10 documented steps · Scan the QR code with your phone
How it works
Four steps, from the factory to the buyer’s phone.
- 1
The company records
Production, testing, shipping, delivery: each step is written down by whoever performs it.
- 2
Signature and fingerprint
The step receives the company’s signature and a unique fingerprint: changing even a comma would make it different.
- 3
Public ledger
The fingerprints are fixed on a public ledger that no one can rewrite. The data stays private.
- 4
Anyone can verify
Scan the QR code on the product, read its story and check with one button that nothing has been changed.

Who it is for
Scan the QR code on the product, read its story and check with one button that nothing has been changed.
Manufacturers
They prove the origin, quality and compliance of what they make, with documents no one can dispute.
Supply chain and distribution
Each party adds its step; transfers of ownership stay on record, with who transfers and who receives.
Consumers
They scan the QR code and see where the product comes from and the route it has taken, without registering.
Supervisory bodies
With authorised access they also see the restricted data and verify it themselves, without depending on anyone.
The European Digital Product Passport
Regulation (EU) 2024/1781 on ecodesign introduces the digital passport: a unique product identifier, a data carrier such as a QR code, and data accessible according to the role of whoever consults it. This platform is built on these three elements.
What goes on the public ledger, and what does not
On the public ledger
- Fingerprints only: character strings from which the data cannot be reconstructed.
- The date on which they were fixed.
Never on the public ledger
- Supply chain data, documents and attachments.
- Commercial data and personal data.
Verify without trusting us
Download the verifier: a single file that works on your computer, disconnected from this platform, and compares with the public ledger by itself.
Connected to business systems
Steps can arrive straight from business systems, with no manual entry; when anchoring is confirmed the system receives a signed notification.
Frequently asked questions
Does my data become public?
No. Only fingerprints go on the public ledger. The passport page shows the data the company has chosen to make public; restricted data is seen only by authorised parties.
Can a mistake be corrected?
Yes, but without deleting anything: a correction linked to the wrong step is added. Viewers see the original, the correction and the link between the two.
What happens if someone changes the data?
Verification fails: the recomputed fingerprint no longer matches the one fixed on the public ledger. You can see it in “Try it yourself”.
Do I have to trust this platform?
No. Each step can be downloaded with its proof and checked with the independent verifier, directly against the public ledger.
Do I need an app to read the passport?
No. Your phone camera is enough: the QR code opens a web page in Italian, English, French or German.
