Barcode and RFID: Asset Identification Technologies in Reusable Packaging Systems
Guest blog from Angelique T. Hoefl, PMG Labels LP (MHI member company)
In modern reusable packaging loops, individual asset identification is essential for maintaining supply chain efficiency. Without accurate tracking of returnable transport items (RTIs), such as totes, plastic crates, and pallets; organizations face inventory shrinkage, prolonged cycle times, and operational bottlenecks.
To maintain visibility across complex transport networks, industrial logistics rely primarily on two key identification standards: optical barcodes and Radio-Frequency Identification (RFID).
Barcode: Visual, Process-Driven Identification
Barcode technology relies on line-of-sight optical scanning, meaning that data capture occurs through deliberate interaction with a physical label. While barcodes require manual or targeted scanning and cannot be captured automatically in transit without line-of-sight, they offer a highly reliable and cost-effective foundation for structured workflows.
Key characteristics include:
• Line-of-sight optical scanning of printed barcodes
• Explicit and intentional data capture at predetermined process checkpoints
• Direct integration into established warehouse and enterprise IT systems
• Universal industry-wide adoption across global logistics networks
Barcodes remain the standard for processes where assets pass through defined manual checkpoints; such as receiving stations, visual inspection areas, and quality control stops.
RFID: Automated, Touchless Data Capture
Radio-Frequency Identification (RFID) utilizes electromagnetic fields to transmit data wirelessly, eliminating the need for line-of-sight or manual intervention.
Key characteristics include:
• Contactless data transmission without visual scanning
• Bulk reading capabilities to register multiple assets simultaneously
• Automated capture through RFID dock doors, portals, and conveyor belts
• High data capacity suited for real-time tracking in fast-paced environments
RFID is particularly advantageous in dynamic, high-volume logistics environments where manual scanning would introduce delays or human error.
A Complementary Approach to Reusable Transport Items (RTIs)
Rather than mutually exclusive alternatives, barcode and RFID technologies serve complementary roles within modern asset management frameworks. Both ensure that physical assets remain uniquely identifiable across their operational lifecycle, differing primarily in how data is collected and processed:
• Barcodes manage discrete manual checkpoints, intake procedures, and general inventory audits.
• RFID drives automated tracking through high-speed transport loops, loading docks, and high-density warehouse gates.
As supply networks become increasingly interconnected, end-to-end asset identification is essential for preventing loss and optimizing container utilization.
“Barcode and RFID are proven technologies for tracking assets in industrial and logistics applications,” notes Tobias Hoefl, President of PMG Labels. “In modern reusable packaging systems, leveraging the right technology for the right process step delivers complete supply chain visibility and long-term efficiency.”
