title: Reading NFC Tag types "android.nfc.tech.NfcV" and "android.nfc.tech.NdefFormatable" with React Native
body: <p>I am trying to read from a Bloodsugar Meter using NFC, right now on an Android, haven't tried iOS yet (don't have a phone with NFC).</p>
  
  <p>I am using <strong>react-native-nfc-manager</strong> as library and the example that comes with it:
  <a href="https://github.com/whitedogg13/react-native-nfc-manager" rel="nofollow noreferrer">https://github.com/whitedogg13/react-native-nfc-manager</a></p>
  
  <p>I am receiving this tag:</p>
  
  <pre><code>{ "techTypes":["android.nfc.tech.NfcV","android.nfc.tech.NdefFormatable"], "id":"87C5280D002602E0"}
  </code></pre>
  
  <p>I can see that NfcV is covered in this library, but how do I read it as that type?</p>
  
  <p>I am following the example so I haven't set anything in my manifest or my build.gradle. I have linked it and it is working, but im missing the last part it seems.</p>
  
  <p>By following the example it looks like I am supposed to use a method like this:</p>
  
  <pre><code>_parseText = (tag) =&gt; {
      try {
          if (Ndef.isType(tag.ndefMessage[0], Ndef.TNF_WELL_KNOWN, Ndef.RTD_TEXT)) {
              return Ndef.text.decodePayload(tag.ndefMessage[0].payload);
          }
      } catch (e) {
          console.log(e);
      }
      return null;
  }
  </code></pre>
  
  <p>But my tag doesn't have a <code>ndefMessage[0]</code>.</p>
