Scenarios
Vehicle with passive RFID tag:
When the nozzle is inserted into the vehicle refueling inlet the RFN reads data from the
passive RFID vehicle tag and transmits it together with its own identity to the site
controller. Fuel is dispensed once the transaction is authorized. Fuel is dispensed as
long as the RF Nozzle detects the presence of the passive RFID tag. If the nozzle is
retracted from the refueling inlet so that the RFID tag is not detected the RFN informs
the system to stop dispensing fuel.
