Operation, Maintenance and Service of LF RFID Tags 

Low Frequency (LF) RFID tags are commonly used in asset management, livestock tracking, and industrial automation. These passive tags do not contain a battery and rely on the electromagnetic field generated by an RFID reader for operation. When an LF RFID reader emits a low-frequency signal (typically 125 kHz or 134.2 kHz), the tag’s antenna picks up this energy, powering the microchip to send data back to the reader. Due to their reliance on inductive coupling, LF RFID tags work well in environments with metal or water, which often disrupt higher frequency tags. 

For optimal performance, LF RFID tags should be strategically placed on assets to maximize readability and minimize interference. Because these tags have shorter read ranges compared to their high-frequency counterparts, placement is crucial, especially in applications like industrial automation or animal identification. Once activated by a reader, the tag transmits data—such as a unique identification number or encoded information—back to the system for processing and logging. 

Maintenance of LF RFID tags is generally low effort, given their passive nature and lack of internal power sources. However, routine inspections are recommended, particularly in harsh environments where tags may be exposed to chemicals, extreme temperatures, or mechanical impact. Ensuring that the encapsulation of the tag is intact will help maintain its longevity and functionality. Tags embedded in animals or outdoor equipment may need cleaning or replacement after extended use or exposure to the elements. 

In the event that a tag becomes unresponsive, troubleshooting typically involves inspecting the antenna for damage or interference, ensuring the RFID reader is functioning properly, and checking that the tag is within the recommended reading range. GAO RFID provides diagnostic tools and expert technical support to address these issues, either remotely or onsite, ensuring minimal disruption to operations. 

Workplace Standards and Regulations in the U.S. and Canada 

The use of LF RFID tags in the U.S. and Canada is subject to specific regulations. In the United States, the Federal Communications Commission (FCC) mandates that LF RFID systems comply with Part 15 of its rules, which govern radio frequency devices and limit emissions that may cause interference with other communications systems. Compliance with FCC standards ensures that RFID tags do not interfere with other electronic systems in the workplace, making them safe for deployment in industrial, commercial, and agricultural environments. 

In Canada, Industry Canada (IC) imposes similar regulations for RFID devices, ensuring that electromagnetic emissions are within safe limits. LF RFID tags used for livestock management, for example, must meet the standards set by Agriculture and Agri-Food Canada, which enforces RFID tagging for animal identification to ensure traceability and food safety. Tags used in commercial applications must also adhere to the Canadian Standards Association (CSA) guidelines for electrical equipment, ensuring that they are safe for use in the workplace. 

GAO RFID ensures that all LF RFID tags we provide comply with these U.S. and Canadian regulatory requirements, including FCC, IC, and CSA standards. Our commitment to quality assurance means that each tag is rigorously tested for electromagnetic compatibility, durability, and reliability in various operational environments. 

Case Studies 

• Asset Management – Houston, USA: An oil and gas company in Houston implemented LF RFID tags to track high-value tools and equipment across multiple job sites. The system improved asset visibility and reduced losses due to misplaced items, ultimately improving operational efficiency.

• Livestock Tracking – Des Moines, USA: In Des Moines, an agricultural business used LF RFID tags to monitor cattle across several farms. The implementation allowed for seamless tracking of individual animals, aiding in health monitoring and compliance with federal traceability regulations.

• Waste Management – Toronto, Canada: A waste management firm in Toronto deployed LF RFID tags to track waste bins and optimize collection routes. The system helped reduce operational costs and improved service delivery by providing real-time data on bin usage and location.
