RFID technology has a wide range of applications in the field of smart transportation. It can achieve automatic vehicle authentication and tracking, thereby improving the safety and efficiency of road traffic. For example, through dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the radio frequency antenna of the toll station, it is possible for the vehicle to pay the toll without stopping at the toll station. In addition, RFID technology can also be used for data collection, bus cards, parking recognition, toll collection, taxi management, bus hub management, railway locomotive recognition, air traffic control, passenger ticket recognition, and luggage tracking.
