1 Introduction 
EFP (EasyFuel Plus) is an automated refueling system based on wireless 
communication between the system components. 
The system utilizes 13.56MHz proximity technology for interfacing between the 
vehicle and the fuel dispenser and longer range UHF communication for wireless 
interfacing to the EF Site Controller which is mounted in the site office 
The new RFN (RF Nozzle) unit, together with the new EF passive RFID vehicle tag, is 
OTI's latest addition to the EFP Family which also includes: 
 
EF-SC (Site Controller) 
The Site Controller is an RF transceiver, mounted in the site office, serving as 
an interface between the EFP system and the station refueling control system. It 
operates at 433MHz or 902-928MHz frequency ranges, depending on the 
locally allocated frequency slots. 
 
EF-VID (Vehicle IDentification) vehicle tag 
The VID is a microcontroller based in-vehicle device, utilizing vicinity range 
receiver for reading the NID (Nozzle IDentification) signal and UHF 
transceiver for communication with the Site Controller. It communicates to the 
SC the combined information of the vehicle data and the nozzle ID so as to 
enable proper refueling control. The vehicle data may include more 
sophisticated data elements like the odometer reading. The EF VID derives its 
power from the vehicle battery. 
 
NID (Nozzle IDentification) 
The NID is  a self-contained, battery operated, very low power 13.56MHz RF 
transmitter that slips over the fuel nozzle spout. The NID identifies the nozzle 
ID to the VID. 
 
Passive RFID vehicle tag 
The new passive RFID vehicle tag enables the RFN to read the vehicle basic ID 
information and to transfer the combined information of the vehicle and the 
nozzle ID data to the SC so as to enable proper refueling control. This way the 
use of VID may be avoided unless more sophisticated vehicle information is 
required as mentioned above.
