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.

Suica, Japan's IC transit card developed in the 1990s, stores a card ID and balance directly on its chip rather than relying on a central server. Each tap triggers a local read-write transaction with mutual authentication and a fresh encryption key, completed in under 200 milliseconds, all without a battery, powered instead by the electromagnetic field from the station reader.
