Abstract: A system and method for obtaining manufacturer-signed content for use with manufacturer equipment is provided. Content is obtained at a merchant device for executing or presenting on manufacturer equipment. A signature is generated for the content based on a private key. The merchant device transmits the content and signature to a manufacturer server. The manufacturer server decrypts and authenticates the signature based on the private key or a corresponding public key. If authenticated, the manufacturer server re-signs the content with a manufacturer signature that allows the content to be presented or executed on manufacturer equipment.

Abstract: A user interface for a fuel dispenser comprising a display, a display controller, and control circuitry. The control circuitry comprises 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.
