<p>ISO/IEC 14443-3:2011 describes:</p>
<ul>
<li>polling for proximity cards or objects (PICCs) entering the field of a proximity coupling device (PCD);</li>
<li>the byte format, the frames and timing used during the initial phase of communication between PCDs and PICCs;</li>
<li>the initial Request and Answer to Request command content;</li>
<li>methods to detect and communicate with one PICC among several PICCs (anticollision);</li>
<li>other parameters required to initialize communications between a PICC and PCD;</li>
<li>optional means to ease and speed up the selection of one PICC among several PICCs based on application criteria.</li>
</ul>
<p>Protocol and commands used by higher layers and by applications and which are used after the initial phase are described in ISO/IEC 14443-4.</p>
<p>ISO/IEC 14443-3:2011 is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2).</p>
