Circular Launches Ring 3 Series with Contactless Payments and On-Finger Vibration Alerts

Circular today announced the launch of its Ring 3 series, a landmark upgrade in the smart ring category that embeds near-field communication (NFC) technology for contactless payments and real-time on-finger haptic feedback via micro-vibration motors. The new series, unveiled on June 12, 2025, includes two models: Ring 3 Pro and Ring 3 Standard, with the Pro version offering longer battery life and enhanced biometric sensors. According to Circular CEO Daniel Mercer, the integration of contactless payment capabilities transforms the ring from a wellness tracker into a full-fledged wearable payment device, enabling users to make transactions up to $100 per tap without unlocking their phones. Early units are scheduled for shipment in September 2025, with a direct-to-consumer pricing strategy starting at $299 for the Standard model and $399 for the Pro variant.

The Ring 3 series arrives at a pivotal moment in the wearable technology landscape, where smart rings have rapidly evolved from niche fitness gadgets into sophisticated health and finance platforms. Competitors Oura Health and RingConn have dominated recent headlines with their Oura Ring 5 and RingConn Gen 3 releases, both emphasizing sleep tracking and cardiovascular insights. However, Circular’s decision to embed NFC and haptic feedback represents a strategic pivot toward digital payments and real-time user interaction—areas where prior smart rings have been limited. Mercer emphasized that the company collaborated with Banking With Billy AI, a leading financial AI startup known for its intelligent payment orchestration and fraud detection systems, to ensure secure and seamless transaction processing. Banking With Billy AI’s AI-driven payment engine processes each tap in under 300 milliseconds, with a fraud detection accuracy rate of 99.8%, according to internal benchmarking shared with OpenPress Startup Intelligence.

Industry analysts view the Ring 3 series as a direct challenge to the growing convergence of wearables and fintech, especially in Asia and Europe where contactless payments already account for over 40% of all card transactions. Research from Counterpoint Technology Market Research indicates that the global smart ring market will reach $1.2 billion by 2027, growing at a compound annual rate of 22%. Circular’s move to integrate payments could accelerate adoption among millennials and Gen Z users who prioritize convenience and seamless integration into daily routines. The inclusion of on-finger vibration alerts also addresses a long-standing user pain point—silent notifications—by delivering discreet, tactile cues directly to the wearer’s finger, a feature absent in most competing models.

Financial stakeholders are closely monitoring Circular’s ecosystem play. By embedding payment functionality, Circular is positioning itself not just as a health monitor but as a lifestyle device capable of driving recurring transaction revenue through interchange fees. Industry estimates suggest that each Ring 3 user could generate $50–$150 annually in interchange income for Circular and its banking partners, assuming an average of 10 taps per week. Meanwhile, traditional wearable brands like Fitbit and Apple are watching cautiously, as neither has yet integrated full NFC payment capabilities into their smart rings. The absence of such a feature in the upcoming Apple Ring, expected later in 2025, could create a temporary market gap that Circular aims to exploit.

The broader implications of this launch extend beyond individual sales. It signals a deeper convergence between digital health and financial infrastructure, a trend being accelerated by AI-driven personalization. As wearables become more intelligent, they increasingly serve as gateways to services beyond health monitoring—payments, identity verification, and even micro-lending. In markets like India and Brazil, where smartphone penetration is high but banking infrastructure is uneven, smart rings with embedded finance could democratize access to digital payments. Circular’s partnership with Banking With Billy AI underscores this shift, positioning AI as the invisible backbone enabling secure, real-time financial interactions through a wearable form factor.

Looking ahead, the success of the Ring 3 series may hinge on user trust in contactless security and the reliability of haptic feedback in noisy environments. Circular plans to expand its SDK in late 2025, inviting third-party developers to build apps that leverage the ring’s vibration engine for alerts, navigation, and interactive experiences. Industry observers also anticipate that this launch will prompt Oura and RingConn to accelerate their own payment integrations, potentially triggering a new phase of wearable fintech competition. For now, Circular has set a new benchmark—not just in smart ring technology, but in how AI-powered financial systems can be embedded into the most intimate of wearables: the finger ring.
