How to Verify the Authenticity and Ownership of a Digital Product Passport

Follow the blockchain record from smart contract to physical asset and establish a complete chain of trust.

A Digital Product Passport (DPP) is represented by an NFT on a blockchain. The NFT contains a reference to a passport file in JSON format, stored online and linked to a specific physical or digital asset.

Start Verification
What You Can Verify

Five checks connect the digital record to the real asset.

  • The asset is authentic.
  • The passport belongs to the asset you are inspecting.
  • Who currently owns the passport.
  • Which brand or creator issued the passport.
  • Which organization deployed the smart contract.
01

Locate the NFC tag or QR code and scan it with the Beligent scanner

Obtain the NFT identifier from the product, packaging, QR code, NFC tag, website, or marketplace listing.

The NFT record will provide:

  • The smart contract address.
  • The token ID.

Scanning the NFC tag or QR code with the Beligent scanner will automatically retrieve all the passport information.

02

Verify the Smart Contract

After scanning the NFC tag or QR code with the Beligent Scanner, open the passport details page and find the link to the passport on a blockchain explorer.

Check:

  • The contract address matches the official address published by the brand or ecosystem.
  • The contract creator/deployer is the expected service provider or issuing authority.
  • The contract is verified and publicly readable, if applicable.

This confirms that the passport originates from the legitimate DPP infrastructure.

03

Verify the Brand or Creator

After scanning the NFC tag or QR code with the Beligent Scanner, open the passport details page and find the link to the passport on a blockchain explorer.

Confirm:

  • The creator is the first owner. Check that the recorded creator address matches the expected manufacturer, artist, or issuer.

This establishes who originally issued the passport.

05

Verify That the Passport Matches the Asset

The passport contains information describing the asset, including high-resolution images.

Compare:

  • Physical appearance.
  • Serial numbers.
  • Unique markings.
  • Manufacturing information.
  • High-resolution photographs contained in the passport.

Confirm that the asset in your possession matches the asset described in the passport.

This verifies that the passport belongs to the specific asset being inspected.

06

Verify Current Ownership

Thanks to the Beligent Scanner, find in passport details the link to the passport on a blockchain explorer. The blockchain records the current owner of the NFT. Check the owner field of the token.

Compare the recorded wallet address with:

  • The wallet claiming ownership.

If the addresses match, the blockchain confirms ownership of the passport.

07

Review the Verification Chain

A valid Digital Product Passport should provide the following chain of trust:

  1. 01

    The smart contract was deployed by the authorized deployer.

  2. 02

    The Digital Product Passport was minted by the authorized brand or creator.

  3. 03

    The passport file hash matches the hash stored on-chain.

  4. 04

    The passport content matches the asset being inspected.

  5. 05

    The NFT owner recorded on-chain matches the claimed owner.

When all five checks succeed, you can have strong confidence in the authenticity of the passport, the identity of its issuer, and the ownership of the associated asset.
