GS1 Digital Link URI Architecture
1. Standard Overview & Core Architecture
GS1 standards provide the global framework for unique product identification. With the transition to 2D barcodes and GS1 Digital Link URIs, physical product packaging connects seamlessly to digital cloud registries, enabling full compliance with EU Digital Product Passport (DPP) regulations (ESPR, Battery Regulation) and global retail point-of-sale standards (Sunrise 2027).
2. Key Specifications & EN Standard Alignment
Passmith is built directly on European CEN/CENELEC standards EN 18216 through EN 18223 for Digital Product Passports:
- EN 18219: Identifier types (product GTIN, operator GLN, facility GLN).
- EN 18220: Data carriers (QR code, Data Matrix with GS1 Digital Link).
- EN 18221: Persistence & decentralized resolver protocols.
During the 2025–2027 transition period, printing both traditional 1D barcodes and 2D GS1 Digital Link QR codes (dual marking) ensures zero disruption at legacy retail checkouts while ensuring full compliance with EU regulations.
3. Next Steps & Enterprise Readiness
Brands, manufacturers, and importers selling in the European Union should audit GTIN master data, configure resolver domains, and prepare packaging artwork prior to mandatory deadlines.
