Many business and commercial units, industrial and gated areas and corporate houses strive hard and spend much to ensure their properties have the appropriate design, state-of-the-art installations, and latest control systems and softwarefrom the security point of view.However, oftenthe entry pointsto these areas remain vulnerable due to deployment of basic access control methods, therebycompromising the security of the premises.

This is where a synergistic approach of combining technology with physical barriers –connecting Ultra High Frequency (UHF) readers to Boom Barriers enhances access control by preventing unauthorized entry.

What is UHF Technology?

Ultra High Frequency (UHF) refers to the Radio Frequency Identification (RFID) range between 300 MHz and 3 GHz. The short wavelength makes them more effective for long-range credential reading of vehicles and ideal for access control and security.

UHF tags can be attached as windshield cards on vehicles to enable automatic vehicle identification, improve access control and facilitate convenient entry/exit of vehicles.

A UHF-RFID system for vehicular entrance functions through a Reader to read and transmit signals, Access Control System, Tag and Carrier. When a vehicle with a UHF card is identified and verified, the reader then activates the output to open the boom barrier or access barrier and permit access. Thus, vehicle access can be managed through specific user-defined criteria, especially at strategic points where authorized entry is stipulated.

Here is a snapshot of the benefits of UHF in access control:

Contactless Authorization

Employing a UHF access control readermakes possible convenient vehicle movement and vehicle monitoring without physically deploying a guard. Windshield cards allow quick smooth access while maintaining zero contact.

A unique tamper proof RFID tag on each vehicle enhances safety. The reader identifies moving targets even at a distance with accuracy. Dirty or damaged number plates do not affect vehicle identification, as it would in case a physical guard was scanning. These are especially useful in logistics and warehouseswhere there is constant vehicle movement. Thus, bolster security sans additional costs of deploying a guard.

Seamless Integration and Customization

Agile software development kits in UHF readersaid in easy integration with existing access control systems. In corporate sectors, customization is possible to initiate access differentiation for regular vehicles, such as those of employees, to allow faster entry and exit.

UHF access control systems even allow pre-determining timings – for instance access restriction on weekends, holidays or during non-office hours. This level of customization provides high levels of security and curbs unauthorized access.

Convenient Parking Management

UHF-enabled access control systems are ideal for parking area access as it offers no-pause entry so tagged vehicles do not have to wait in line. For unmanned parking areas, a UHF reader helps to check the entry of unauthorized vehicles.

With the convenience and enhanced security that it offers, UHF access control systems for vehicle identification are steadily gaining popularity. The advancement of technology and the Internet of Things (IoT) has led to increase in applications and this will witness more developments in the years ahead.
