To meet the stringent tracking requirements of the Drug Supply Chain Security Act (DSCSA), pharmaceutical companies must adopt secure and interoperable product identification systems. This blog post outlines how open RFID standards—specifically GS1 EPC and RAIN RFID—enable scalable, compliant drug serialization across the entire supply chain. GS1 embeds complete product data directly on RFID tags, eliminating database dependencies and simplifying compliance. RAIN RFID offers a hybrid model using third-party lookups while maintaining global compatibility. Compared to proprietary systems, these open standards reduce vendor lock-in, enhance transparency, and ensure long-term regulatory alignment—especially critical as the DSCSA 2024 electronic tracing deadline nears.
