The Tangem Ring functions as a portable hardware wallet for managing cryptocurrencies through a mobile app. It connects with the two cards to form a single wallet, with the same private keys stored on all three devices. Access is via NFC and requires confirmation using a PIN or biometric authentication.

The wallet requires no battery, charging, or maintenance and has no screen; transactions are confirmed in the app. The CC EAL6+ certified security chip protects against physical and digital attacks, while private keys remain in the secure chip and are never exposed to the internet. The firmware has been independently audited by Kudelski Security and Riscure. A recovery phrase is optional, and the device is designed to function for at least 25 years and support an unlimited number of transactions.
