Detailed Description

The NearField element is part of the QtMobility.connectivity 1.2 module.

The NearField element 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: "urn:nfc:wkt:U"; minimum: 1; maximum: 1 } ]
     orderMatch: false

     onMessageRecordsChanged: displayMessage()
 }
