Track and trace

What Is Track and Trace?

Track and trace refers to the process of identifying the current and past locations of an item, product, or shipment throughout its journey in a supply chain. This capability falls under the broader category of supply chain finance and logistics, providing granular visibility into the movement of goods from their origin to their final destination. The primary objective of track and trace systems is to enhance transparency, improve operational efficiency, and mitigate risks associated with product authenticity, quality, and delivery. By capturing key data points at various stages, track and trace enables stakeholders to monitor an item's progress, verify its status, and quickly respond to disruptions or anomalies.

History and Origin

The concept of track and trace has evolved significantly from early manual record-keeping to sophisticated digital systems. A pivotal development in the history of tracking goods was the invention and widespread adoption of the barcode. The barcode, a system inspired by Morse code, was first patented in 1952 by Norman Joseph Woodland and Bernard Silver, though it took decades for the necessary technology, such as laser scanners and commercial computing, to become widely available. The commercial breakthrough occurred on June 26, 1974, when a pack of Wrigley's Juicy Fruit gum, marked with a Universal Product Code (UPC) barcode, was scanned at a supermarket in Troy, Ohio. This event marked a silent revolution in logistics by enabling automated product identification and revolutionizing how products are purchased, stored, and distributed globally.⁵ Since then, the evolution of track and trace has incorporated more advanced technologies like Radio Frequency Identification (RFID), Global Positioning Systems (GPS), and the Internet of Things (IoT), moving beyond simple product identification to comprehensive real-time monitoring and data collection.

Interpreting the Track and Trace

Interpreting track and trace data involves analyzing the information collected at various points in a product's journey to understand its movement, status, and integrity. For businesses, this means being able to pinpoint where a product is at any given moment, its historical path, and any events or changes it underwent (e.g., temperature excursions for perishable goods). This data is crucial for effective asset tracking and ensuring that goods are progressing as planned. For instance, if a shipment is delayed, track and trace data can identify the exact point of delay, allowing for proactive communication with customers or the implementation of alternative arrangements. Furthermore, the ability to trace a product back to its origin and forward to its destination aids in conducting due diligence and verifying ethical sourcing practices, which is increasingly important in global trade.

Hypothetical Example

Consider a pharmaceutical company distributing a vaccine. Each vial of vaccine is assigned a unique serial number, which is linked to its manufacturing batch, date, and specific production facility. As the vials move from the factory to a distribution center, then to a regional warehouse, and finally to hospitals or clinics, a track and trace system records each movement.

Manufacturing: The serial number is scanned and linked to the production details and quality control data.
Packaging: Vials are aggregated into cartons, and cartons into pallets. Each carton and pallet receives its own unique identifier, digitally linking it to the individual vials contained within.
Shipment: When a pallet leaves the factory, its identifier is scanned, noting its departure time, carrier, and destination. This updates its status in the system, initiating the tracking process.
Transit Points: At each major transit hub or change of custody (e.g., from factory truck to air cargo), the pallet is scanned again. This creates a chain of custody, verifying its path and ensuring no unauthorized diversions.
Receiving: When the pallet arrives at a regional warehouse, its identifier is scanned upon receipt, confirming its arrival and updating inventory management records.
Dispensing: At the hospital, individual vaccine vials might be scanned as they are administered, providing an end-to-end record from manufacturing to patient use.

If a quality issue arises with a specific batch, the company can use its track and trace system to quickly identify exactly where all vials from that batch are located, or where they have been distributed, enabling a targeted and efficient recall. This capability significantly enhances public safety and minimizes financial losses.

Practical Applications

Track and trace systems are integral across various sectors, extending beyond basic product movement to impact financial and operational strategies. In the realm of finance, these systems are crucial for optimizing working capital by providing accurate, real-time data on inventory in transit, allowing for better cash flow forecasting and reduced holding costs. From a regulatory standpoint, track and trace is often mandated to ensure product safety and authenticity. For example, the U.S. Food and Drug Administration (FDA) has implemented the Food Traceability Rule (FTR) to establish additional traceability recordkeeping requirements for certain foods, allowing for faster identification and removal of potentially contaminated items from the market.⁴ This helps to protect public health and maintain consumer trust.

Beyond regulatory frameworks, track and trace is widely applied in:

Anti-Counterfeiting: Unique product identifiers and their digital trails help verify authenticity, combating the proliferation of fake goods that can erode brand value and consumer safety. The World Intellectual Property Organization (WIPO) highlights the critical role of robust systems in fighting counterfeiting to protect intellectual property rights globally.³
Recalls and Returns: The ability to precisely locate affected products streamlines recall processes, minimizing health risks and financial exposure. It also simplifies reverse logistics.
Quality Assurance: Monitoring conditions during transit (e.g., temperature, humidity) for sensitive goods like pharmaceuticals or food, ensuring products maintain their integrity from procurement to delivery.
Supply Chain Optimization: Providing data for data analytics to identify bottlenecks, optimize routes, and improve delivery predictability.

Limitations and Criticisms

Despite its numerous benefits, track and trace implementation can face significant challenges. One primary limitation is the issue of inconsistent data across various supply chain partners. Different entities within a chain may use disparate systems and data formats, leading to fragmented, outdated, or duplicated information, which hinders the ability to maintain a reliable tracking record.² This lack of standardization makes seamless integration difficult and can compromise the integrity of the end-to-end traceability solution.

Other criticisms and limitations include:

Cost of Implementation: The initial investment in technology (e.g., RFID readers, sophisticated software, blockchain solutions) and the ongoing costs of maintenance and training can be substantial, particularly for smaller businesses.
Technology Integration Challenges: Integrating new track and trace systems with existing legacy Enterprise Resource Planning (ERP) and supply chain management (SCM) systems can be complex and require significant technical expertise.¹
Data Accuracy and Real-time Limitations: Manual data entry points in a process introduce opportunities for human error, affecting data accuracy. Furthermore, achieving true real-time visibility across all stages, especially in complex global supply chains, remains an ambitious goal for many organizations.
Resistance to Change: Stakeholders within the supply chain may be reluctant to adopt new processes or share sensitive data, impacting the overall effectiveness of a collaborative track and trace system.
Regulatory Complexity: Varying compliance requirements across different countries and industries can add layers of complexity to global track and trace initiatives.

Track and Trace vs. Supply Chain Management

While closely related, track and trace is a specific function that contributes to the broader discipline of supply chain management. Supply chain management (SCM) encompasses the comprehensive oversight of the entire flow of goods and services, from the sourcing of raw materials to the delivery of finished products to the consumer. SCM involves strategic planning, procurement, production, logistics, and relationship management with suppliers and customers. Its goal is to optimize the entire network for efficiency, cost-effectiveness, and customer satisfaction.

Track and trace, on the other hand, is a tactical tool within SCM that focuses specifically on visibility—knowing where products are and where they have been. It provides the granular data necessary for SCM to make informed decisions regarding inventory management, risk management, and compliance. While SCM sets the overarching strategy and coordinates all activities, track and trace provides the essential information stream that allows those strategies to be executed, monitored, and adjusted effectively.
