Abstract: A system and method for gas pump or carwash environments which allows new applications to be added to established systems, having a computing system, software techniques, and hardware or software communications interfaces. Various embodiments include methods of separation and interception and the software techniques. One implementation includes separating a first application from an equipped device by interposing a bridge; intercepting, with the bridge, downstream communications to the equipped device from the first application; using the bridge, accepting downstream communications to the equipped device from a second application; with the bridge, locking communications with the equipped device to one of the first application and the second application; and unlocking the communications with the equipped device in response to receiving a status from the equipped device.
