How to track supply chain shipping containers with RFID technology?

In today's fast-paced global logistics industry, the efficient tracking of shipping containers is more important than ever. One of the primary challenges is the lack of real-time visibility and accurate data, which can lead to inaccuracies, stock outs, and delivery delays. Various technology based solutions can be used to digitalized the tracking and tracing of each container leaving from the warehouse, at ports, at ships, and finally arriving at the destination and technologies like UWB, RTLS and GPS, RFID, etc. play a great role in facilitating the same.

With RFID (Radio Frequency Identification) technology, businesses can now track their containers in real-time, improving supply chain visibility and streamlining operations.

How RFID Tracking Works for Shipping Containers

RFID tracking is done with the help of RFID container tags, which consist of a microchip and an antenna. These RFID tags affixed to the shipping containers emit radio frequency signals that can be detected by RFID readers. For processing and analysis, the readers capture the unique identifier from the tags.

The RFID container tags are of two types: active and passive. An active RFID tag has a power source and can transmit signals over longer distances, making it suitable for long-haul shipping. A passive RFID tag, on the other hand, depends on the energy of an RFID reader, which activates the passive tag to transmit signals. A passive tag is more cost-effective for short-range tracking and offers a cost-effective tagging of large scale shipping containers.

To track containers, RFID Fixed readers and antennas are installed at various points in the supply chain, such as ports, warehouses, and distribution centers. As containers pass through these checkpoints, RFID tags are scanned, sometimes using handheld RFID readers and SLEDs, and the data is updated in real-time, allowing companies to keep track of their containers' location and condition.

Implementing RFID Tracking in Your Supply Chain

Implementing RFID tracking in your supply chain requires some key steps to follow:

1. Assess your needs:

Find out what your supply chain needs and what challenges it faces. First, determine the areas where RFID tracking can bring the most value and the required areas to prioritize implementation accordingly.
2. Select the right RFID tags

Selecting the right RFID tag for your business is a must. So, choose wisely what is suitable for your containers and the environment they will be exposed to. Consider all the factors, like durability, read range, and compatibility with existing systems.
3. Install RFID readers and infrastructure

Determine the optimal locations for RFID readers along the supply chain, taking into account factors such as container flow, access points, and potential interference. Ensure that the necessary infrastructure, such as power supply and network connectivity, is in place.

4. Integrate with existing systems

RFID tracking should be seamlessly integrated with your existing supply chain management systems, which allow a unified view of data and facilitate data analysis and decision-making.

 5. Training and testing

Organizing some training sessions for those employees who will be using the RFID tracking system. So that they can understand how to operate the readers, interpret the data, and take appropriate actions based on the information received. Then, conduct thorough testing of the RFID tracking system before full deployment. Identify any issues or areas for improvement and make necessary adjustments to optimize performance.

RFID vs. Other Tracking Methods for Shipping Containers

While there are several tracking methods available for shipping containers, RFID technology offers unique advantages over traditional methods such as barcodes or GPS tracking.

1. Barcodes require line-of-sight scanning, which can be time-consuming and prone to errors. In contrast, RFID tags can be scanned without direct contact or line-of-sight, allowing for faster and more accurate data capture.

2. GPS tracking is another popular method for container tracking, but it has limitations in terms of coverage and accuracy. GPS signals can be blocked or weakened in certain areas, such as inside buildings or dense urban areas. RFID, on the other hand, relies on radio signals that can penetrate obstacles, providing uninterrupted tracking even in challenging environments.

Best Practices for Successful RFID Container Tracking

 To ensure successful RFID container tracking, consider the following best practices:

1. Standardize data capture

Establish clear guidelines and protocols for data capture, including tag placement, scanning procedures, and data entry formats. Consistency in data capture ensures accurate and reliable tracking information.
2. Perform regular maintenance

Regularly inspect and maintain RFID readers, antennas, and tags to ensure optimal performance. Replace damaged or malfunctioning components promptly to avoid disruptions in tracking.
3. Secure the RFID system

Implement security measures to protect the RFID system from unauthorized access or tampering. Securing the physical infrastructure, as well as implementing encryption and authentication protocols for data transmission.
4. Monitor and analyze data

Review and analyze tracking data regularly to identify patterns, trends, and improvement opportunities. So that businesses can address any issues and optimize supply chain performance.
5. Collaborate with partners

Coordinate RFID tracking processes with partners and stakeholders throughout the supply chain. Collaboration facilitates end-to-end visibility and enhances overall supply chain efficiency.

In conclusion, RFID technology has revolutionized container tracking in the logistics industry. Through real-time visibility, accurate data, and enhanced operational efficiency, RFID enables businesses to optimize their supply chain, reduce costs, and improve customer satisfaction.

As businesses embrace RFID technology, they must follow best practices and stay updated to maximize benefits like real-time visibility, streamlined receiving time, automatic tracking, and improved inventory management.
