Active RFID Use Cases

Radio Frequency Identification (RFID) technology has revolutionized various industries, and manufacturing is no exception. While passive RFID has been widely adopted for tracking and inventory management, active RFID takes the capabilities to a whole new level. Active RFID tags are equipped with their own power source, allowing them to actively broadcast information, enabling real-time tracking and monitoring of assets. In this article, we will explore five key use cases where manufacturers can harness the power of active RFID technology to enhance their operations.


Common Uses for RFID

RFID technology has gained widespread adoption across various industries due to its versatility and efficiency. Here are some common uses for RFID: 

  • Asset Tracking and Management 
  • Inventory Management 
  • Work-in-Process (WIP) Tracking 
  • Quality Control and Product Authentication 
  • Worker Safety and Security 

Some applications may require active RFID technology. So, it may be helpful to know the difference between passive and active RFID. 


What is Active RFID?

Active RFID (Radio Frequency Identification) is a technology that enables the wireless identification and tracking of objects or assets using radio frequency signals. Unlike passive RFID, which relies on the power provided by the RFID reader to activate and communicate with tags, active RFID tags have their own power source, typically a battery. This power source allows active RFID tags to actively broadcast signals, making them capable of longer read ranges and continuous communication with RFID readers. 

Active RFID tags typically consist of a microchip, an antenna, and a battery. The battery provides power to the tag, allowing it to transmit signals at regular intervals or in response to specific events. These tags can be attached to objects or assets such as vehicles, containers, equipment, or even people, providing real-time tracking, monitoring, and data transmission capabilities. 

Active RFID systems consist of RFID readers, antennas, and a software platform for data processing and management. The RFID reader emits radio frequency signals, which are received by the active RFID tags. The tags then respond by transmitting their unique identification information, along with other data if applicable, back to the RFID reader. This bidirectional communication enables real-time tracking and monitoring of tagged objects or assets. 

Active RFID technology offers several advantages over passive RFID: 

  • Longer Read Ranges: Active RFID tags have a greater read range compared to passive tags, allowing for tracking over larger distances. This makes them well-suited for applications such as vehicle tracking or monitoring assets within a wide area. 
  • Continuous Communication: Active RFID tags actively broadcast signals at regular intervals, providing real-time updates on location, status, or other relevant data. This continuous communication enables real-time tracking and monitoring of assets. 
  • Enhanced Data Transmission: Active RFID tags have the ability to transmit more data compared to passive tags. This allows for additional information such as temperature readings, sensor data, or battery status to be included in the transmitted signals. 
  • Autonomous Operation: Active tags have their own power source, making them independent of external power. This allows them to operate autonomously, providing continuous tracking and monitoring capabilities without relying on an external power supply. 
  • Versatility and Customization: Active RFID technology can be customized to suit specific application requirements. Tags can be designed with various form factors, battery life options, and additional sensors to meet the specific needs of different industries or use cases. 


Active RFID Use Cases

Active RFID technology offers a wide range of specific use cases across various industries. Here are a few specific ways in which active RFID technology can be utilized: 

  1. Environmental Monitoring: Active RFID tags can be used to monitor environmental conditions, such as temperature, humidity, and vibration. This can be used to improve the safety of assets and to prevent damage to equipment. For example, a company that stores hazardous materials could use active RFID tags to monitor the temperature of the storage facility in order to ensure that the materials do not reach a dangerous level. 
  2. Cold Chain Monitoring: Active tags with temperature sensors can be used to monitor and maintain the quality and integrity of temperature-sensitive goods during transportation and storage. For example, in the pharmaceutical or food industries, active RFID tags can continuously monitor temperature conditions, providing real-time alerts if there are any deviations from the specified range. This helps ensure compliance with regulatory requirements and guarantees the quality and safety of perishable products. 
  3. Tool and Equipment Management: Active tags can be attached to tools and equipment, allowing manufacturers to track their location and usage. This ensures that the right tools are available when and where they are needed, reducing downtime and improving productivity. Manufacturers can also monitor tool maintenance schedules and receive alerts for preventive maintenance, ensuring optimal performance and prolonging the lifespan of expensive equipment. 
  4. Personnel Tracking and Safety: Active tags integrated into employee badges or PPE can enhance worker safety by monitoring their location within the manufacturing facility. In hazardous environments, such as construction sites or chemical plants, active RFID technology can be used to ensure workers are in designated safe zones and to trigger alarms or alerts in case of emergencies. This application improves worker safety, enables quick response in critical situations, and helps manage evacuation procedures effectively. 
  5. Returnable Asset Tracking: In manufacturing operations that involve the use of returnable assets, such as containers, pallets, or racks, active RFID tags can be attached to these items to enable efficient tracking and management. By monitoring the movement of returnable assets in real time, manufacturers can optimize their utilization, reduce loss or theft, and ensure timely return and replenishment. This streamlines supply chain operations, minimizes the need for manual inventory checks, and improves asset visibility. 

These specific applications highlight the versatility and value of active RFID technology in various industries. By leveraging real-time tracking, monitoring, and data collection capabilities, manufacturers can streamline operations, improve efficiency, reduce costs, enhance safety, and achieve better visibility and control over their assets and processes. Active RFID technology is a powerful tool that enables manufacturers to optimize their operations and stay competitive in today’s fast-paced business landscape.



In conclusion, active RFID technology offers organizations a wide range of applications to optimize their operations and enhance overall efficiency. By leveraging active RFID for asset tracking and management, inventory control, work-in-process tracking, quality control, and worker safety, manufacturers can gain real-time visibility, streamline processes, and make data-driven decisions. With the ability to track and monitor assets, products, and personnel in real time, manufacturers can achieve greater operational excellence, reduce costs, and improve customer satisfaction. Embracing active RFID technology is a strategic move for manufacturers looking to stay competitive in today’s rapidly evolving manufacturing landscape.
