ZipCar has an elaborate fleet card setup. I remember having to type in the current odometer value, and some other identifiers, on the gas pump keypad. Never seen something like that before.
I worked as a delivery driver for an auto parts store in ~2010. We had the same thing, but the card was tied to the vehicle (the card was literally attached to the vehicle's key) so we didn't have to type in the vehicle ID.
