How QR-verifiable batch records work.
A QR-verifiable batch record links a printed code on packaging, an invoice or a supplier website back to a hosted record that shows the current documentation status, history of revisions and source of the underlying CoA.
What the QR encodes
- • The public verification URL for the batch record
- • The certificate ID and batch number can be reconciled visually
- • The QR does not contain product safety, dosing or use guidance
- • The QR is a pointer to documentation, not an endorsement
What the record shows
- • Compound label, supplier, batch number and certificate ID
- • Test date, method, lab status and chain-of-custody
- • Document fingerprint / checksum and timeline events
- • Conservative status labels including expired, disputed, retested, superseded
How records change over time
- • Documents can be retested and re-uploaded
- • Original records remain visible and marked superseded
- • Disputes are displayed rather than hidden
- • Hash changes are recorded as audit events
What QR records do not do
- • Do not certify safety, legality, efficacy or approval
- • Do not provide dosing, protocol or treatment guidance
- • Do not replace independent jurisdiction-specific compliance
- • Do not represent suitability for human or veterinary use
