How Device Passports work

A Device Passport is the verified history of a device — what was repaired, with which parts, and when. It is built as the work happens, sealed so it can’t be quietly changed, and it carries no personal information.

Why it exists

When you buy a used device or pick one up after a repair, you usually have to take someone’s word for what happened to it. The Passport removes the guesswork: the history is recorded plainly, kept with the device, and easy to check — so the next person never has to wonder.

How it works

It records the work, not the owner

A Passport is a running record of what was done to a device — the repair, the part, the diagnostic, the date. It is tied to the device’s hardware identity (its IMEI or serial number), never to who owns it.

It is built automatically

When a shop completes a repair on the platform, the entry is written for you — the repair type, the parts used, the date, and the technician’s certification level at that moment. No extra data entry, no chance to forget.

It cannot be quietly rewritten

Every entry is sealed with a cryptographic fingerprint and chained to the one before it. Entries are added, never edited or deleted — a correction is recorded as a new note, and the original stays in place. If a link in the chain were altered, it would show.

It travels with the device

When a device changes hands, its Passport stays with it. The next owner sees the full history; the previous owner’s personal details do not carry over. The record is the device’s, not any one person’s.

What a Passport never shows

Who owns the device. Ownership is account information, kept separate. The Passport is about the device, not the person.
The shop’s identity, in the open record. Shops are shown as an anonymous reference in the public history.
What anything cost. Pricing is never part of the device’s public record.

Common questions

Can I look up a device before I buy it? Yes. Once you’re signed in, you can look it up by its IMEI or serial number and see its history — no personal details, just the device’s record. A seller can also share a direct link to a device’s history with you.
Can a shop change or remove a repair record? No. Entries are permanent. If something needs correcting, a note is added; the original entry remains.
A device was reported lost or stolen — can that be removed? Only our support team can clear that flag, after reviewing the case — not a shop, and not automatically.
