Active RFID tags are powered by battery or permanent DC connection and provide a much increased read range. 

In the case of vehicle tracking, an RFID "puck" can be bolted to the underside of a car, and as the car rolls up a driveway, a reader beside or embedded in the drive picks up the tags ID and can open a gate, turn on lights if dark, and due to the fact that each RFID number is unique - even open the correct garage door!
