technical specifications: the premium titanium Pro model boasting an FDA-cleared ECG and an impressive 12-day battery life, versus the ultra-compact, 2.35mm-thick Slim model designed to look more like jewelry. We also analyze the return of the haptic vibration motor for silent, on-finger alarms and reminders. Finally, we tackle the journalistic hard questions: the complex patent royalties Circular must pay to Oura, the hidden subscription model for advanced blood pressure and glucose tracking, and why their medical claims face a strict regulatory hurdle in Europe despite US FDA clearance. Join us as we explore if the Ring 3 is the future of digital wallets or a high-tech gamble.
