Have you ever woken up thinking: "What if I lose access to my crypto right now?" If so, you're not alone. Thousands of investors lose sleep over this very question. Some write down seed phrases on paper that gets wet or burns. Others store keys in the cloud—only to find their wallet empty one day. Tangem offers a fundamentally different answer: a hardware wallet in the form of a standard bank card with a chip certified to biometric passport security levels. No seed phrases. No complicated devices. Just your assets—instantly accessible and absolutely secure.

What is Tangem: The Wallet That Redefined Security
Imagine holding a standard plastic card in your hand—thin and light as a credit card. No screen, no buttons, no charging cable. Yet, inside this card, your crypto assets are securely stored—be it Bitcoin, Ethereum, or thousands of other tokens. This is Tangem, a next-generation hardware wallet that redefines the concept of secure digital asset storage.
Swiss-based Tangem develops innovative solutions for securing crypto assets with one principle in mind: maximum security should not be complicated. Their flagship product is a set of 2-3 NFC cards (ISO 14443 standard), each containing a secure chip with EAL6+ certification—the same level of security used in biometric passports and bank smart cards.
Did You Know? The Tangem chip is rated for over 50,000 NFC sessions and a guaranteed data retention of over 50 years. Your assets remain secure for decades.
The key difference from traditional hardware wallets is the complete absence of a seed phrase. Classic devices (Ledger, Trezor) require you to write down 12-24 secret words. Tangem stores the private key directly on the secure chip, making it physically impossible to extract. Instead of a vulnerable paper backup, you have a reliable backup card.

How Tangem Works: Simplicity in Complexity
If you've ever paid with a contactless bank card, you already understand Tangem. The magic lies in NFC (Near Field Communication): simply tap the card to your smartphone for instant access to your assets. No cables, batteries, or firmware updates.
Three Simple Steps
Wallet Activation
Download the Tangem app, tap your card to your phone's NFC reader, and a private key is generated on the chip in real-time. No one, not even Tangem, ever sees your key. It is born and remains on the chip.
Asset Management
Use the intuitive mobile app to check balances, send and receive crypto, and interact with DeFi and NFTs. Every transaction is signed on the chip via NFC—your private key never leaves the card.
Seamless Backup
The set includes 2-3 cards. Set up backups in seconds. If your main card is lost or damaged, instantly restore full access with a backup—no seed phrases, no support tickets, no losses.
The card is completely passive without an NFC signal—meaning no remote electronic attack, virus, or hacker can access your keys remotely. It's a physical barrier that can't be bypassed by software. Your key isn't on the internet; it's in your pocket.
Tangem Security: A Level Unmatched by Most Wallets
When it comes to securing crypto assets, every layer matters. Tangem builds a multi-layered security architecture where each layer reinforces the next. Let's break down why this wallet has earned the trust of tens of thousands of users worldwide.
Manage assets with a single tap: an NFC session takes less than a second.
Multi-Layered Security Architecture
Hardware Security
- EAL6+ certified chip — the highest consumer-grade security standard
- Private key is generated and stored exclusively on the chip
- Physically impossible to extract the key without destroying the chip
- Built-in protection against side-channel attacks
- Resistant to electromagnetic interference
Software Protection
- Open-source firmware — independently audited
- Biometric authentication (Face ID / Touch ID) for every transaction
- Access PIN with limited attempts
- Automatic lockdown after multiple failed attempts
- Public codebase on GitHub for full transparency
Understanding "No Seed Phrase"
The absence of a seed phrase is a design choice, not a weakness. The private key is physically bound to the chip. If all cards are lost simultaneously, funds cannot be recovered. This is why we recommend storing backup cards in separate, secure locations.
Security Certification Comparison
| EAL Level | Typical Use | Wallet |
|---|---|---|
| EAL4+ | Most budget hardware wallets | — |
| EAL5+ | Ledger Nano X, Trezor (premium models) | — |
| EAL6+ | Biometric passports, bank smart cards | Tangem ✓ |
Tangem's firmware has passed independent security audits. The open-source code on GitHub isn't a marketing slogan—it's a real opportunity for experts to verify there are no backdoors. This level of transparency separates real security from marketing promises.
