+
+<p>Provides classes that manage the NFC functionality.</p>
+
+<p>The NFC functionality is related to Near Field Communication.</p>
+
+<p>The NFC APIs let applications:</p>
+<ul>
+  <li>Scan for remote NFC targets (NFC Tag or NFC Peer)</li>
+  <li>Transfer raw data to and from remote NFC targets (NFC Tags or NFC Peer)</li>
+  <li>Read/Write NDEF data from/to remote NFC targets (NFC Tags)</li>
+  <li>Establish LLCP connection with a remote NFC target (NFC Peer with LLCP support)</li>
+  <li>Exchange data with a remote NFC target through LLCP services (NFC Peer with LLCP support)</li>
+  <li>Be notified of transactions on the local Secure Element by an external NFC reader</li>
+</ul>
+
+
+<h1>Setting Up NFC</h1>
+
+<p>
+Before an application can use the NFC feature, it needs to check if NFC is
+supported on the device by getting an instance of the
+{@link com.trustedlogic.trustednfc.android.NfcManager} class.
+</p>
+
+<pre>
+	NfcManager mNfcManager = (NfcManager) getSystemService(Context.NFC_SERVICE);
+	if (mNfcManager == null) {
+		// Device does not support NFC
+	}
+</pre>
+
+<p>
+An application can ensure that NFC is enabled.
+If not, an application with the needed permission can request that NFC be
+enabled.
+</p>
+
+<pre>
+	if (!mNfcManager.isEnabled) {
+		// NFC is currently disabled.
+		// Enable NFC.
+		mNfcManager.enable();
+	}
+</pre>
+
+<p>
+Before using the card emulation mode, an application can ensure that a secure
+element is selected ({@link com.trustedlogic.trustednfc.android.NfcManager#getSelectedSecureElement}).
+If not, an application with the needed permission can recover the list of
+available secure elements on the device
+({@link com.trustedlogic.trustednfc.android.NfcManager#getSecureElementList}) and select one
+({@link com.trustedlogic.trustednfc.android.NfcManager#selectSecureElement}).
+</p>
+
+<p>
+Before using the NFC feature, an application can configure the NFC device by
+calling {@link com.trustedlogic.trustednfc.android.NfcManager#setProperties}. This function allows:
+</p>
+<ul>
+  <li>Enabling/disabling the NFC device capabilities (RF types, baudrates,
+  NFCIP-1 mode and role...)</li>
+  <li>Settings the NFCIP-1 general bytes and the LLCP link parameters</li>
+</ul>
+<p>
+The setting properties can be customized according to the Device capabilities.
+The next table give the minimal set of properties supported by the Device.
+Depending on the implementation, the table may be completed.

+<h1>NFC Permissions</h1>
+
+<p>
+To change the NFC service settings such as enabling the NFC targets
+discovery or activating the secure element, an application must declare the
+NFC_ADMIN permission.
+</p>
+<p>
+To perform NFC raw communication with a remote NFC target in
+Reader/Write Mode or Peer-to-Peer Mode, an application must declare the NFC_RAW
+permission.
+</p>
+<p>
+To receive NDEF message or Secure Element intents, an application must declare
+the NFC_NOTIFY permission.
+</p>
+<p>
+To receive the LLCP link intent and perform an LLCP communication with a remote NFC target, an application must
+declare the NFC_LLCP permission.
+</p>
+
+

+use cases.

+
+<h1>Multiple Applications rules</h1>
+
+<p>
+Several LLCP sockets can be created by a single application or by multiple
+applications by calling {@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpSocket}, 
+{@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpConnectionlessSocket} or 
+{@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpServiceSocket}, provided the local SAP
+numbers are differents.
+</p>
+
+<p>
+Only one application can open a raw connection by calling 
+{@link com.trustedlogic.trustednfc.android.NfcManager#openTagConnection} or
+{@link com.trustedlogic.trustednfc.android.NfcManager#openP2pConnection}.
+While this application has not closed or cancelled its connection, any other
+application that attempts to open another raw connection will raise an
+exception.
+During an open connnection, the card emulation mode is always enabled and 
+applications are able to receive card emulation intents.
+</p>
+
+<p>
+When an application opens a tag connection by calling 
+{@link com.trustedlogic.trustednfc.android.NfcManager#openTagConnection}, this operation is exclusive, no NDEF message intent are
+broadcast while the connection is not closed or canceled.
+</p>
+
+<p>
+When an application opens a peer-to-peer connection by calling
+{@link com.trustedlogic.trustednfc.android.NfcManager#openP2pConnection}, this operation is exclusive, no LLCP intent are broadcast and LLCP sockets are
+disabled while the connection is not closed or canceled. 
+</p>
+
+
+<h1>NFC Tag types</h1>
+
+<p>
+The {@link com.trustedlogic.trustednfc.android.NfcTag} type returned by
+{@link com.trustedlogic.trustednfc.android.NfcTag#getType} indicates the set of
