Wearable Crypto Wallet Ring

The Tangem Ring Size 12 is a wearable hardware wallet crafted from zirconia ceramic for secure self-custody of cryptocurrencies and NFTs. It generates and stores private keys inside a CC EAL6+ certified secure element that prevents extraction. No batteries, cables, or charging are required as it draws passive power via NFC from a paired smartphone.

Offline NFC Communication Limits

The ring communicates exclusively through NFC with iOS and Android devices running the Tangem mobile app. It has no Bluetooth, Wi-Fi, or USB interface, so transaction signing only works at close range with an NFC-enabled phone. Firmware is non-upgradable, removing remote software attack vectors but also preventing future protocol changes.

Backup Cards and Recovery Scope

The package includes two backup cards that receive a secure clone of the ring's private key during activation. This seedless backup system lets you recover wallet access if the ring is lost or damaged. The ring and cards together manage thousands of supported assets, but recovery depends entirely on retaining at least one backup card.

Questions about this item

Should I pick the Size 12 ring or the Size 13 package?

How does the EAL6+ secure element protect my assets in daily use?

The chip generates and stores private keys internally so they never leave the ring, and non-upgradable firmware prevents remote software exploits.

What does NFC communication cap in practice?

The ring draws passive power from an NFC-enabled phone to sign transactions with a tap, requiring no battery, Bluetooth, USB or Wi-Fi.
