title: Android: HCE of 14443 type A card
body: <p>I'm trying to develop an application that uses Android NFC as smart card (Android 4.4.2 in HCE mode). I've read the <a href="http://developer.android.com/guide/topics/connectivity/nfc/hce.html" rel="nofollow noreferrer">guide about HCE on Android 4.4</a>. I used the example along with the Android 4.4 SDK. But if try to read the HCE-emulated smart card from another Android NFC device (Android 4.3) with an NFC reader application, I see only these logs:</p>

  <p>If I try, instead, to read a real smart card, it works as expected and I'm able to read the card:</p>
  
  <pre><code>TagID (hex): c4 2a 29 c8
  TagID (dec): 3291097544
  Technologies: MifareClassic, NfcA,NdefFormatable

  Mifare size: 1024 btes
  Mifare sectors: 16
  Mifare blocks: 64
