Repair Passport · currently being validated
The verified history of the things you own.
Not everything in a passport is verified. Each record shows what it is: an owner's claim, a claim with evidence attached, or a claim that someone else has checked. A passport never certifies a product or a complete history.
Repair Passport organises a product's repair records, the evidence behind them, a separate trust state for each record, what you choose to share, and the history of who has held the passport.
Repair Passport is not yet available as a service. “I want a Repair Passport” only tells us you are interested: no account, no payment, no email.
How Repair Passport works
Create a passport
Start a private passport for a product you own: what it is, the brand and model, and when you bought it.
Record repairs and services
Add what happened: the date, the problem, the work done. Each entry is recorded as your claim.
Attach evidence
Keep an invoice or job sheet with the record. Attached evidence supports a claim; it does not prove it.
Share or hand on — your choice
Share selected parts read-only, revoke the link at any time, and pass the passport on when the product changes hands.
What a Repair Passport records
- Product identity — category, brand, model, an optional serial number and purchase date.
- Repair and service records — date, reported problem, work performed, parts, repairer, cost and warranty, as far as they are known.
- Evidence — whether a document such as an invoice is attached to a record.
- A trust state for each record — kept separate from the record and from its evidence.
- Sharing history — what was shared, when, and whether the link was revoked.
- Ownership-transfer history — who held the passport, and when it was handed on.
Anything nobody recorded is shown as UNKNOWN. A missing record never means “no repair”.
Claim ≠ Evidence ≠ Verification
Three different things that are easy to mix up. Repair Passport keeps them apart.
Claim
What the owner says happened, for example “the screen was replaced in March”.
Evidence
A document attached to support a claim, such as an invoice. Its presence alone does not prove the claim.
Verification
A check by someone other than the owner. A record is only verified if such a check actually took place.
Trust states describe one record at a time
- Owner reported
- The owner recorded it. Nobody else has checked it.
- Document supported
- In the concept: the claim is supported by documentation, not only by the owner's word.
- Repairer verified
- In the concept: the repairer who did the work has confirmed the record.
A trust state is not a certification, a safety guarantee, or a manufacturer or government approval, and it never covers a whole product. In today's prototype the higher states are simulated for testing: no document is checked and no repairer confirms anything.
What a buyer could see
- The owner chooses exactly which records and details to share, previews them, and only then creates a read-only link.
- A buyer sees each shared record together with its trust state, so a claim is never presented as more than it is.
- The owner's identity, serial number and the documents themselves are not shared — at most, that evidence exists.
- The owner can revoke the link at any time.
A buyer view shows only what the owner chose to share. Repairs that were never recorded, or not shared, will not appear — so a short history is not proof of a clean one.
When the product changes hands
The current owner can offer the passport to the next owner, who accepts it. From then on the new owner holds the passport, and its history — including the transfer — stays with the product.
Sharing and transferring are different. A share link gives read-only access and never transfers ownership. A transfer inside Repair Passport records who holds the passport; it is not legal proof of ownership.
