GS1 Digital Link 1.3 is a GS1 standard that defines how to encode GS1 identification keys — such as the GTIN, GLN, and SSCC — as web URIs inside QR codes. It enables a single QR code to act simultaneously as a machine-readable product identifier for point-of-sale scanning and as a gateway to digital content, including product pages, traceability records, and authentication services. By expressing identifiers in a standardized URL structure, GS1 Digital Link bridges traditional retail barcoding with the web, letting one symbol serve consumers, supply-chain systems, and e-commerce alike. Widely applied in retail, food, and healthcare, it connects physical products to online information and represents GS1's framework for migrating from classic barcodes toward web-enabled, QR-based product identification.
