title: How well does the Android NFC API support Mifare Desfire?
body: <p>I'm likely to be working on a project where existing Desfire cards (used to access paid services) will be replaced with an NFC-capable mobile device. Can anyone point me to any resources to help me understand what's involved in a) replicating a Desfire card's data onto a mobile device so it can take the place of a card, and b) for the app to deliver NFC data in order to present to the reader as if it were a card. All relevant keys and access will be provided by the card issuer (if the project goes ahead) but I'm keen to understand the process in advance.</p>
  
  <p>I also need to understand how well the Android NFC API supports Desfire, because as far as I can see it only properly support Classic. <a href="http://developer.android.com/reference/android/nfc/tech/package-summary.html" rel="noreferrer">http://developer.android.com/reference/android/nfc/tech/package-summary.html</a></p>
