The Tangem Ring combines a ring and two cards in a hardware wallet for managing cryptocurrencies via a mobile app. It connects via NFC by tapping the ring or a card against an NFC-enabled phone, and access requires confirmation with a PIN or biometric authentication. Private keys remain on the certified secure chip and are never exposed to the internet.
The three physical devices are linked to the same wallet and use the same private keys, so losing one does not prevent access. No battery, charging, or maintenance is required, and a recovery phrase is optional. Activation is done through the Tangem app, which is used to send, receive, buy, swap, and manage cryptocurrencies and other digital assets. Transactions are confirmed in the app, as the device has no screen.
