RFID (Radio Frequency Identification) is a wireless technology that uses electromagnetic fields to automatically identify and track tags attached to objects — in this case, vehicles.
Components of an RFID Vehicle Identification System
RFID Tags/Stickers ( Transponders )
Attached to the vehicle ( principally on the windshield for best performance )
Types :
Passive tags: No internal power source; activated by the reader signal.
Active tags: Battery-powered; longer range and data capabilities.
RFID Readers ( Transceivers )
Installed at entry/exit points (gates, toll booths, parking lots).
Communicate with the tag/sticker to retrieve vehicle ID data.
Antenna
Facilitate communication between the reader and tag/sticker.
Software/Backend System:
Processes RFID data for:
Vehicle identification
Access control
Toll collection
Vehicle tracking/logs
Integration with security, billing, or fleet systems
How it Works
Vehicle approaches a checkpoint ( e.g. gate or toll plaza ).
RFID reader ( transceiver ) sends a signal and detects the vehicle’s tag/sticker.
The tag/sticker transmits stored data ( a unique ID ).
The system verifies the ID and performs an action ( e.g. opens a gate, logs the time ).
