Keycard is a Switzerland (CH)–based open-source hardware wallet project developed by Status, the team behind the Status mobile Ethereum client. It is a smart card–style hardware wallet designed for simple, secure crypto storage and seamless integration with the Ethereum ecosystem. Keycard is also a developer-friendly platform that enables dApp developers to build secure authentication and payment features into their applications. Unlike traditional hardware wallets, it is inexpensive, portable, and can double as a second-factor authentication device for decentralized applications.
