From a physical product to its digital record.
A Digital Product Passport connects a physical product with its identity, documents and lifecycle information. A product identifier gives owners and other readers a direct path to that record.
Architecture
Identity, information and evidence.
A product identifier links a physical item with digital information. Documents and lifecycle events provide context, while evidence helps readers assess the record.
The layers
Four layers, from the object to the proof.
Each layer connects the physical product with the details people need to understand, care for and pass on the item.

A cryptographic fingerprint can help compare a file with a recorded value. This check supports a review of file integrity; it does not establish that the product details are accurate or the item is genuine.
01
Create a fingerprint
A cryptographic hash represents a file or record without exposing its contents.
02
Record evidence
A trusted timestamp or ledger entry can associate the fingerprint with a point in time.
03
Compare
A reader can compute the file's fingerprint again and compare it with the recorded value.
