Method Detail

readerSessionDidInvalidateWithError

void readerSessionDidInvalidateWithError(NFCVASReaderSession session,
                                         NSError error)

void readerSessionDidReceiveVASResponses(NFCVASReaderSession session,
                                         NSArray<? extends NFCVASResponse> responses)

readerSession:didReceiveVASResponses:

Gets called when the reader completes the requested VAS transaction. Polling is automatically restarted once the detected tag is removed from the reader's read range.

Parameters:

session - The session object used for tag detection.

responses - Array of @link NFCVASResponse @link/ objects. The order of the response objects follows the sequence of GET VAS DATA sent by the reader session.

readerSessionDidBecomeActive

default void readerSessionDidBecomeActive(NFCVASReaderSession session)

readerSessionDidBecomeActive:

Gets called when the NFC reader session has become active. RF is enabled and reader is scanning for VAS tags. The @link readerSession:didReceiveVASResponses: @link/ will be called when a VAS transaction is completed.

Parameters:
