<p>The NFC API provides connectivity between NFC enabled devices.</p>
<p>Currently the API is supported on Android, and Linux using <a href="https://01.org/linux-nfc">Neard</a> v0.14 or later.</p>
<a name="overview"></a>
<h2 id="overview">Overview</h2>
<p>NFC is an extremely short-range (less than 20 centimeters) wireless technology and has a maximum transfer rate of 424 kbit/s. NFC is ideal for transferring small packets of data when two devices are touched together.</p>
<p>The NFC API provides APIs for interacting with NFC Forum Tags and NFC Forum Devices, including target detection and loss, registering NDEF message handlers, reading and writing NDEF messages on NFC Forum Tags and sending tag specific commands.</p>
<a name="getting-started"></a>
<h2 id="getting-started">Getting Started</h2>
<p>To use the C++ library in your application, add the following configuration option to your <code>.pro</code> file:</p>
<pre class="cpp">
QT += nfc
</pre>
<p>To use the classes of the module in your application you need the following import statement in your <code>.qml</code> file:</p>
<pre class="qml">
import QtNfc 5.2
</pre>
