Technical Principles

RFID (Radio Frequency Identification) parking systems utilize wireless radio frequency identification to enable non-contact data communication via electromagnetic fields.

The core workflow includes:

1. Tag Identification: Each vehicle is equipped with a passive/active RFID tag containing a unique EPC (Electronic Product Code) code.

2. RF Interaction: RFID readers at entry/exit points emit electromagnetic waves (e.g., 860–960 MHz UHF band) to power and activate the tags.

3. Data Transmission: Tags backscatter modulated signals to transmit vehicle ID data, achieving a read range of 3–12 meters.

4. Dynamic Verification: The backend system validates permissions in real-time against a database and triggers gate control signals.
