title: how do you read the unique ID of an NFC tag on android?
body: <pre><code>Tag myTag = (Tag) intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
  Log.i("tag ID", myTag.getId().toString());
  </code></pre>
  
  <p>This gives me an ID like "[B@40521c40" but this ID changes every read.</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>Thanks.</p>
