title: Android NFC with USB-NFC-Reader
body: <p>I have an Android tablet with Android 4.2. This tablet does not have NFC hardware. However I have an external USB reader: <a href="http://www.acs.com.hk/en/products/342/acr1252u-usb-nfc-reader-iii-nfc-forum-certified-reader/" rel="nofollow noreferrer">ACR 1252U</a>, that came with an <a href="http://android.acs.com.hk/" rel="nofollow noreferrer">Android library</a>. This library unfortunately only gives me basic functionality - read and write Tags. Altough this is working quite well, it is not enough...</p>
  
  <p>Because for my application I need to transfer files from my Android 4.2 tablet to other NFC devices (Android smartphones). So I need to put the NFC reader into peer-to-peer mode - which it supports. But how can I achive this with my setup? There indeed is an <a href="http://www.acs.com.hk/en/products/347/acr1252u-nfc-forum%E2%80%93certified-reader-software-development-kit/" rel="nofollow noreferrer">SDK</a> for that reader, but it's Windows only. </p>
  
  <ul>
  <li>Is it somehow possible, to use the <a href="http://developer.android.com/intl/zh-cn/guide/topics/connectivity/nfc/nfc.html" rel="nofollow noreferrer">built-in NFC-functions</a> from Android with the external USB reader?</li>
  <li>Is there another library for this reader, that supports peer-to-peer communication with other NFC-devices?</li>
  <li>Is there another Hardware that I can use, to make this work?</li>
  </ul>
  
  <p>Edit:
  <a href="https://stackoverflow.com/questions/9451411/how-to-connect-external-nfc-card-reader-to-tablet">The linked question</a> does NOT solve my problem:</p>
  
  <ol>
  <li>It is 3.5 years old. On might think, that in meantime has changed a lot.</li>
  <li>The answer to that question (= use the Android ACS library), is <strong>part</strong> of my own question... So it can't be the answer.</li>
