How RFID Works in Cars
RFID tags are small electronic devices that contain a unique identification number. These tags use radio waves to communicate with RFID readers, which are installed in cars. RFID tags can be passive or active. Passive tags do not have their own power source and rely on the energy emitted by the RFID reader to transmit their data. Active tags, on the other hand, have their own power source and can transmit data over longer distances.
RFID readers are installed in cars and are used to read the data stored on RFID tags. These readers use radio waves to communicate with the RFID tags and can read data even when the tag is not in direct line of sight. The data collected by the RFID reader is then transmitted to a central computer system, which can be used to track the movement of the car.
When an RFID tag comes within range of an RFID reader, the reader sends out a radio signal that wakes up the tag. The tag then sends its unique identification number back to the reader, which is then transmitted to the central computer system. The data transmitted by the RFID tag can include information such as the make and model of the car, the date and time of the tag’s transmission, and the location of the car.
Overall, RFID technology provides a convenient and efficient way to track the movement of cars. It is commonly used in toll collection systems, parking lots, and other areas where it is important to know the whereabouts of cars. You can make modifications.
