Enhancing Yard Management with RFID Tags

In the fast-paced world of logistics and supply chain management, efficiency and accuracy are paramount. Radio Frequency Identification (RFID) technology offers a significant leap forward in managing yard operations. This article explores the integration of RFID within yard management systems (YMS), discussing its functionality, benefits, and potential drawbacks. By understanding what RFID is and how it can revolutionize a yard management system, yard managers can better prepare for a more streamlined, secure, and efficient future.

What is RFID?

RFID, or Radio Frequency Identification, is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. In transportation management systems (TMS), warehouse management systems (WMS), and yard management systems (YMS), RFID tags are used to track assets such as trailers, containers, and even personnel.

Unlike barcodes, RFID tags do not require a line of sight for scanning. This allows for more flexibility and speed in tracking multiple items simultaneously. This technology lends itself to improved operational visibility, as assets are constantly being tracked without human oversight.

RFID Tag and Reader Technology: How Does it Work?

RFID is comprised of two key components: tags and readers. A tag, which may be attached to an asset, contains a chip and antenna that transmits data to the reader. The reader then receives the radio wave data and converts it into tangible, digital data. This technology allows for real-time visibility into assets and containers, a crucial element of yard management.

Gain real-time visibility into inbound and outbound shipments, resource utilization, yard activities, gate congestion, and so much more with a yard management system bolstered by RFID technology.

Types of RFID Tags

There are two primary types of RFID tags: active and passive. Each type has its own applications, with passive tags typically used for inventory tracking due to their lower costs. The type of tag you choose will depend on the specific requirements of your yard, transportation, or warehouse management system.

Active RFID tags have their own power source and can typically transmit signals over longer distances. They are usually equipped with a battery, enabling them to transmit signals at higher power levels. An example of an active RFID tag would be in logistics hubs, where tracking the exact location of containers or trailers in real time is essential for operations.

Passive RFID tags do not have their own power source. Instead, they are powered by the electromagnetic energy transmitted from the RFID reader. Due to this dependent relationship, passive tags have shorter read ranges — but are typically much more cost-effective. An example of a passive RFID tag is in retail environments for inventory management. A clothing store may attach a passive tag on each garment, helping workers quickly scan multiple items at the point of sale.

RFID Tags v RFID Labels, What’s the Difference?

We’ve already explained tags in relation to RFID, but what are labels? While both use radio frequency technology to track and identify objects, they differ in design, usage, and applications. Where tags are built to withstand harsh environments and have a long shelf life, labels are essentially adhesive stickers designed to be more temporary and flexible.

RFID labels are meant to be applied directly to items, similar to how a barcode label would be attached to an item. This grants the yard manager a more cost-effective inventory-tracking solution, especially in environments where conditions are controlled and less harsh. In these settings, there’s no concern about the label being ripped off or withered. Due to their ease of use and low cost, RFID labels are ideal for single-use or items that do not require the ruggedness of tags.

RFID Technology & Yard Management Systems

The integration of RFID into yard management solutions marks a significant shift in how logistics operations manage and track assets. This game-changing solution offers a sophisticated method for increasing the visibility and control of every yard asset while simultaneously limiting the number of manual processes required. Keep reading to learn how this technology streamlines inventory management and improves overall efficiency in the yard.

Benefits of Using RFID Tags in Yard Management

Asset Tracking & Visibility

Receive real-time data on the whereabouts of every tagged asset in your yard. No more worrying about misplaced assets — everything with an RFID tag can be located swiftly. This also allows you to prepare for when you’re reaching your yard capacity.

Efficiency and Improved Throughput

The ability to easily track assets anywhere in the yard improves efficiency and throughput. When yard assets are tagged with RFID, yard managers can optimize workflows, reduce gate congestion, and limit loading/unloading times. Improve your dock scheduling capabilities with the assistance of RFID.

Security Access and Control

Another benefit of RFID is its application to improve security measures. These systems can be used to control access to restricted areas and ensure that only authorized personnel can access certain assets or locations. Gate management is no longer entirely dependent on human workers.

Drawbacks of Using RFID Tags in Yard Management

Increased costs

One of the primary challenges associated with RFID technology is the initial investment. Implementing this technology requires purchasing tags, installing readers, and integrating them with the existing yard management system in place. While this upfront investment will not be cheap, the long-term benefits will likely justify the expense. Remember to make informed decisions and not commit to any changes you can’t afford.

Technical Complexities

Installing RFID systems into existing yard management software can be a logistical challenge. Some technical expertise will be required to ensure that the new RFID components clearly communicate with the existing YMS. During this phase, teams may notice implementation delays and roadblocks that disrupt ongoing operations.

Environmental Interference

RFID systems can be susceptible to interference from metals and liquids, which can interrupt the radio waves used to communicate with RFID tags. This can pose a significant threat in yards with high metal content or containers storing liquid materials. Facility managers must monitor all yard activity and note where these susceptible materials are located so they can carefully plan out the placement of RFID readers.

Implementation Considerations for RFID in Yard Operations

Before upgrading your yard management software with RFID capabilities, it’s important to step back and assess what your yard currently has. Then, identify what your yard needs.

Is the goal to gain actionable data, increase throughput, enhance security, or all of the above? Understanding these goals helps you choose the right type of RFID system that fits the operational demands. Every yard has unique operational characteristics and challenges. Start by identifying those.

Once your needs are established and you’ve determined you want to move forward with RFID implementation, you must decide which type of RFID tags are right for your business. Earlier, we discussed the difference between active and passive tags. One is designed for long-distance asset tracking, while the other is meant for shorter distances.

You must also consider your current technological infrastructure and determine whether it’s properly equipped to handle RFID implementation. Do you already use yard management software in your daily operations? Do you already have scanners, readers, and other software systems installed? If so, can the new RFID system seamlessly integrate with these components?

Finally, determine if the ROI will be worth it in the end. Consider the cost savings that will result from this new technology. Does that outweigh the cost of the initial installation investment? Cost savings may come in the form of reduced labor costs, increased efficiency, and improved asset utilization.
