This digest covers the version, SKU, batch number, supplier, document URL and document fingerprint. It is separate from the document fingerprint.
A document fingerprint or matching blockchain record does not independently establish the authenticity, composition, safety, efficacy or approval of a physical product. Compare the batch on the package and review the underlying supplier and laboratory evidence.
