GS1 System
The GS1 System is not a single barcode but a globally governed ecosystem of symbologies, identifier standards, and data structures that enable seamless supply chain communication across industries and borders. GS1's Application Identifiers (AIs) allow structured metadata — lot numbers, expiry dates, serial numbers, weights — to be embedded alongside product GTINs in a single scannable symbol, eliminating manual data entry at every handoff point.
