Abstract: One embodiment is a hybrid forecourt controller (FCC) for a fuel-dispensing facility having forecourt devices and in-store systems. The hybrid FCC has a closed sub-system communicating with and controlling operations of the forecourt devices and an open sub-system communicating with and controlling operations of the in-store systems. The closed sub-system communicates with the open sub-system to enable the forecourt devices and the in-store systems to operate together to support operations of the fuel-dispensing facility. The closed sub-system prevents third parties from modifying any of the closed operating system and the closed software applications corresponding to the forecourt devices of the closed sub-system, while the open sub-system enables third parties to modify any of the open operating system and the open software applications corresponding to the in-store systems of the open sub-system.
