1. Product batch identification: It allows identification of specific product batches, even down to the level of individual serialized products. This adds the ability to link to product origin, recall and/or expiration date information. |

|
2. Supply chain monitoring: Through GS1 Digital Link, products can be digitally identified and tracked throughout the supply chain, thereby improving the transparency and efficiency of the supply chain. |
3. Data richness: GS1 Digital Link can include more data, such as product attributes such as weight, size, and expiration date, which are found by scanning the URI to find the product's digital identity and related information. |

|
4. Dynamic information updates: Brand owners can continuously update digital content without changing the QR code of the GS1 Digital Link URI on product packaging, which means that even new promotions or usage ideas do not require changes to the packaging or Art work. |
5. Leveraging global standards: Using GS1 Digital Link means you're not just providing a URL for people to scan, you're also providing a GS1 identifier – the same identifiers relied on across the industry today – and leveraging open global standards . |

|
Overall, GS1 Digital Link provides products with a unique digital identity, which lays the foundation for an IoT environment where smart products become the norm. This has huge implications in packaged goods, retail, healthcare and other industries. |
The structural format of GS1 Digital Link follows a standardized structure and specifically includes the following parts: |
1. Domain Name - An Internet domain name owned by a brand or company. 2. Primary ID Key - GS1 Application Identifier (AI), indicating the type of identifier used, such as GTIN-13, GTIN-14, SSCC, etc. 3. Identifier - the actual product identification number based on the AI key. 4. Qualifier - Optional additional ID, such as batch number, serial number, etc. |

|
In addition, the construction of the GS1 Digital Link URI includes the order of path elements, the construction of the query string, and how the GS1 keys and values are concatenated. |
