A system () and method () for reliable monitoring of secure application execution events is provided. The system can include a Near Field Communication (NFC) modem () for communicating transaction events of a secure contactless transaction () with a NFC reader (), a secure controller () for monitoring state transitions caused by the transaction events, and a mobile host communicatively coupled to the secure controller for receiving hardware event notifications of the state transitions. The secure controller can generate message using a hardware interrupt to a mobile host based on secure applet state transition monitoring by setting up the events flag such as a Transaction Completion Flag (TCF) () into an Events Status Register () to identify a status of a secure contactless transactions.
