Tangem Ring (Ring & 2 Cards)

A portable hardware solution for managing cryptocurrencies that combines the security of a cold wallet with simple control through your mobile phone.

• Main Features: Ring + 2 cards = 3 physical devices for one wallet.
• NFC capability without cables: just bring the ring close to an NFC-enabled phone and use the app.
• Self-care solution, requires no battery or maintenance.
• Durable design for everyday use.

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

Security: Certified secure chip (CC EAL6+) that protects against physical and software attacks.

• Private keys remain on the device and are not exposed to the internet.
• Smart backup system: the private key is stored on the ring and both cards without any additional copies.
• The firmware has been independently audited by Kudelski Security and Riscure.

Private Phrase: The use of a private phrase is optional; the wallet can be used without it.

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

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

• Wallet Features: With the app you can:
  • Send and receive cryptocurrencies.
  • Buy, exchange, and manage assets.
  • Work with thousands of coins and tokens.

Quick Setup: Wallet activation takes just a few minutes via the app.

Important Information: A phone with NFC and the Tangem app are required. Access to the wallet requires approval (PIN or biometrics). The device has no display - transaction confirmations take place in the app.
