GS1 Digital Product Passport
What is a Digital Product Passport?
A Digital Product Passport (DPP) is a structured digital record that travels with a physical product throughout its lifecycle. It contains verified information about a product's materials, manufacturing origin, environmental impact, certifications, and end-of-life options.
DPPs are designed to be:
- Machine-readable — structured JSON-LD that systems can parse and verify
- Publicly accessible — retrievable by anyone scanning a QR code
- Cryptographically signed — tamper-evident with a verifiable digital signature
- Interoperable — based on open standards (GS1, UNTP, W3C)
EU ESPR Regulation
The European Union's Ecodesign for Sustainable Products Regulation (ESPR) mandates Digital Product Passports for product categories sold in the EU market. Rollout begins in 2026 and will cover textiles, electronics, batteries, and other categories.
ESPR requires that DPPs be:
- Accessible via a GS1 Digital Link QR code on the physical product
- Stored on a system that guarantees long-term accessibility
- Signed to ensure data integrity
TrackVision generates ESPR-compliant DPPs automatically from the data you collect from your suppliers.
Standards
TrackVision DPPs are built on three open standards:
GS1 Digital Link
GS1 Digital Link is the standard that connects physical products (via GTIN and QR codes) to digital information. A GS1 Digital Link URL encodes the product's GTIN and optional qualifiers (batch, serial) in a structured URI:
https://resolver.acme.trackvision.ai/01/09506000134352
https://resolver.acme.trackvision.ai/01/09506000134352/21/SN-001
UNTP (UN Transparency Protocol)
The United Nations Transparency Protocol defines the data model for Digital Product Passports. TrackVision implements the UNTP Digital Product Passport (DPP) conformance profile.
W3C Verifiable Credentials v2
W3C Verifiable Credentials provides the cryptographic signing framework. Each DPP is issued as a Verifiable Credential with an Ed25519 signature, making it possible for anyone to verify the issuer and confirm the data has not been tampered with.
How TrackVision Implements DPP
-
Supplier data collection — TrackVision sends data requests to your suppliers. They submit materials, certifications, facility details, and compliance documents through a dedicated portal.
-
AI-assisted research — TrackVision's AI fills in publicly available data (environmental standards, regulatory status) and highlights gaps.
-
DPP generation — TrackVision assembles the collected data into a JSON-LD Verifiable Credential conforming to GS1 and UNTP schemas.
-
Signing — The DPP is signed with your account's Ed25519 private key. The corresponding public key is published at
/.well-known/did.jsonso anyone can verify it. -
Resolution — When a consumer scans the QR code, the resolver checks the
linkTypeparameter and either redirects to the product page or returns the DPP JSON-LD.
