RFID technology is revolutionizing pharmaceutical supply chains, but its impact depends heavily on how drug data is encoded on RFID tags. This blog post explores three primary encoding methods—license plate, RAIN, and GS1—and compares their benefits and limitations. While license plate and RAIN models offer cost savings and moderate interoperability, they rely on external databases, creating long-term challenges. The GS1 standard, by contrast, embeds key drug details directly in the tag, enabling seamless, standards-based tracking across systems. For pharmaceutical companies aiming to future-proof operations and meet global regulatory requirements, GS1 offers the most scalable and interoperable solution.

RFID technology is revolutionizing pharmaceutical supply chains by enabling automated, accurate, and secure tracking of drug products. Unlike barcodes, RFID tags can be read in bulk, at a distance, and without line-of-sight, making them ideal for improving inventory management, verifying authenticity, and ensuring regulatory compliance. This introductory blog post breaks down how RFID works, the different types of tags, and why it’s especially valuable in meeting U.S. DSCSA and EU FMD requirements for unit-level traceability. As the series continues, it will explore how RFID supports compliance, standardization, and practical implementation across healthcare logistics.
