+\inmodule QtNfc
+\brief Summary of supported NFC features on different platforms.
+
+Qt NFC provides two options for reading and writing the data. These options are
+reflected in the \l {QNearFieldTarget::}{AccessMethod} enum.
+
+\list
+  \li \l {QNearFieldTarget::}{NdefAccess} - using NDEF messages via
+      \l {QNearFieldTarget::}{readNdefMessages()} and
+      \l {QNearFieldTarget::}{writeNdefMessages()}.
+  \li \l {QNearFieldTarget::}{TagTypeSpecificAccess} - sending custom commands
+      using \l {QNearFieldTarget::}{sendCommand()} and getting the results via
+      \l {QNearFieldTarget::}{requestResponse()}.
+\endlist
+
+\l {QNearFieldTarget::}{TagTypeSpecificAccess} implies that the
+user might need to send different data based on the NFC Tag Type. Tag types
+recognized by Qt NFC are defined in the \l {QNearFieldTarget::}{Type} enum.
+
+Qt NFC support for different access methods and tag types varies depending on
+the platform. The table below shows currently supported subsets of features
+for every platform.
