NFC Adapter

NFC Adapter provides access to the NFC device to perform device related operations.

    All properties and methods should be used after activate. Besides supported and isActive.
## Enabling the API
In order to use this API you must include the following extension in your `build.yml`
        extensions: ["nfc"]

<div class="alert alert-warning"><table>
<td><i class="icon-warning-sign icon-2x"></i></td>
<td>If you are building a Windows Mobile or Windows CE app with this API, you must set your app_type as "rhoelements" in your build.yml as shown [here](../guide/build_config#other-build-time-settings).</td>
</table></div>
