What is RFID Asset Tracking?

In an era where information is power and efficiency is king, the landscape of asset tracking has undergone a revolution. This transformation is powered by RFID (Radio-Frequency Identification) technology—A world where every item, from a small package to a massive machine, holds its own digital identity and can be effortlessly tracked in real time. This innovation isn’t a mere concept; it’s a tangible reality propelling industries forward at an unprecedented pace. RFID technology- active, passive and NFC are all making this a reality and powering businesses to run more effectively and allowing them to save big money.

RFID’s roots trace back to the mid-20th century when it emerged as a military spy tool. However, its true potential didn’t fully blossom until recent decades. Consider this: according to a recent survey by Market Research Future, the global RFID market is projected to reach a staggering $40 billion by 2025, reflecting a compounded annual growth rate of over 15%. These numbers aren’t just arbitrary figures; they signify a paradigm shift in how organizations perceive and harness the power of tracking and managing their assets.

But what exactly is RFID asset tracking, and why has it become an indispensable asset for businesses worldwide? Let’s delve deeper into this transformative technology to unravel its significance and impact on modern-day asset management strategies.

What is RFID Asset Tracking?

RFID asset tracking works with the help of hardware such as tags. As an asset business owner of high value assets such as equipment, IT devices, tools, or vehicles, you are most likely aware of the importance of asset tracking and inventory management as a means to support decision making, prevent losses, and maximize asset utilization rates.

There are many ways to track assets. The old fashioned way is to do it manually by using pen and paper or Excel sheets. However, with the advent of technology, utilizing RFID technology is by far the most cost effective and efficient way.

How RFID Asset Tracking Works
  1. RFID technology operates on a simple yet powerful principle: using radio waves to transfer data between an RFID tag and a reader. The tag consists of a microchip that stores information about the item it’s attached to, and an antenna that enables communication via radio waves. When the tag is within the range of an RFID reader, typically a few inches to several feet away depending on the type of RFID, the reader sends out electromagnetic waves that power the tag and prompt it to transmit its data back to the reader.

    There are three primary types of RFID systems based on how the tags are powered and communicate:

    • Passive RFID: These tags don’t have an internal power source. Instead, they draw power from the RFID reader’s signal. When the reader emits radio waves, the passive tag’s antenna picks up the energy to activate the chip, allowing it to transmit its data back to the reader. Passive RFID tags are cost-effective and can be supplied in different forms such as stickers or waterproof tags making them suitable for a wide range of applications like inventory management, access control, supply chain tracking, bin tracking for waste applications and more.
    • Active RFID: In contrast, active RFID tags are typically powered by an internal battery and can transmit signals without relying on the reader’s energy. This allows Active RFID tags to broadcast signals over much longer distances and at higher frequencies compared to passive tags, making them ideal for tracking high-value assets, vehicles, or in scenarios requiring real-time location tracking and even in cold chain applications allowing temperature sensors to transmit wirelessly.
    • Semi-passive (Battery-Assisted Passive) RFID: This type combines features of both passive and active systems. Semi-passive tags have a battery to power the tag’s internal circuitry but still rely on the reader to communicate. They offer extended read ranges compared to passive tags and conserve battery life by only activating when in the presence of an RFID reader. This type is commonly used for monitoring temperature-sensitive goods during transit.

    RFID systems consist of various types of tags and readers based on frequency bands and applications. Low-frequency (LF), high-frequency (HF), ultra-high-frequency (UHF), and microwave frequency bands are used in RFID systems, each with its own advantages in terms of read range, data transfer speed, and resistance to interference.

    LF RFID is often used for access control, HF for payment systems and near-field communication (NFC), UHF for supply chain management and inventory tracking, and microwave frequencies for specialized applications like toll collection and vehicle tracking.

    Understanding these distinctions helps businesses choose the right RFID system for their specific needs, whether it’s enhancing security, improving logistics, or optimizing inventory management.

Case Study-Real-World Example of RFID For Waste Tracking

A large waste management company in Canada was facing the relentless challenge of optimizing their operations amidst increasing demand for efficiency and sustainability from their customers and the cities they work with.

With our GPS trackers seamlessly integrated into their fleet of trucks, equipped with a robust passive RFID reader, the company revolutionized their waste collection process. Every residential waste bin tagged with a passive RFID tag became a part of an intricately connected network. As the trucks drive processes along their routes, the RFID tags on each bin is picked up by the RFID reader, automatically logging each pickup in real time.

In addition to this, the trucks are equipped with our comprehensive camera system. Six cameras- dual-facing dashcam, side cameras, a rear camera, and a dedicated hopper camera—recording the journey of each truck and waste bin from curbside to collection point.

This technological prowess wasn’t just about surveillance; it was about accountability and safety. The system diligently logged driver behavior events, promoting responsible driving practices and ensuring the safety of both drivers and pedestrians.

Moreover, a simple yet impactful addition to the system transformed the driver into an instant problem solver. A button installed within the cabin became a bridge between observation and action. If a driver noticed an issue with a particular waste bin—a broken latch, an overflowing container—he pressed the button, triggering the hopper camera to snap a photo of the concern. This image, along with the timestamp and geolocation, was swiftly uploaded to Fleet.Net, notifying the operator and streamlining issue resolution.

Through this innovative solution, the waste management company witnessed a paradigm shift. Operational efficiency soared as routes were optimized, pickups were precisely logged, and proactive issue resolution became the norm. The fusion of GPS tracking, passive RFID technology, and an innovative camera system transformed mere waste collection into a symphony of efficiency and responsiveness, setting a new standard in waste management excellence.
