A user terminal comprising: i) a display module comprising a display screen and an interface circuitry for receiving a user input; and ii) a magnetic stripe reader configured to detect a magnetic secure transmission (MST) signal received by the user terminal and, in response to the detection, to launch a real-time application in the user terminal. In one embodiment, the real-time application displays a message on the display module of the user terminal. In another embodiment, the real-time application transmits data to a third-party vendor associated with the MST signal.
