Executive Summary
Tangem Wallet represents a revolutionary approach to cryptocurrency storage, combining the security of cold storage with the convenience of a credit card form factor. Unlike traditional hardware wallets that rely on USB connections, screens, and batteries, Tangem uses Near Field Communication (NFC) technology and a Swiss-certified secure element to create a truly maintenance-free cold storage solution.
Founded in 2017 and launched commercially in 2020, Tangem has quickly gained recognition for its innovative approach to hardware wallet design. The company has shipped over 500,000 cards worldwide and established partnerships with major blockchain projects and exchanges, making it one of the fastest-growing hardware wallet brands in the market.
What sets Tangem apart is its elimination of common hardware wallet pain points: no batteries to charge, no cables to lose, no screens to break, and no complex seed phrase management. Instead, users get a durable card that works seamlessly with their smartphone, providing bank-level security with unprecedented ease of use.
What is Tangem Wallet?
Revolutionary Card Design
Tangem Wallet is a hardware wallet built into a credit card-sized form factor. Each card contains a certified secure element chip that generates and stores private keys completely offline. The card communicates with your smartphone via NFC, eliminating the need for cables, batteries, or complex hardware interfaces.
Core Technology
- EAL6+ Secure Element: Swiss-certified chip used in government IDs and banking cards
- NFC Communication: Contactless interaction with smartphones and tablets
- True Cold Storage: Private keys never leave the secure element
- No Battery Required: Powered by NFC field during transactions
- Tamper-Resistant: Physical attacks destroy the chip and keys
How It Works
The Tangem system consists of three components:
- Tangem Card: Physical card containing the secure element
- Tangem App: Mobile application for iOS and Android
- NFC Connection: Secure communication channel between card and phone
When you want to make a transaction, you tap the card to your NFC-enabled smartphone. The app prepares the transaction, sends it to the card for signing, and then returns the signed transaction to the app for broadcasting to the blockchain.
