Understanding UHF Car Park Cards: Applications
Ultra-High Frequency (UHF) car park cards are widely used in modern parking systems for their convenience, long-range detection, and fast processing. These cards operate at frequencies between 860 MHz to 960 MHz, allowing vehicles to enter and exit parking facilities without physical contact.
While UHF cards enhance efficiency, they also pose security risks—particularly cloning. In this post, we’ll explore how UHF car park cards work, their applications, and the risks associated with cloning them.
How UHF Car Park Cards Work
UHF RFID (Radio Frequency Identification) cards communicate with readers via electromagnetic waves. Here’s a simplified breakdown:
Card Issuance – Each card has a unique ID or encrypted data linked to a user or vehicle.
Reader Detection – When a car approaches, the UHF reader sends a signal to the card.
Data Transmission – The card responds with its stored information, granting or denying access.
Unlike LF (Low Frequency, 125 kHz) or HF (High Frequency, 13.56 MHz) cards, UHF cards can be read from several meters away, making them ideal for automated parking systems.
Common Applications of UHF Car Park Cards
Automated Parking Systems – Allows seamless entry/exit without stopping.
Gated Communities & Offices – Restricts unauthorized vehicle access.
Toll & Paid Parking – Enables cashless transactions with prepaid or subscription-based cards.
Fleet Management – Tracks company vehicles entering/exiting designated areas.
