RFID Supply Chains: Enhancing Efficiency and Transparency
RFID (Radio Frequency Identification) is a technology that uses radio waves to read and capture information that is stored on a tag or label. This tag or label is attached to an object and contains a variety of information.
In the 1970s, RFID technology was used commercially to monitor railway carriages. Then, in the 1990s, they were adopted into low-cost solutions for more efficient supply chain processes. Over time, RFID technology has evolved and led to the adaption of new technologies, making them invaluable to the industry.
In supply chain management (SCM), RFID technology is important because it enables real-time tracking and tracing of goods from manufacturing to retail. RFID tags can be read wirelessly, allowing for automatic data analysis and capture. It also reduces errors, enhances inventory accuracy, and increases efficiency.
In this article, we’ll walk you through how RFID technology benefits SCM, its applications, and the best practices for using it. We’ll also do a deep dive into some case studies on how the biggest companies in the world use it to improve their supply chain processes.
RFID Technology in Supply Chain Management
A Radio Frequency Identification (RFID) system works by using radio waves to transmit data between a reader and an RFID tag that is attached to an object. In supply chain management, RFID technology can be used to track products as they move through the supply chain.
When a product with an RFID tag moves through the supply chain, the reader detects the tag’s radio signal and reads the information stored on the microchip. This information is then transmitted to the software it works with. In turn, it enables location tracking, inventory management, and overall supply chain management.
Advantages of using RFID technology in supply chain management
RFID technology can provide several benefits in supply chain management, which include:
- Increased visibility
- Reduced labor costs
- Improve inventory accuracy
- Faster processing times
By tracking products in real time, companies can identify bottlenecks and inefficiencies in their supply chain. They can then take corrective action to improve their performance.
Comparison of RFID technology with traditional supply chain management methods
RFID technology provides a more streamlined approach to SCM compared to traditional methods. Here are just some of the key differences between these methods to illustrate how RFID has streamlined SCM processes:
Real-time data:
RFID technology allows for real-time tracking of products as they move through the chain. Traditional methods are generally unable to do this, leaving more room for error
Accuracy:
Traditional supply chain management methods rely on manual data collection and entry, which can be prone to human errors. RFID technology eliminates the need for manual entry and provides more accurate and reliable information
Cost-effectiveness:
Although RFID technology requires an initial investment, it can be more cost-effective than other methods. RFID tags can be re-used, reducing the need for manual labor, and providing significant cost savings over time.
Efficiency:
RFID technology can increase efficiency by reducing the time and labor required for inventory management and tracking. This can free up resources to focus on other aspects of the supply chain.
Better security:
RFID technology tracks products from the manufacturing process until the time it hits retail stores. With this level of tracking, it can help to prevent theft, counterfeiting, and other security risks.
Implementation of RFID technology in supply chain management
The implementation of RFID technology in SCM requires careful planning and execution to ensure that it delivers the expected benefits. By following these steps, companies can integrate RFID into their supply chains and gain a competitive advantage in the marketplace:
- Before implementing Radio Frequency Identification into a supply chain, businesses need to identify their goals and determine how the tech can be used to meet these goals. For example, companies may want to improve their inventory management or reduce lead times.
- The next step is to assess the current state of the supply chain, including the existing tech infrastructure, processes, and personnel. This can help to identify potential roadblocks in implementing RFID technology.
- Based on the goals of the business and the assessment, a roadmap should be developed. This roadmap should outline the steps required to implement RFID technology, including timelines and software requirements.
- A pilot test of the RFID technology should be conducted to ensure that it is working as expected. This can also help to identify potential issues that may need to be addressed.
- Once the pilot test is successful, the tech can be fully implemented throughout the supply chain. This may involve retrofitting existing infrastructure, training employees, and integrating it with other systems and processes.
- Continuous improvement should always be a priority. Regular monitoring and evaluation of the RFID technology’s performance can help to identify areas of improvement. It can also ensure that the supply chain is continuously optimized.
RFID Tags and Readers
How RFID tags work
Radio Frequency Identification (RFID) tags consist of a microchip and antenna that work together to transmit and receive radio waves. The microchip contains a unique identification number or other data that is stored electronically. This chip can be read by an RFID reader.
When an RFID tag comes within range of an RFID reader, the reader sends out a signal to the antenna on the tag. The energy from the signal powers the microchip, which sends a signal back to the receiver. This response typically includes information like its ID number or location.
Types of RFID tags
- Passive RFID tags: These RFID tags don’t have an internal power source. They rely on the energy from the reader to power the microchip and transmit data.
- Active RFID tags: These RFID tags have an internal power source (typically a battery). This enables them to transmit RFID data over a longer distance than passive RFID tags.
- Semi-passive RFID tags: Semi-passive RFID tags have an internal battery that powers the microchip. However, they still rely on the reader’s energy to send RFID data.
- UHF RFID tags: UHF RFID tags operate on ultra-high radio waves. They are commonly used for inventory management and tracking in supply chain applications.
- HF RFID tags: HF RFID tags work on high-frequency radio waves. They are used for access control and asset-tracking applications.
- NFC tags: These RFID tags use near-field communication technology to send data over short distances. They are typically used for mobile payments and access control.
