    Abstract: A dispensing system (10) that utilizes radio frequencies identification capabilities in a service station environment to reliably and accurately detect an on-board vapor recovery (ORVR) system in a vehicle (26). The dispensing system (10) includes a vapor recovery system (33) for recovering fuel vapors responsive to a fuel being dispensed. The vapor recovery system (33) has a disabling mechanism (42) for selectively preventing its operation. The dispensing system (10) also includes an antenna (22A, 22B, 24A, 24B) for detecting a radio frequency signal from a transmitter (23 or 25) in a vehicle (26). The radio frequency signal may be a single bit indicating that the vehicle (26) has the ORVR system, or may include additional bits indicating a type of fuel to be dispensed. When the transmitter (23 or 25) is within a predetermined distance from the antenna (22A, 22B, 24A, 24B), a controller (20) receives the radio frequency signal from the antenna (22A, 22B, 24a, 24B) and asserts a disable signal (41). The disabling mechanism, responsive to the asserted disable signal (41), prevents the vapor recovery system (33) from operating and thereby eliminates any unwanted accumulation of air.
