At a glance
A useful digital record connects the delivered profile to its manufacturing and quality evidence. A QR code is only an access mechanism; it is not proof that the underlying information is complete or correct.
Key points
- Batch genealogy can link raw-material lots, recipe revision, line conditions and inspection decisions.
- Define which identifiers remain on the product and which records are available to each user.
- For buyers, request practical traceability rather than a technology slogan.
Technical context #
Batch genealogy can link raw-material lots, recipe revision, line conditions and inspection decisions. The system should preserve the relationship when boards are cut, repacked or supplied through a distributor.
What to measure and document #
Define which identifiers remain on the product and which records are available to each user. Test retrieval from an actual delivered pack. Keep revision history and access controls so a later change does not silently rewrite the evidence for an earlier delivery.
Implications for development and specification #
For buyers, request practical traceability rather than a technology slogan. Ask how a complaint, recall or replacement order is linked to the original batch. Do not label a system a statutory digital product passport unless that claim is independently justified.

Common questions
What evidence is needed for digital batch genealogy for WPC profiles?
Define which identifiers remain on the product and which records are available to each user. Test retrieval from an actual delivered pack. Keep revision history and access controls so a later change does not silently rewrite the evidence for an earlier delivery.
