Technical standards & interoperability

The standards our platform is built on

Products with QR codes — the technical standards of the Digital Product Passport

Built on the open standards of the DPP ecosystem

A Digital Product Passport only works if it is interoperable — with the EU registry, with GS1 identifiers and with your partners' systems. WIARA's platform is built on the open standards of the ecosystem, so you are not locked into one solution and your passports can be read everywhere.

Key capabilities

Technical standards & interoperability

EU registry & registration

Integration with the EU's central registry, passport registration and beta access — ready for the day the obligation starts.

GS1 identification

GS1 Digital Link and GTIN ensure every passport is uniquely identified and reachable via a standard QR code.

Open REST API

Full programmatic access to connect passports with your ERP, PLM and production systems.

Role-based access

The public, economic operators and market surveillance authorities see different data with appropriate rights — authorities via eIDAS.

Standards & interoperability

Frequently asked questions

Question Mark Section Supporting Image

Yes. The platform is ready to integrate with the EU DPP Registry and registers passports, including access to the beta environment ahead of the obligation dates.

GS1 Digital Link is a standard way for a single QR code to point to a product's passport. We use it so the data carrier is interoperable and valid for the product's whole life.

EPCIS 2.0 (supply-chain traceability events) is on our roadmap. The basic passport does not require EPCIS; for traceability-heavy sectors we plan it as an extension.

Through role-based access. Market surveillance authorities log in via eIDAS (the European digital identity) and see the data intended for them, separate from the public and professional views.

Yes, we offer a REST API for programmatic access, so passports connect directly to your ERP, PLM or production systems.
