title: NFC Card Emulation Mode and Peer to peer
body: <p>I want to build Android apps that can be used for a student attandance tracking system. Student's phone will acts as an ID (just push data) and teacher's phone will acts as reader (pull data). So my questions are:</p>
  
  <ol>
  <li>I know that a phone with Android 4.4 can use HCE but can an Android phone act as reader for that HCE emulated card?</li>
  <li>If it can, then which mode is better? HCE or peer-to-peer mode? What are the advantages/disadvantages of each?</li>
  <li>Are there any tutorials on this?</li>
  </ol>
  
  <p>thx before.</p>
