Tangem’s Battery‑Free Crypto Wallets: Credit‑Card Simplicity Meets the New Tangem Ring

Tangem Expands Its crypto Custody Playbook with Ring, Wallet 2.0 Backups, and a Powerful App

Breaking news: Tangem, the hardware custody pioneer, is widening its lineup in 2025 beyond its famous plastic cards. The company unveils the Tangem Ring-an elegant wearable wallet that leverages the same high-security tech as its cards-and reinforces its classic offerings with upgrades to its software ecosystem.

From Card to Ring: A New Form Factor for Everyday Crypto

The Tangem Ring marks a bold step into wearable custody. Crafted from zirconia ceramic for scratch resistance, the ring carries the same advanced security credentials as Tangem’s cards. It is designed to be waterproof and agreeable for daily wear, enabling payments and transaction signing with a simple wave of the hand. The move signals Tangem’s aim to bridge crypto security with everyday style, making secure crypto interactions nearly effortless.

Backups That Stand Out: Tangem Wallet 2.0

For users who prefer the traditional approach, Tangem Wallet 2.0 remains the benchmark. Sold in bundles of two or three cards, it enables users to create physical backups of private keys. if one card is lost, the remaining cards serve as backup keys, removing the anxiety of securely storing a 24-word seed phrase.

The Tangem app: A True Web3 command Center

Hardware is only as strong as its software. The Tangem app (available on iOS and Android) acts as a extensive Web3 hub,supporting access to more than 80 blockchain networks. Beyond passive storage, the app offers:

• In-app token swaps directly within the interface.
• The ability to stake assets to generate passive income on networks like Solana and Ethereum.
• NFT management through a clear, secure interface.
• WalletConnect-based access to decentralized apps (dApps).

Security remains central: the app is open source and has undergone audits by Kudelski Security. Importantly, Tangem emphasizes that user keys never leave the card chip, and no personal data is collected.

Seasonal Promotion And Open-source Assurance

In the spirit of the season, Tangem is partnering with a holiday promotion that gives back to the community through a Mystery Christmas Box, which includes a wallet and more. Fans are invited to participate via the brand’s social channels.

• User experience – Tap the ring on a compatible device to sign transactions, authenticate logins, or verify identity in a single motion.
• Security overlay – Ring includes an optional PIN‑protected “lock” mode that requires a secondary NFC tap with the user’s phone before activation.

Practical Use Cases

1. Retail payments – Pay at POS terminals that accept contactless crypto; the ring works like a contactless credit card but settles in blockchain assets.
2. Travel – Use the ring to access hotel keycards,public transport,and secure Wi‑Fi without exposing a phone screen.
3. Multi‑factor authentication – Combine ring tap with a biometric fingerprint on the phone for secure logins to banking apps.
