Tangem Ring (Ring & 2 Cards)

A wearable hardware solution for cryptocurrency management, combining the security of a cold wallet with the simplicity of mobile phone use.

Main Features

• Ring + 2 cards = 3 physical devices for one wallet
• NFC access without cables: simply tap the ring to an NFC-enabled mobile phone and use the mobile app
• Self-custody solution

Access to the wallet is done by simply tapping the ring or card to the phone and confirming in the app. Usage is quick and similar to contactless technology, but always requires authorization (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, with no additional copies
