Abstract: A fleet fueling system may be implemented with controllers electronically interfacing with fuel dispensers at dispensing stations and communicating via a wide area network with one or more computing device implementing multiple subsystems. Hardware components and subsystems may be configured to avoid operating errors and provide end-to-end functionality, including one or more of: avoiding damage to movable readers that can collect information about assets positioned at fuel dispensing stations, selectively authorizing fuel to be dispensed based on the types and amount of fuel those assets are authorized to receive, quickly and reliably entering information about assets, providing analytics relating to fuel usage per asset, predicting future fuel needs at each of multiple fuel dispensing sites and scheduling fuel deliveries based on predicted needs, and detecting or correcting operating errors in the system.
