This interface provides a notification to the application when external reader is connected or disconnected for Secure Element in card emulation mode. The notification indicates that the external reader might changed the data in the Secure Element, and the application which is listening the notification need to retrieve the data from the Secure Element to e.g. updata the UI. How to retrieve data from the Secure Element is not in the scope of this API, but should be done with APDU Qt API, please refer to APDU Qt API about how to access the Secure Element data.
A external reader is a NFC Initiator that requests data from the device when the device works as a NFC Target in card emulation mode. For more detailed information about NFC Initiator and Target, please refer to 'NFC Digital Protocol' and 'NFC Activity' technical specifications.
// Create a instance of XQNfcSeTransactionProvider
m_nfcSeTransactionProvider = new XQNfcSeTransactionProvider();
// Create a instance of SE transaction listener, the listener class
// MySeTransactionListener is defined by the API user and it has two slots
// onExternalReaderConnected() and onExternalReaderDisconnected() implemented
// to handle the externalReaderConnected() and externalReaderDisconnected() signals.
m_transactionListener = new MySeTransactionListener();
// Connect the listener's slots with the signals, after external reader
// connected/disconnected, the slots will be invoked, the listener should
// implement the data retrieving from the secure element using APDU Qt API
// in the slots.

This signal is emitted when the device has been connected to an external reader. It is emitted after EVT_TRANSACTION received. Please refer to Technical Specification "ETSI TS 102 622" for more detailed infomation about EVT_TRANSACTION. The listener should implement the slot and connect its slot with this signal to receive the notification.
