The Tangem Ring Size 8 works as a hardware wallet for managing cryptocurrencies through a mobile app. The ring and the two cards connect to the same wallet and share the same private keys, which remain stored on the devices. Access is granted by tapping the ring or card against an NFC-enabled phone and confirming in the app with a PIN or biometric authentication.

The ring requires no battery, cables, or charging, and the wallet is activated through the app. The app lets you send, receive, buy, and exchange cryptocurrencies, as well as manage assets. The device has no screen, and transactions are confirmed in the app.
