GS1 Digital Link: Compare

GS1 Digital Link gives product identifiers a standard form inside web addresses. For a fashion brand, a QR code can connect a garment's GTIN, with optional batch or serial detail, to online information. A separate resolver specification supports several destinations from the same identity, such as care instructions or a product record; redirects can change without reprinting the code. Brands still need to decide what the identifier represents, who maintains the linked information and how to check its accuracy. Digital Link supplies identification and linking conventions. It neither defines a complete digital product passport nor certifies the sustainability claims attached to one.
