Abstract
A fraud detection system within a fuel dispenser includes the ability to measure the amount of fuel dispensed through the fuel dispenser. The measurement is compared to a value independently created representing what the amount of fuel dispensed should approximate. If the values are not comparable, an alarm may be generated to indicate that the fuel dispenser has been modified to perpetrate fraud upon the customers. In particular, a reference used in the comparison is created bearing on a vapor recovery system associated with the fuel dispenser. The vapor recovery system, by its collection of vapor during the fueling transaction provides an independent number related to the amount of fuel actually dispensed.
