What the record is worth after the factory gate
A passport states what was made. Its value continues through the years afterwards: helping a technician prepare for a visit, supporting a warranty claim, giving a financier condition evidence to assess, or helping another project consider a reclaimed beam. Over those years, owners, service contractors, technicians and receiving projects each need part of that history. A continuing record helps them work from the same evidence.
Why keep the record
Two reasons exist to keep a product record, and they attract different buyers. One is the obligation: Regulation (EU) 2024/1781 (Ecodesign for Sustainable Products, ESPR) and Regulation (EU) 2024/3110 (Construction Products) put a passport in front of one product group after another as their delegated acts and harmonised specifications arrive. Preparing the required evidence takes time; applicability and dates must be checked for the particular product.
The other reason is the work that the same record can support. A property owner wants the fault diagnosed before the van is dispatched. A manufacturer that retains title under a lease wants to know where its units are and what condition they are in. A deconstruction contractor wants to sell a component rather than pay to landfill it. None of those depend on a regulation, and all of them want exactly the payload a passport plus a logbook holds.
The four jobs after the gate
Each of these has its own page, with its own worked example.
For the property owner and the service contractor who answer faults for a living: the report, the technician who was permitted to act on it, the work actually performed and the measurement that evidences the state it was left in — logged against the asset itself so the next team can find the relevant history alongside its own work-order records.
For whoever is accountable for a building: one place where the property, its spaces, its systems and the equipment inside them keep their maintenance, inspection and renovation history. It starts from whatever is on hand — a tag, a location, a photograph — rather than from a survey that has to be funded first.
For the manufacturer that stands behind one unit and the owner who operates it: the events of a single product's working life attached to that product's own identity, so the history stays readable when the unit changes hands, changes building, or begins a second life somewhere else entirely.
For the deconstruction contractor and the project receiving what comes out: what a removed component is, what condition it is in, how confident that assessment is, and when it can actually be lifted out — kept with the item into its next use instead of discarded with the building.
Leasing and product-as-a-service
For a manufacturer offering a lease or service contract, location, condition and maintenance history help assess service needs and residual value. A passport and logbook can supply part of that evidence. Financing and insurance still depend on the counterparty's assessment, contract and wider risks.
Retaining ownership can give a manufacturer a stronger reason to maintain a product and recover it for another use. The record can support that business model; it does not establish durability, financial viability or regulatory compliance by itself.
The resolvable product identity a leased unit is tracked by runs today. Per-use billing against verified events, and the condition evidence a financier or an insurer underwrites, are later applications of that continuing record.
Who uses the record, and why
- For whom
- Anyone who owns the consequences of a product after the sale: property owners and facility managers, maintenance contractors and the technicians they send, manufacturers that retain title under a lease or a service contract, deconstruction contractors, and the projects that receive what those contractors remove.
- Why
- Maintenance and reuse decisions need specific answers: which unit is this, who last serviced it, is its warranty still valid, and who was authorised to work on it? Recording that information when the work happens gives later teams evidence to consult when assessing condition, responsibility and possible reuse.
- What it costs
- Nothing today. Passport issuance, the resolver, the sandbox and the wallet are published at no cost, with no card and no sales call; what is being prepared is stated on pricing.
- What you gain
- Resolvable asset identifiers, a linked product history and condition evidence that remains available through changes of custody. Together, these can support discussions about leasing, take-back and resale.
What you can use today
- A passport issued against its product group's shape The battery group has a wired shape, and issuance is gated on it. Issue one.
- A product identity third parties can resolve An issued product gets its own DID and a typed link-set of its credentials, reachable server-side through the resolver.
- Credentials issued to and presented from a wallet Issuance and presentation run against the pre-seeded test tenant, whose keys reset on every restart, so credentials from it suit integration work. Run a round trip.
Each of these is on Facts with the URL or file that settles it. The event log, delegated mandates, reuse matching and per-use billing are not presented as public capabilities. The identity layer underneath all of it is described on digital product passports.
