\title Supported NFC Features
\ingroup connectivity-nfc
\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.
