Transponder distinction in a fueling environment

Abstract

The present invention solves these problems by providing a fueling system capable of distinguishing between types of transponders based on the type of signals transmitted or information transmitted therein. Based on the type of transponder, the system may control dispenser functions accordingly. For example, certain applications may allow transponders carried on a person to be moved about the fueling environment during a fueling operation, but stop fueling and provide warning or instructional information if a vehicle mounted transponder begins or starts to move during the fueling operation. The fueling system may use many various techniques to determine transponder movement within the fueling environment, and in particular, with respect to the fuel dispenser at which the fueling operation is taking place. The system may simply determine a relative change in the proximity of the transponder with respect to the dispenser, a change in location with respect to the dispenser or simply receiving data from the vehicle transmitter or other remote source that the vehicle is moving or preparing to move. Preferably, in the latter situation, the vehicle transmitter is associated with a vehicle control system capable of sending information to the transmitter indicative of the vehicle being started, placed in gear and/or actually moving. A global positioning system may be used to interact through the vehicle or part of the fueling system to provide information on the vehicle movement and location.
