GS1 Digital Link Standard https://www.gs1.org/standards/gs1-digital-link
The GS1 Digital Link standard extends the power and flexibility of GS1 identifiers by making them part of the web. That means that GS1 identifiers, such as the GTIN, are now a gateway to consumer information that strengthens brand loyalty, improved supply chain traceability information, business partner APIs, patient safety information and more. Where a URL typically points to a single, specific website, GS1 Digital Link enables connections to all types of business-to-business and business-to-consumer information. If you’re adding a QR code or NFC tag to a product, using the GS1 standard means you’re not only providing a URL for people to scan, you’re also carrying GS1 identifiers – the same identifiers relied upon throughout industry – and following a non-proprietary, no vendor-lock system. This means the brand owner remains in complete control but can still link to any number of information sources, all from one symbol, saving space and improving efficiency.
