Detailed Description
The NearField type can be used to read NDEF messages from NFC Forum tags. Set the filter and orderMatch properties to match the required NDEF messages. Once an NDEF message is successfully read from a tag the messageRecords property is updated.
NearField { filter: [ NdefFilter { type: "U"; typeNameFormat: NdefRecord.NfcRtd; minimum: 1; maximum: 1 } ] orderMatch: false onMessageRecordsChanged: displayMessage() }

Property Documentation
filter : list<NdefFilter> |
This property holds the NDEF filter constraints. The messageRecords property will only be set to NDEF messages which match the filter. If no filter is set, a message handler for all NDEF messages will be registered.
messageRecords : list<NdefRecord> |
This property contains the list of NDEF records in the last NDEF message read.
This property indicates whether the order of records should be taken into account when matching messages.
