title: Overwriting OffHostApduService to route APDU to SIM Card
body: <p>I'm working on a project to emulate a transport card on an Android phone,
  I've read through the Android Kitkat documentation and found that in order to emulate a card with a secure element I need to inherit from OffHostApduService. </p>
  
  <p>How ever after spending a lot of time on Google I couldn't find what to write on the onBind function to redirect APDU from the other NFC device to my mobile device SIM card. </p>
  
  <p>The card is NFC A &amp; B compatible does it means I can send commands to it using the NfcA or NfcB Class ? </p>
  
  <p>I work on a  Samsung Galaxy 3, Samsung Galaxy 4 Mini, which both have the openmobile api or at least the SmartCard API. I can't patch my system since the goal is to proove that it's possible to do so on market devices.</p>
  
  <p>Thanks for your help !!</p>
