How RFID Technology Contributes to Vehicle and People Access Control?

Over the last few decades, RFID or radio frequency identification has become an integral part of the security industry. But what is RFID, and how does it contribute to the vehicle and people access control?

RFID depends on electromagnetic fields to automatically pinpoint and track objects. It has attained widespread recognition in different markets – from healthcare to retail. Almost all RFID systems have a microchip, a tag or antenna, a reader, and an access control server. They cross-reference the information stored in the tag with their own database. If the information matches, access is granted.

RFID Frequencies

RFID incorporates different frequency levels that determine its reading range. The higher the frequency, the longer the reading range. A few common frequency ranges are as follows:

  • High Frequency – 13.56 MHz
  • Ultra-High Frequency – 860-980 MHz
  • Microwave Frequency – 2.45 GHz
  • Low Frequency – 120-150 kHz

The experts providing RFID for inventory said high-frequency ranges are used for people access. The reading distance is between 10cm to 1m. Ultra-high frequency ranges are predominantly utilized in logistics for tracking products and parcels within the manufacturing and distribution procedures. It is perfect for access control to gated sites. If the premises deal with taxis, buses, trucks, and vehicles that guarantee operational continuity, one must opt for microwave frequencies.

Vehicle Access Control

RFID tags are placed on buses, cars, taxis, etc., so they can gain secure access to a site. When the vehicle approaches the site, the reader captivates the signal sent by the tag, identifies the driver, and compares the code with the database. If the vehicle is identified, the gates open.

RFID’s vehicle access control has applications in plenty of scenarios. For instance, parking lots can use RFID tags to read parking permits and generate an alert if the permit has expired. It streamlines workflow while improving security.

People Access Control

Access control solutions have evolved to support varied kinds of physical credentials. Also known as passcards, these credentials have now taken the form of a barcode, magnetic stripe, smart card, etc.

An RFID tag is placed within a card or key fob. It is picked up by a compatible reader lying at a working range. The range relies on the frequency used in tag and reader. Such technology allowed organizations to grant hassle-free, simple access. People just have to present a card or badge.

Based on the frequency, the readers can read the ID cards from two meters. They are thus used extensively in hospitals.

Advantages of RFID is Vehicle and People Access Control

1. A Centralized Outlook Toward Security

The experts offering top-notch RFID inventory management system said long-range RFID is a comprehensive vehicle and people solution. People can now reach the sites required without touching any surface. They can access the building and their car with the help of a card.

2. Decreased Virus Spread

The coronavirus outbreak has revealed the demand for a long-range access system to reduce unnecessary contact with devices. Access control systems that use long-range RFID decrease the spread of viruses and protect both employees and visitors.

3. Zero Unwanted Costs and Amazing ROI

Hiring guards to observe access to parking facilities and associated premises is quite expensive, specifically considering other factors that can increase company expenses like human error and the additional time it takes for a guard to check if a visitor is authorized. Since RFID can grant access to several people and vehicles simultaneously, it reduces unwanted costs and improves the ROI.

Gone are those days when securing the premises and ensuring safe access needed abundant time and workforce. Thanks to RFID, businesses can now provide an integrated and affordable approach to security with little to no complications.
