The identity layer
for physical products.
One identifier per product, carrying both what it is and whether it is real.
Two answers, one code.
Passport infrastructure — identity, structured data, disclosure by role, version history, machine access and continuity — and cryptographic authentication on the same identity.
We came to passports from the counterfeiting side, which is why we treat a product code as a root of trust rather than a link. It is also why our answer to "why should I believe this data" is a signature rather than a promise.
What the platform does →Both ends of the chain.
Operators in Europe
Importers, brands and representatives who carry the obligation and need the data behind it.
Manufacturers in Asia
Factories producing the data, binding identity on the line, and supplying European customers.
Institutions
Authorities, laboratories, repairers and recyclers reading the parts they are entitled to.
Three standing rules.
Say what is built. Implemented means implemented. Where a rule is still being written — and several are — we say that instead of designing around a guess.
Never claim a product is compliant. We prove what the information was and when. The declaration belongs to the operator.
Do not monetise the data. No benchmarking, no resale, no model training on what customers store with us.
