Access Control Solutions are important in managing the flow of Vehicles and People. Access Control devices such as RFID readers, Biometric Terminals, and ANPR cameras to ensure only authorized individuals or vehicles can access a particular location.
In this article, we will discuss how to choose a correct Access Control System to control the on different entry points in a facility, including Automatic doors, Electromagnetic locks, Lift access, Turnstiles, and Barrier Gates.
RFID (Radio Frequency Identification) reader is a device that uses radio waves to communicate with RFID tags, also known as transponders, to read or write data. There are several types of RFID readers available in the market, categorized based on the frequency they use.
The Low-frequency RFID reader operates between 125 to 134 kHz frequency range, is the oldest and the most commonly used RFID technology. This type of reader is suitable for short-range applications with reading range of up to 10 cm. LF RFID tags are commonly used for door access control systems.
The High-frequency RFID reader operates between 13.56 MHz frequency range and has a shorter wavelength, which results in a shorter read range compared to LF RFID readers. However, HF RFID readers offer better data transfer rates and are suitable for applications that require high-speed data transfer such as contactless payment, ticketing, and inventory management systems.
The Ultra High-frequency RFID reader operates between 919 to 923 MHz frequency range and with longest read range. UHF RFID readers are suitable for long-range applications and can read tags up to 6 meters away. This makes them ideal for tracking assets such as vehicles, in guard house access and supply chain management systems.
