Luxury Goods and
Digital Product Passport

Enter a passport's GTIN, its model reference, material composition, and repairability note, a revision index, and up to three handovers, each a from party, a to party, and a day. This tool checks the GTIN's mod-10 checksum, confirms the three required attributes are filled in, and walks the handover chain for custody breaks and out-of-order days, then fingerprints the passport and the lineage separately so a buyer can re-derive the item's whole history instead of trusting a label. Bump the revision index and the passport digest changes with it, so revision two of the same item leaves its own fingerprint rather than quietly overwriting revision one.
