Tangem Wallet
۱۴۰۵/۱/۲۷
Tangem Wallet is a hardware cryptocurrency wallet built in the form factor of a credit card with an embedded NFC chip. Developed by Swiss company Tangem AG, it stores private keys on a certified secure element and interacts with smartphones over NFC — no cables, no battery, no screen.
Design
- Form factor — plastic card, identical in size to a bank card
- Connectivity — NFC only (tap against a phone)
- Certified chip — EAL6+ secure element (co-developed with Samsung Semiconductors)
- No battery — powered by the phone's NFC field during use
- Durability — IP69K waterproof rating, operating range −25 °C to +50 °C, 25-year hardware warranty
A set is sold as 2 or 3 cards; all cards in a set share the same wallet so a lost card can be replaced by a backup.
Security model
The card generates its own private key internally — the key never leaves the chip and is never exposed to a computer or phone. Tangem originally shipped a seedless design (no recovery phrase), and now also supports optional BIP-39 seed phrase generation for users who want traditional backup.
Firmware is audited by Kudelski Security and Riscure. The wallet is non-custodial — Tangem cannot access, freeze, or recover funds.
Supported assets
Tangem supports 14,000+ tokens across 90+ blockchains, including Bitcoin, Ethereum, all EVM chains, Solana, Cardano, and major token standards (ERC-20, BEP-20, TRC-20, SPL).
Compared to Ledger and Trezor
- Simpler — no firmware updates, no buttons, no screen; setup is faster
- No USB attack surface — NFC-only connectivity
- Less flexibility — early models didn't support HD wallets (newer firmware added seed-phrase support)
- Price — typically cheaper per card than flagship Ledger/Trezor devices
