A two-dimensional symbol can serve as a data carrier where the applicable rules permit it, but the value lies in the governed information and lifecycle behind the destination. Avoid embedding large, changeable datasets directly inside a QR code.
A safer QR-linked architecture
- Create a unique, persistent, non-sequential passport identifier.
- Encode only a first-party HTTPS resolver URL in the QR where appropriate.
- Resolve that URL to the current approved passport version.
- Keep draft and private data outside the public projection.
- Support retired, replaced or recalled states without recycling the token.
- Generate accessible, high-contrast SVG and derived PNG assets and test physical scans.
Plan for the correct identifier scope
A scalable model should support product families, models or SKUs, batches or lots and serialised items. The appropriate level is not a product-design preference alone; it must be configured against the applicable product rules and operational traceability decision.
What QR generation does not prove
- It does not determine whether the product is legally in scope.
- It does not validate the data against applicable requirements.
- It does not prove identifiers conform to an unverified standard.
- It does not make private documents safe to publish.
- It does not provide certification or regulatory approval.
