title: How to check my NFC TAG ID (UID)?
body: <p>It is possible to know others NFC TAG ID when we used to the APK &amp; TAG each phones.
  For example,
  Phone A and B try to tag. Then Phone A can know Phone B's NFC TAG ID (4 Bytes - HEX).
  But I wanna know how to know my NFC TAG ID on my phone. Not used other phones.
  If you know any other information, please give me your advice on that.</p>
