title: NFC tags read/write operations
body: <ol>
  <li><p>I would like to know which protocol is used for the read/write operations to the NFC tags are used. According to my understanding after the tag is placed on the NFC reader, it is powered and set to the ready state. Then the ‘application’ protocol for read/write operation is used. The exact format and the content of commands used for read/write is not specified in ISO 14443 and it is dependent on a tag hardware/manufacturer and will be different for </p>
  
  <ul>
  <li>FeliCa</li>
  <li>Mifare</li>
  <li>Innovision</li>
  <li>etc tags</li>
  </ul></li>
  </ol>
  
  <p>so there is no way how to handle NFC tags read/write operations with the single implementation.</p>
  
  <ol start="2">
  <li>Are there any tags, which supports the APDU 7816-4 commands for read/write operations?</li>
  </ol>
