**Title**: Proof of concept for integration of Keycard within mobile or desktop apps
**About Keycard:** Keycard is an open framework for smartcards in the crypto sphere. Smartcards are cost-effective, highly secure hardware, that can generate & store private keys, sign transactions with a tap on a mobile (android sdk available), or with a desktop (with a usb reader).
Keycard can be used as an easy-to-use and mobile friendly hardware wallet, bringing security and ownership over their keys to end users. Its form factor, tangibility and cost effectiveness can also be leveraged as an adoption tool, to bring new comers to decentralized services.
* Keycard has an Android SDK & Go SDK.
* Keycard is integrated with geth.
**Challenge description:** We’d love to see a proof of concept of integration of Keycard within mobile or desktop apps (e.g. wallets, web3 browsers) for security, dapps interaction, or payment purposes.
Full documentation and links to repos can be found here:
