title: How can I read MifareClassic card with NFC Android?
body: <p>I am working with NFC Android programming and I want to read Mifare Classic cards.  Does anybody know how to read the sectors off such a card?</p>
  
  <p>My problem is the <code>transceive()</code> method. I don't know how to use it to read a sector 
  for example to read sector 1.</p>
  
  <p>Authentication method returns true which means that authentication is done. After authentication, sector should be ready for any IO action  but whenever i use readBlock() method or transceive() method, I get exception with  IOException("transceive failed"). 
  I can not find any example which uses the Mifare Classic, so i want to know if it is possible to read the Mifare Classic with this API or not.</p>
  
  <p>Kind Regards.</p>
