摘要: The device, and a respective system, comprises a microcontroller for signal processing and an interface controller for communicating with an IC card, the interface controller being coupled between the microcontroller and the IC card. According to the invention, the device comprises a reset button for resetting the microcontroller in case of a malfunction, the reset button being accessible to a customer, and a reset signal from the reset button simulates an IC card extraction or a card supply voltage shut down. In a special embodiment, the reset signal from the reset button is applied to the microcontroller and to the interface controller, and the signal from the reset button resetting the microcontroller is delayed by a delay circuit with respect to the signal, which resets the interface controller. The signal from the reset button is advantageously combined with the signal from a card presence contact via a logical OR-combination, and then coupled to a card presence input of the interface controller.
