Tangem

Secure NFC crypto self-custody cards

Tangem provides secure, customizable NFC-powered cards that act as self-custody instruments for cryptocurrencies and other digital assets. The cards enable users to manage keys and access assets via contactless NFC, leveraging asymmetric cryptography and proprietary firmware. A Kudelski Security audit underpins the security and privacy of the system. Unlike typical software-only wallets, Tangem’s hardware cards offer a tangible, offline-friendly way to hold digital assets, targeting individuals, financial institutions, and tech companies, and are sold directly online or through distributors. The company positions itself by removing middlemen and reducing infrastructure complexity to create a simpler, secure ecosystem for digital asset management, including CBDC-related solutions and secure identity verification. Overall, Tangem aims to make asset self-custody safer and more accessible for a wide audience.
