Android app for performing Yubikey Neo NFC challenge-response
YubiChallenge is an Android app that provides a simple, low-level interface for performing challenge-response authentication using the NFC interface of a Yubikey Neo. This app should be triggered using an implicit intent by any external application wishing to perform challenge-response. The intent name should be "com.yubichallenge.NFCActivity.CHALLENGE" and the challenge should be stored in an extra called "challenge". The response will be returned by the intent in an extra called "response".
This is a set of NFC applications that uses a common framework that interacts with the JSR 257.
There are two application examples: NFCMuseum and Picking.
