Tagless DPP issues an EU-compliant Digital Product Passport for a luxury or fashion item and binds it to the item itself, so the passport is retrieved by looking at the product rather than at something attached to it. A tag can be cut off, copied, or moved to a counterfeit. Our system derives an identity signature from the object's manufacturing detail: stitch geometry, tooling marks, material grain. The object becomes its own credential. Tags are supported; the passport does not depend on them. A fine-tuned vision-language model determines authenticity and produces the signature. The result is anchored on a public L2 as a non-transferable token, with evidence in distributed storage that anyone can verify independently. Each later event (resale, repair, recycling) issues an additional linked token, so the passport accumulates rather than ending at first sale. For brands, compliance. For owners, a product whose history survives them.
