How to Use RFID in Shipping Container Tracking

Introduction

RFID is a powerful technology that can significantly enhance the tracking and management of shipping containers. By attaching RFID tags to containers and using RFID readers at strategic points, companies can achieve real-time visibility, improved security, and operational efficiency in their supply chains. This article will cover the benefits, technology, implementation steps, challenges, and best practices of using RFID for shipping container tracking.

Understanding RFID Technology

RFID Components:

RFID Tags: RFID tags on shipping containers are used to enhance tracking and management of cargo during shipping.

RFID Readers: RFID readers emit radio waves to communicate with tags. They can be fixed RFID readers, Mobile RFID readers, and Handheld RFID Readers.

RFID Antenna: RFID Antennas are used by readers to send and receive signals from tags that are attached to the container.

RFID Middleware: Software that processes the data collected by readers and integrates it with other systems.

Types of RFID Tags:

There are two types of RFID Tags-

Passive Tags: These RFID tags have no internal power source and are activated by the reader's electromagnetic field. They are cheaper and have a longer lifespan.

On containers, we use e-seal RFID Tags to track the containers.

TagMatiks Gorilla Tags -TagMatiks Gorilla Mini TAG-GO-E-MINI is a robust outdoor-rated rugged RFID tag equipped with IMPINJ MONZA R6P chip technology having 96-bit or 128-bit EPC memory plus 64-bit or 32-bit user memory, delivering exceptional read range and accuracy. typically designed for on-metal asset tracking.

Active Tags: These tags have an internal battery, allowing them to transmit signals over longer distances for a Container. They are more expensive and have a shorter lifespan.

Using RFID technology for tracking shipping containers can greatly enhance the efficiency, accuracy, and security of the logistics process of shipping Containers.

Here’s a step-by-step guide on how to implement RFID in shipping container tracking:

1. Choose the Right RFID System for Shipping Container

RFID Tags: Select appropriate RFID tags (active or passive) based on the range and environment. Active tags have a longer range and battery life, while passive tags are cheaper and have a shorter range. It depends on how long it will travel.

RFID Readers: Choose fixed RFID readers or handheld RFID readers. Fixed readers are installed at checkpoints, like gates, while handheld readers are used for spot checks.

Middleware: TagMatiks implements software that integrates with your existing logistics management system to process RFID data.

2. Tag the Containers

Attach RFID tags to the containers. The tags should be placed where they can be easily read by RFID readers and protected from potential damage.

Use tamper-evident tags for security purposes to prevent unauthorized removal or tampering.

3. Install RFID Readers

Entry and Exit Points: Install fixed RFID readers at key points such as loading docks, gates, and checkpoints to automatically read tags as containers pass by.

Mobile Readers: Equip vehicles or personnel with handheld readers for spot-checks and inventory audits.

4. Set Up the RFID Software

Integrate RFID middleware with your existing transportation management system (TMS) or warehouse management system (WMS) to handle the data captured by RFID readers.

Configure the software to update container status, location, and other relevant data in real time.

RFID Software which is used for tracking containers is TagMatiks AT.

Tagmatiks AT has many features for tracking containers-

• TagMatiks AT is designed to be easily adaptable for different asset tracking needs
• The platform automates asset audits and cycle counts, using RFID handheld devices to quickly capture assets at each location and immediately identify any variances.
• TagMatiks AT is a cloud-based solution, it can be accessed via most web browsers.
• TagMatiks AT provides comprehensive support for RFID and other sensory technologies, tracking assets with both fixed and handheld RFID readers.
• The system supports a variety of RFID tagging methods, including pre-printed tags, custom printing options, and an association module for tagging assets.
• RFID Software offers numerous out-of-the-box reports to aid in business decision-making. Users can also design custom reports for more specific insights, leveraging real data for better outcomes.

5. Implement Tracking and Monitoring of shipping container

Use the integrated system to monitor the real-time location and status of containers.

Set up alerts and notifications for container arrival, departure, delays, or tampering events.

6. Data Management and Analysis

Collect and analyze the data for insights on logistics performance, container utilization, and supply chain efficiency.

Use the data to optimize routes, improve inventory management, and reduce costs.

Benefits of RFID in Shipping Container Tracking

Real-time Visibility:

• Enables real-time tracking of containers from the point of origin to the final destination.
• Provides accurate information on the location and status of containers.

Improved Efficiency:

• Reduces manual data entry and paperwork.
• Speeds up the process of container identification and inspection at ports and checkpoints.

Enhanced Security:

• Helps prevent theft and unauthorized access to containers.
• Provides alerts for tampering or breaches.

Cost Savings:

• Reduces losses from misplaced or stolen containers.
• Minimizes delays and operational bottlenecks.

Applications of RFID Container Tracking-

RFID container tracking is a powerful tool that enhances the efficiency and accuracy of managing containers in various industries.

Shipping and Logistics: Tracking cargo containers in ports and during transportation.

Manufacturing: Monitoring the movement of raw materials and finished goods in Containers.

Retail: Managing inventory and tracking shipments from warehouses to stores.

Healthcare: Tracking medical equipment and supplies from Factory to Container.

Conclusion

Implementing RFID for shipping container tracking can revolutionize supply chain management by providing real-time visibility, enhancing security, and improving operational efficiency. By carefully planning and executing the implementation, and by addressing potential challenges with effective solutions, companies can harness the full potential of RFID technology to streamline their logistics operations.
