requests this to include only the WPS attributes; NDEF parameter
requests additional NDEF encapsulation to be included). This data needs
to be written to an NFC tag with an external program. Once written, the
NFC configuration token can be used to touch an NFC interface on a
station to provision the credentials needed to access the network.
