Tangem Ring (Ring & 2 Cards)

Wearable hardware solution for cryptocurrency management that combines the security of a cold wallet with simple control via a mobile phone. Elegant, discreet, and always ready for use. No cables, no battery, no charging.

• Main Features:
• Ring + 2 cards = 3 physical devices for one wallet
• NFC wireless access: simply tap the ring on an NFC-enabled mobile phone and use the app
• Self-custody solution
• No battery or maintenance required
• Durable design for everyday use

Ease of Use: Access to the wallet is granted by tapping the ring or card to the phone and confirming in the app. Usage is fast and similar to contact technology, but always requires approval (PIN or biometrics).

Security:

• Certified security chip (CC EAL6+)
• Protection against physical and software attacks
• Private keys remain on the device and are never exposed to the internet
• Smart backup system: the private key is stored on the ring and both cards – no additional copies
• Firmware audited by Kudelski Security and Riscure
• Seed phrase is optional: the wallet can be used without a seed phrase or with one during activation

Three Devices. One Wallet. The ring and the two cards are connected to a single wallet and share the same private keys. Losing one device does not mean loss of access.

Built for Long-Term Use: Designed for at least 25 years of operation and an unlimited number of transactions.

Wallet Features: Using the app, you can:

• Send and receive cryptocurrencies
• Buy, swap, and manage assets
• Work with thousands of coins and tokens

Important Information:

• Requires an NFC-enabled phone and the Tangem app
• Wallet access requires approval (PIN or biometrics)
• The device has no screen – transaction confirmations are done in the app
