Description
Tangem is a card-shaped hardware wallet that redefines the wallet experience by delivering top-level security, simplicity, and accessibility. Slim as a bank card and secure as a bank vault, it allows you to manage your crypto assets with a single tap of your phone.
How It Works
During activation, the card's embedded secure chip generates a truly random private key using entropy from its physical sensors. The private key never leaves the chip and cannot be extracted. Transactions are signed by simply tapping the card to your NFC-enabled phone.
Security & Certification
- Secure Element Chip — Industrial-grade chip that generates and stores private keys internally.
- Zero Cards Hacked Since 2017 — Over 6,000,000 cards in circulation with no security breaches.
- Fully Non-Custodial — No company, bank, or government can access, freeze, or restrict your assets.
- Seedless by Design — Backup cards replace the traditional recovery phrase. Multiple cards act as physical keys to the same wallet, eliminating single points of failure. A BIP39 seed phrase option is available for advanced users.
Key Features
- No Batteries, No Charging — Powered entirely by your phone's NFC module. Functions for decades under normal conditions.
- Three Cards, One Wallet — Purchase 2 or 3 cards; each holds the same wallet. One tap links them for secure recovery.
- Buy, Sell, Swap, Earn & Spend — Access integrated third-party services directly within the Tangem app.
