Tangem Wallet - NFC-Powered Cold Storage Cards

The Tangem Wallet is a professional-grade hardware wallet that rethinks cold storage by putting your Bitcoin security in a form factor you can slip into your wallet. No screens, no batteries, no USB ports — just a credit card-sized cold storage solution powered by NFC and built on certified secure element chips.

How it works:

Each Tangem card contains a secure chip (EAL6+ certified — the same security standard used in passports and banking cards) that generates and stores your private keys. The keys never leave the card, and the card never connects to the internet. To sign transactions, you simply tap the card against your phone using the Tangem app — no cables, no charging, no firmware updates to worry about.

The beauty of Tangem lies in its simplicity. Unlike traditional hardware wallets with screens and buttons that can fail, Tangem cards are sealed, waterproof, and built to last decades. Drop it, bend it, forget it in your pocket through the wash — it keeps working.

Why multi-card sets?

Tangem sells in 2-card and 3-card sets for a reason: redundancy and backup. Each card in your set holds the same private key, meaning if you lose one, you've still got access. Store one at home, one in a safe, one with a trusted family member — you decide how to distribute your security.

This isn't a seed phrase you need to memorize or etch into steel. It's physical backup built into the product from day one.

Key Features:

• NFC-enabled — tap to sign, no cables or charging required
• EAL6+ secure chip — military-grade security in a credit card form factor
• No seed phrase management — keys generated on-card, never exposed
• Waterproof & durable — sealed design, no moving parts to fail
• Multi-card backup — 2 or 3 cards per set, each holding the same key
• Works with major wallets — supports Bitcoin, Ethereum, and 6000+ tokens via the Tangem app
• No registration required — no personal data, no accounts, no KYC

Who is Tangem for?

If you're after simplicity and durability over DIY customisation, Tangem hits the mark. It's ideal for those who want cold storage without the learning curve of seed phrases, derivation paths, or firmware updates. It's also a great option for gifting — hand someone a Tangem card, and they've got self-custody in their pocket.

That said, Tangem is a closed-source product. The firmware and hardware design aren't open for community audits like SeedSigner or Bitaxe projects. You're trusting Tangem's security implementation and their manufacturing process. For many users, that trade-off — convenience and professional build quality in exchange for transparency — is worth it.

Available sets:

• 2-Card Set — one primary, one backup
• 3-Card Set — extra redundancy for distributed storage

What's included:

• 2 or 3 Tangem cards (your choice)
• Quick start guide
• Access to Tangem mobile app (iOS & Android)

Tangem is a partner product we've chosen to carry because it fills a gap in the cold storage market — professional-grade security without the complexity. While we champion open-source projects wherever possible, we recognise that not everyone wants to build their own hardware or manage seed phrases. Tangem offers a solid, no-fuss alternative for those users.
