FUEL DISPENSER USER INTERFACE

A user interface (40) for a fuel dispenser (10) comprising a display (50), a display controller (200), and control circuitry (204). The control circuitry (204) comprises a processing device (210), memory (300), and at least one microswitch (214). The display controller (200) and the control circuitry (204) are positioned such that the microswitch (214) connects the control circuitry (204) to the display controller (200). The microswitch (214) is activated if the control circuit1y (204) is separated from the display controller (200). Activation of the microswitch (214) causes any sensitive information stored by the control circuitiy (204) to be erased. In one aspect, separation of the display controller (200) from the control circuitry (204) is the only manner by which the processing device (210) and/or the memory (300) may be accessed.
