RFID stands for Radio Frequency IDentification. It is a tag that sends information to an RFID reader whenever the tag passes by it. It has mini-antennas, the conductive foils in the tag, to receive energy in the form of radio waves. This received energy, a very small amount, is sufficient to power a microchip—the black part in the tag–and reply with a valid code to identify the specific tag. A computer then checks for the account information associated with the tag, and in the case of RFID use in toll gates, charge payment accordingly.
There’s a catch though. You can’t place this tag just about anywhere. For it to work, it must be placed on a non-metallic surface so the tag’s antenna can work properly. It will not work when placed on a car’s metal body or windshield with metallic tints. This means that in the case of an EcoSport, your option is limited to placing the tag on the windshield (with non-metallic tints), or the headlights. However, it is best to stick the tag on the headlight assembly. Why? Because the headlight is at the front most part of the vehicle, i.e., as you approach the sensor, a tag on the headlights will be detected by the sensor first as it comes within range, compared to a tag placed on the windshield.
Having an RFID tag installed is as simple as driving to a “reloading station” and wait a few moments for a staff to place the small transceiver on a non-metallic part of your vehicle (so simple and easy you don’t even have to leave your vehicle) :)
