Tangem’s Innovative Ring Device
Tangem, a Swiss company known for its cryptocurrency hardware wallets, has recently received a patent from the U.S. Patent and Trademark Office for an innovative ring device aimed at securely storing digital assets and facilitating blockchain transactions. Officially designated as patent number 12307443, this new technology centers around a ring-shaped cold wallet that incorporates a highly secure embedded chip capable of safeguarding a user’s private keys.
Features and Functionality
This cutting-edge ring employs near-field communication (NFC) technology, allowing users to initiate blockchain transaction signing simply by bringing the ring close to their smartphone. Crucially, the transaction signing process occurs entirely within the confines of the ring’s secure element, ensuring that the private key itself is never exposed outside the device.
Tangem emphasized in its announcement to Bitcoin.com News that this architecture is designed to keep private keys completely isolated, thereby providing a level of security equivalent to hardware wallets.
Recent Patent Achievements
In addition to this latest patent, 2025 marks the third U.S. patent awarded to Tangem this year. Previous patents pertain to a system for creating backups of private keys and a cryptocurrency payment card that supports self-custody transactions. With the newly acquired ring patent having a validity of 20 years, Tangem is positioning itself to leverage these patents for potential business partnerships and licensing opportunities.
Market Outlook and Expansion
Recognizing the burgeoning smart ring market, Tangem expresses optimism about the growth prospects in this space. The company forecasts that the demand for wearable payment and identity solutions will contribute to double-digit annual growth in the global smart ring sector. Founded in 2017 and based in Zug, Switzerland, Tangem reports serving customers in over 220 countries.
Their current offerings include card-shaped hardware wallets, and the introduction of the patented ring signals an expansion into the realm of wearable finance, catering to individuals who prioritize both self-custody and convenience in their financial transactions.
