body: <p>I am using the following command to read a binary block from a Mifare Ultralight tag: <code>FF B0 00 01 04</code></p>
  
  <p>But now I want to exact the NDEF message stored in that Mifare Ultralight tag using an ACR1252 NFC reader. Which command do I have to use to get the full NDEF message? On which position in the tag is the NDEF message stored?</p>
