We have DEVELOPED our very own RFID tag reader that attaches to your CURRENT fuel dispensing nozzle! When you insert the nozzle into the vehicles inlet pipe in order to dispense diesel it will read our chip that is installed in the inlet pipe and immediately identify the correct vehicle. It will know from the chip what the maximum tank capacity is and will never dispense more liters than the tank capacity. We are currently working on integrating a tracking device that won't allow dispensing if the vehicle is not in the pumps geofence area as well as automatically pull in the tracker's mileage reading and provide you with the vehicle's instant consumption. If the consumption is out of allowed parameters, you will receive an email alert immediately informing you that something is suspect! TAKE BACK CONTROL OF YOUR VEHICLE DIESEL USAGE!
