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()
    }

QNearFieldManager::registerNdefMessageHandler()


messageRecords : list<NdefRecord>

This property contains the list of NDEF records in the last NDEF message read.


orderMatch : bool

This property indicates whether the order of records should be taken into account when matching messages.
