The Tangem Ring wallet combines a ring and two cards for managing cryptocurrency through the Tangem app. Access is via NFC: tap the ring or a card against a compatible phone, then confirm with a PIN or biometric authentication. Setup is completed in the app in just a few minutes.

Private keys remain in the certified security chip and are never exposed to the internet. The ring and two cards are linked to the same wallet and share the same keys. The device has no screen, and transactions are confirmed in the app. No battery, charging, or maintenance is required.
