What Is a QR Code
In iTraceiT, every parcel, stone or jewelry piece is represented by a QR code. This QR code is the digital identity of the item. It contains all the information that describes its origin, history, transformations and movements throughout the supply chain
A QR Code is the core element that enables traceability in iTraceiT. It is the digital link between a physical product and its traceability data, allowing each step of the supply chain to be documented, verified, and shared. Without QR Codes, traceability cannot exist, as they are the foundation that connects products, data, and actors in a single continuous workflow.
In iTraceiT, QR Codes are used to represent products, parcels, or batches and to ensure transparency, accountability, and data continuity across the supply chain.
What a QR code Represents
A QR code in iTraceiT is not just an image. It is a unique digital identity that carries all the information related to a specific parcel or item. It acts as the link between the physical object and its digital traceability record. When you create a parcel, the system generates a QR code that becomes the permanent identifier for that asset.
A QR code can include:
- Item description
- Origin information
- Weight, shape or number of stones
- Certificates and grading reports
- Audit documents
This digital identity stays with the item for its entire lifecycle.
How QR Codes are used in the traceability workflow
QR Codes are created at the beginning of the traceability process or imported when they are received from another actor. Once created, they become the central object used to manage traceability operations.
Throughout the workflow, QR Codes can be enriched with data, updated with documents, and transformed to reflect real operations such as splitting, merging, or grouping parcels. Each action performed on a QR Code contributes to building a complete and chronological traceability record.
When a QR Code is shared or published, it allows traceability to continue across domains while clearly identifying who added which information and at which stage.
QR Codes and data responsibility
Each QR Code carries the responsibility of the actor who manages it at a given moment. When data is added or updated, it is clearly associated with the domain that performed the action.
When a QR Code is exported on the blockchain and transferred to another actor, responsibility is formally passed on. This ensures transparency, accountability, and trust between all parties involved in the supply chain.
A QR Code is the central building block of traceability in iTraceiT. It creates a reliable digital identity for products, connects data across actors, and preserves the full history of operations. By using QR Codes, companies can ensure transparent, structured, and trustworthy traceability throughout their supply chain, while preparing each product for validation, sharing, and certification in the next steps of the workflow.
