The Tangem Ring functions as a hardware wallet for managing cryptocurrencies through a mobile app. It connects to two cards, and all three physical devices share the same wallet and private keys. Access is via NFC: tap the ring or a card against a compatible phone and confirm use in the app with a PIN or biometric authentication.
The certified CC EAL6+ security chip keeps private keys on the device, without exposing them to the internet. The wallet can optionally be used with a seed phrase, and is activated through the Tangem app. Use requires an NFC-enabled phone and the app; the device has no screen, so transactions are confirmed on the phone. The ring requires no battery or charging and is designed to operate for at least 25 years, with an unlimited number of transactions.
