Tangem 2.0 is a card-shaped hardware wallet — no cables, no apps to install, just tap the card to your phone via NFC. Novel form factor perfect for travel or as backup. Bundle typically includes 3 cards for redundancy.
What Tangem is
Tangem cards are the size of credit cards. Signing happens via NFC tap-to-sign with your phone. No cables, no batteries, no separate device to charge or lose.
Trade-offs
- No display (relies on phone app for verification)
- Fewer altcoins natively supported than Ledger/Trezor
- NFC-only means smartphone dependency
When Tangem wins
- Travel — a card in your wallet is less conspicuous than a hardware device
- Backup — the 3-card bundle provides natural redundancy
- Onboarding non-crypto-native users — no setup complexity
Verdict
Tangem 2.0 is a novel hardware wallet form factor. Perfect for travel or as backup; primary use requires accepting the no-display constraint.
