Patent attributes
A fuel truck is used to deliver fuel to vehicles parked at one or more locations. While the fuel truck is servicing vehicles, a user of the fuel truck uses a mobile device to assist in the management of fuel delivery. Specifically, each vehicle being serviced has a tag that is a capable of being read by the mobile device. The tag communicates information that identifies the vehicle, and the mobile device communicates with a meter on the fuel truck to track how much fuel is delivered to the identified vehicle. The mobile device also controls the meter such that fuel is allowed to flow only when the mobile device is aware of which vehicle is receiving the fuel. Thus, over time, the mobile device is able to track accurately which vehicle is receiving fuel so that the amount of fuel delivered to each vehicle can be precisely determined.
