What’s An RFID Access Control?

RFID access control utilizes radio frequency identification technology to manage and restrict entry to a facility or area. This system uses RFID readers [1] and tags (including key fobs, cards, and sometimes mobile devices) to grant or deny access based on predefined credentials.

Unlike traditional keys or access codes, RFID access control offers touchless entry, enhancing convenience and security. Automating entry permissions reduces the risk of unauthorized access, making it a cornerstone of modern security systems in various settings, from offices to residential buildings.

How To Choose the Best RFID For Access Control


When selecting an RFID access system, ensuring compatibility with your existing security infrastructure is crucial. The system should seamlessly integrate with other security measures, such as surveillance cameras and alarm systems.

Compatibility extends to the types of RFID tags and readers, ensuring they match the frequency and technology standard (like NFC for mobile access) used by your organization.

Security Issues

Security is paramount. Choose an RFID system with advanced encryption and protection against cloning or hacking.

Look for systems that provide dynamic or encrypted tags, which are much harder for potential intruders to replicate. Additionally, consider systems with multi-factor authentication for sensitive areas.


Depending on the application, you might need a system that can read tags from a few centimeters away (for door locks) or several meters (for vehicle access). The right choice depends on the specific use case and the layout of your premises.


As your organization grows, your RFID access control system should accommodate more users and additional access points without requiring a complete overhaul.

Look for systems that allow the easy addition of readers and tags and software that supports expanding access permissions and locations.


Finally, pricing plays a significant role in the decision-making process. While investing in a secure and reliable RFID door entry system is important, ensure that the cost aligns with your budget and provides value for money.

Consider the initial setup and hardware costs and any ongoing fees for subscription, software, updates, and maintenance.

How Does An RFID Tag Work?

An RFID tag stores data that an RFID reader can read through radio waves. This tag is part of a system that tracks and manages objects, people, or animals. When the tag comes into the vicinity of an RFID reader, it receives a signal, activating the tag.

The tag then transmits its stored data back to the reader. This interaction allows for seamless identification and tracking, making RFID technology invaluable in various applications, from access control systems to inventory management.

Types of RFID Tags


Active RFID tags are equipped with their power source, usually a battery, which allows them to transmit signals over longer distances, typically ranging from 20 meters up to several kilometers under clear conditions. Such a tag is ideal for tracking high-value goods over large areas, such as vehicles in a parking lot or equipment in a large warehouse.

The built-in battery enables active tags to broadcast their signal actively and supports additional features like sensors and larger memory capacities. However, their higher cost and limited battery life are considerations for potential users.


Passive RFID tags do not have their power source. Instead, they draw power from the reader’s signal to return their data. It limits their operational range to a few centimeters up to several meters, depending on the frequency and the environment.

The low cost, small size, and lack of battery requirement make passive tags suitable for a wide array of applications, including access cards, inventory labels, and tracking consumer goods. The limitations of passive RFID technology include a shorter read range and a lesser ability to penetrate materials than active tags.


Semi-passive, or hybrid, RFID tags feature a small battery that powers the tag’s electronics. This enhances signal strength and reliability without actively broadcasting a signal like their active counterparts. It allows for a greater read range than passive tags while maintaining a longer lifespan and lower cost than active tags.

Semi-passive tags are particularly useful in scenarios where consistent performance is needed despite environmental challenges, such as tracking assets in harsh conditions or where accurate, reliable detection over moderate distances is required.

What’s An RFID Reader?

An RFID reader is a device used to communicate with RFID tags to retrieve the stored data. It sends radio waves to activate the tag and read or write data. This interaction allows for identifying, tracking, and managing objects, animals, or people associated with the tag.

RFID readers are crucial components of RFID systems, playing a key role in various applications such as access control, inventory management, and security systems. Their ability to quickly and accurately gather information from RFID tags makes them indispensable in modern access control and security systems.

Types of RFID Readers


Fixed RFID readers are permanently installed at specific locations, such as doorways, entry gates, or conveyor belts. They continuously monitor tags within their read range, making them ideal for access control systems, asset tracking, and inventory management.

Fixed readers offer a hands-free operation and can manage multiple tags simultaneously, enhancing security and efficiency in environments like warehouses, offices, and retail stores. However, their stationary nature means they’re best suited for monitoring predefined areas.


Handheld RFID readers offer flexibility and mobility, allowing users to bring the reader to the tag. They are commonly used in inventory management, asset tracking, and field service applications where portability is essential.

Handheld readers are particularly useful when fixed readers cannot reach or spot-check specific items. Their versatility makes them a valuable tool for workers on the move, though their range and battery life can be limiting factors compared to fixed readers.


Integrated RFID readers are built into other devices, such as mobile phones, tablets, or other specialized equipment, combining RFID reading capabilities with the functionality of the host device. This integration allows for compact, versatile solutions that can leverage the connectivity and processing power of modern mobile devices.

Integrated readers are ideal for applications that require RFID functionality alongside other tasks, such as ticketing, point of sale, or personal identification. They offer a convenient, all-in-one approach but may need to improve range and performance compared to standalone readers.

3 RFID Frequency Bands

1. LH (Low Frequency)

Low Frequency (LF) RFID operates around 125 to 134 kHz. This frequency band is characterized by its short read range, typically less than 10 cm, making it suitable for applications requiring proximity.

LF RFID is commonly used in access control systems and animal tagging due to its ability to penetrate water and metal. Despite its limited range, LF RFID offers a reliable and secure method to manage access control in environments where interference is a concern.

2. HF (High Frequency)

High-frequency (HF) RFID operates at 13.56 MHz and offers a moderate read range of up to 1 meter. It is widely used in ticketing, payment systems, and data exchange applications. This frequency band [2] is favored for NFC (Near Field Communication) access control systems, balancing range, and security.

HF systems are ideal for environments where a greater read range than LF is needed but without the requirement for the extended range provided by UHF.

3. UHF (Ultra High Frequency)

Ultra-high-frequency (UHF) RFID operates between 860 and 960 MHz and can achieve read ranges of up to 12 meters under optimal conditions. It is known for its high data transfer rate and the ability to read multiple tags simultaneously, making it ideal for inventory and supply chain management.

UHF systems are used in access control situations requiring longer-range identification, such as vehicle access control and large commercial buildings.

When To Use RFID Door Lock System

Commercial Buildings

In commercial buildings, RFID access control systems enhance security by managing access points and monitoring entry and exit. They streamline access for employees and visitors while maintaining a secure environment.

RFID systems are adaptable to various commercial settings, offering scalable solutions that can integrate with other security systems, making them indispensable for modern businesses.
