Tangem Ring (Ring & 2 Cards)

Portable hardware solution for cryptocurrency management that combines the security of a cold wallet with easy control via mobile phone.

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

Ease of Use: Access to the wallet is done by tapping the ring or card to the phone and confirming in the app. Usage is quick and similar to contactless interaction, but always requires authorization (PIN or biometrics).

Security:

• Certified secure chip (CC EAL6+)
• Protection against physical and software attacks
• Private keys remain on the device, never leaving the secure chip
• Smart backup system: The private key is stored on the ring and the two cards - no additional copies
• Audited software: The software has been independently audited by Kudelski Security and Riscure
• The seed phrase is optional

Three Devices. One Wallet: The ring and the two cards are linked 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 transactions.

Wallet Features: Using the mobile app, you can send and receive cryptocurrencies, buy, swap, and manage assets, as well as work with thousands of coins and tokens.

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

Important Information: A phone with NFC and the Tangem app are required. Wallet access requires authorization (PIN or biometrics). The device does not have a screen – transaction confirmations are completed through the mobile app.
