The difference between Semi-EPS and Full-EPS

15 February, 2024


Electronic Parking Systems (EPS) have significantly transformed the management of parking facilities, providing advanced solutions for efficient vehicle entry and exit. In this article, we delve into the distinctions between Semi-Electronic Parking Systems (Semi-EPS) and Fully Electronic Parking Systems (Full-EPS), drawing insights from comprehensive overviews. By exploring their features, operational procedures, and cost implications, we aim to provide a nuanced understanding of each system.


Semi-Electronic Parking Systems (Semi-EPS)


Semi-EPS offers significant cost savings by eliminating the need for expensive automated payment functionalities. With a manual payment process, drivers directly insert CashCards or swipe CEPAS cards into the Unified POS (UPOS) terminal, resulting in a more affordable implementation. This streamlined approach not only reduces initial setup costs but also ensures efficient operation without compromising on essential functionalities.


Operating Procedure of Semi-EPS:

  • Entry Point Operation
    1. The Ultra High Frequency (UHF) RFID system detects incoming vehicles, wirelessly reads IU identification, and records entry details.
    2. The barrier lifts for the vehicle to enter and lowers back into position after passage.
  • Exit Point Operation
    1. The Antenna detects approaching vehicles, reads IU unit ID, queries the database for parking charges, and displays the amount on an LED panel.
    2. Drivers manually insert CashCard/CEPAS card into the Unified POS (UPOS) terminal to make payment, and the barrier lifts upon a successful transaction.
    3. Vehicles belonging to season pass holders are effortlessly identified by the antenna through the scanning of their In-Vehicle Unit (IU), allowing them to proceed to exit without the need for manual payments.

Full-Electronic Parking Systems (Full-EPS)


Seamless Hands-Free Operation: Full-EPS allows vehicles with In-Vehicle Units (IUs) to effortlessly enter and exit parking areas without requiring manual interventions.


Operating Procedure of Full-EPS:

  • Entry Point Operation
    1. The EPS Antenna detects the IU identification ID, records entry details, and lifts the physical barrier for the vehicle to enter.
    2. Long Range RFID Antenna wirelessly communicates with the IU, registering the vehicle's entry time in the EPS system.
  • Exit Point Operation
    1. The Long Range RFID Antenna reads IU identification at the exit, cross-references it with entry records, and computes parking charges.
    2. An LED display shows charges, and a wireless signal is transmitted to the IU for payment.
    3. Upon successful deduction, the barrier lifts, facilitating the vehicle's exit.
    4. Automatic exemption of season pass holders from deductions upon exit.


In the ever-evolving landscape of electronic parking solutions, choosing between Semi-EPS and Full-EPS depends on factors such as budget considerations, traffic volume, and desired automation levels. While Full-EPS provides a hands-free and efficient experience, Semi-EPS offers a cost-effective alternative without compromising essential functionalities. Understanding these distinctions ensures informed decision-making for parking facility management and a seamless experience for drivers in bustling parking facilities.
