    Tag type identification example:

    Intent intent = getIntent();
if (intent.hasExtra(NfcAdapter.EXTRA_TAG)) {
  Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG));
  if(NfcA.get(tag) != null)
    Toast.makeText(this, "Type A tag found!", Toast.LENGTH_LONG).show();
  else if(NfcB.get(tag) != null)
    Toast.makeText(this, "Type B tag found!", Toast.LENGTH_LONG).show();
  else if(NfcF.get(tag) != null)
    Toast.makeText(this, "FeliCa tag found!", Toast.LENGTH_LONG).show();
  else if(NfcV.get(tag) != null)
    Toast.makeText(this, "ISO15693 tag found!", Toast.LENGTH_LONG).show();
  else if(Ndef.get(tag) != null)
    Toast.makeText(this, "Android Beam message received!", Toast.LENGTH_LONG).show();
  else
    Toast.makeText(this, "Unknown tag type!", Toast.LENGTH_LONG).show(); // hypothetical...

    }

    There is no API defined in Android to communicate with an external reader. You could consider implementing peer-to-peer communication in the reader, using LLCP and SNEP (see NFC Forum for the specs).
