title: APDU command read contact smart card id data
body: <p>I have a contact smart card reader following <code>ISO-7816</code> standard and I have a smart card id with ATR: </p>
  
  <pre><code>3B 7F 96 00 00 80 31 80 65 55 85 03 00 EF 12 41 40 82 90 00
  </code></pre>
  
  <p>My goal is to get the data saved to card like civil id number, DOB etc so I tried to select the MF file using the following command:</p>
  
  <pre><code>APDU: 00 A4 00 00 02 3F 00 
  
  RAPDU: 6F 1C 83 02 3F 00 8C 03 06 E4 E4 9C 03 06 E4 E4 84 0C A0 00 00 00 18 40 00 00 01 63 42 00 90 00
  </code></pre>
  
  <p>as I read that commands is executed successfully as it returns <code>9000</code> as SW1 SW2 fields and I know the part of the returned message before the 9000 is data but my problem here that I don't know what is data represent or how to use this data to get the id stored information that I need.</p>