How RFID readers work
Radio Frequency Identification (RFID) readers or RFID scanners are electronic devices that read data stored on RFID tags. They consist of an antenna, a transceiver to send and receive signals, and a processor.
When an RFID reader comes into contact or range of an RFID tag, the reader sends out a signal that is picked up by the tag. When the tag sends data back, the reader processes it and sends it to a computer or another device for analysis.
Types of RFID readers
- Handheld RFID reader: These readers are portable. They can be used to read RFID tags in a warehouse setting or in the field.
- Fixed RFID reader: These readers are installed in a fixed location. They are used for the automatic identification of RFID tags as products move through the supply chain.
- Mobile RFID reader: Mounted in a vehicle or other mobile platform, these readers are similar to fixed ones. However, they are mobile and scan RFID tags as they move through the supply chain.
- Integrated RFID reader: These readers are integrated into other devices like smartphones or tablets. They use apps and other software to scan RFID tags.
- Desktop RFID reader: Designed for desktop use, these readers are used for applications like asset tracking and access control.
- Long-range RFID reader: Used for vehicle tracking, these readers are designed to read tags from longer distances.
Integration of RFID tags and readers in supply chain management
The integration of RFID tags into supply chain management involves incorporating the technology into existing systems and processes. RFID tags are typically attached to products, pallets, or containers. This allows them to be tracked in real time through the supply chain.
RFID readers, which are located at various points along the supply chain, then read the data on the RFID tags. This helps to provide valuable information like location, status, and history. The integrations of these RFID tags and readers work similarly to the implementation of RFID technology as a whole.

Case Studies
Walmart
Walmart is one of the pioneers in the use of RFID technologies in supply chain management. In fact, in 2003, Walmart made headlines when it required its top 100 suppliers to attach RFID tags to all cases and pallets of incoming shipments.
The aim was to have RFID systems implemented company-wide by the end of 2006 to enhance Walmart’s supply chain visibility and provide more accurate ordering decisions. Of course, the implementation was not without challenges.
One of the biggest obstacles for Walmart was answering the question of who was responsible for purchasing the necessary tags. Over time, this issue was resolved by incorporating the price of the tags into the price of the products themselves.
Despite criticisms and the technology’s shaky start, Walmart persisted in its use of RFID technology. By 2010, Walmart was tracking shipments to stores as well as goods within stores company-wide. Now, all of Walmart’s U.S. locations use RFID to track incoming shipments and merchandise on the sales floor.
Coca-Cola
More than ten years ago, Coca-Cola released its RFID-enabled Freestyle fountain drink dispenser for beta testing. This put Coca-Cola on the map for innovation with RFID tech and became a quick success among customers and retailers alike.
The Freestyle dispenser had plenty to be excited about, with a standard-size dispenser that could dispense over 100 different drinks. This revolutionary machine wasn’t without its challenges, though, and needed more maintenance than a traditional soda machine. This is where RFID tech came in for the industry giant.
Every individual flavor cartridge came from the plant marked with a passive RFID tag. This was then read by the machine to ensure proper installation and track the contents of the cartridge. The machine also used RFID to record the number of times a particular drink had been selected and relayed the data back to Coca-Cola.
Not only was this revolutionary for understanding customer demand, but it also allowed Coca-Cola to gain more control over stock replenishment and overall inventory control. This allowed for more efficient supply chain management within the company’s factories.
Zara
With over 2,200 stores worldwide and more than 20 clothing lines launched every year, Zara’s main need for RFID adoption was for tighter inventory regulation. Now, RFID technology helps Zara to achieve clear visibility and availability of products on the shelves. This allows both retailers and customers to check whether specific garments are available.
RFID tags are embedded in each garment, which allows for separate identification of each product through radio signals. The mechanism enables efficient distribution of products, accurate in-store product management, speedy stock replenishment, and reliable inventory counts.
To use this technology in its supply chain management, Zara’s logistics team identifies which shipments need to be replenished through the RFID system. In turn, this helps to keep inventory levels accurate and up-to-date.
Not only does RFID help to prevent over or under-stocking, but it also prevents theft and loss. Zara has installed RFID scanners at security counters in all of its stores, which can help to control shoplifting and theft. This is a cost-effective solution to lowering loss because the tags can be reused and recycled.
By 2019, Zara has already implemented this technology in over 700 stores. Overall, RFID technology has played a significant role in Zara’s success, allowing for more precise and agile product management.
Airbus
Several years ago, Airbus announced that it was deploying RFID part-marking to all its aircraft families, making it the first commercial aircraft manufacturer to do so.
This technology would be employed for all seats and life vests for various aircraft lines, with the objective of enhancing supply chain transparency. Moreover, Airbus could reduce human errors and increase its savings by automating certain processes.
The application of RFID part marking enabled this automation, particularly in manufacturing. The RFID tags affixed to the components verified the presence of each part, confirmed its location, and checked its maintenance history for quality assurance. This data allowed Airbus to establish the aircraft configuration and prioritize maintenance planning.
Additionally, with RFID part-marking, every Airbus aircraft would arrive pre-equipped with RFID tags on its parts, offering a larger scope for efficiency savings with permanent RFID marking.
In the past, hundreds of seats and life jackets in the cabin had to be inspected and recorded manually. However, with the introduction of RFID technology, a single person could read the tags within a few minutes by using a handheld reader.
