Fuel dispenser user interface

摘要

A user interface for a fuel dispenser has a display, a display controller, and control circuitry. The control circuitry includes a processing device, memory, and at least one microswitch. The display controller and the control circuitry are positioned such that the microswitch connects the control circuitry to the display controller. The microswitch is activated if the control circuitry is separated from the display controller. Activation of the microswitch causes any sensitive information stored by the control circuitry to be erased. In one aspect, separation of the display controller from the control circuitry is the only manner by which the processing device and/or the memory may be accessed.

主权项

1. A user interface for a fuel dispenser adapted to handle sensitive information, the user interface comprising:
a display board; a display operatively connected to the display board and overlaying a first portion of the display board; a keypad interface overlaying a second portion of the display board, said keypad interface having a plurality of physical buttons depressible by a user; control circuitry comprising a processor and memory together operative to handle sensitive customer information, said control circuitry further comprising a first trigger, wherein the control circuitry is located between the second portion of the display board and the keypad interface so that the first trigger is connected to the display. board and is operative to detect separation of said display board from said control circuitry, such that access to the control circuitry for tampering purposes will be impeded by the display board and the keypad interface; and a frame, wherein the display and the control circuitry are mounted to the frame; and wherein a second trigger operatively connects the control circuitry to the frame and activation of the second trigger causes sensitive information stored in the memory to be erased.
