EU Business Wallet and Digital Product Passport: Why the Integration Matters for Compliance and Trust

In brief: The EU Business Wallet (EBW, under eIDAS 2.0 from 2027) verifies who a company is. The Digital Product Passport (DPP, under the ESPR) verifies what is inside a product. Both proofs rely on verifiable credentials and belong together technically: a DPP is only as trustworthy as the identity of the party that issued it. Companies that address both requirements on the same standards base, rather than separately, avoid duplicate infrastructure and are prepared for the next wave of regulation.

What Is the EU Business Wallet (EBW)?

The EU Business Wallet is the digital identity for companies under eIDAS 2.0, the European Digital Identity Regulation. It allows organizations to verify themselves across the EU and prove their role in a transaction, for example as manufacturer, importer, or distributor. Rollout is planned for 2027.

What Is the Digital Product Passport (DPP)?

The Digital Product Passport is a data record for an individual product, required under the ESPR (Ecodesign for Sustainable Products Regulation, EU 2024/1781). It documents material composition, origin, reparability, and compliance information in a machine-readable, verifiable format. Introduction is happening sector by sector, starting with product groups under the Battery Regulation (EU 2023/1542).

Why Separating Identity and Product Data Is a Risk

A DPP can be technically signed correctly and still fail on one open question: is the identity of the issuing economic operator as verifiable as the product data itself? For buyers, market surveillance authorities, and downstream supply chain partners, that is not an academic detail. It is the difference between a compliance record that holds up in an audit and one that still requires manual research into who stands behind the data.

For companies with operations across several member states, or with complex supply chains, this adds up quickly. Every additional gap between identity verification and product data has to be bridged manually, where an automated check should sit instead.

How EBW and DPP Work Together Technically

Both systems rely on Verifiable Credentials, digitally signed claims that any authorized party can check cryptographically without contacting the issuer directly. When an economic operator already holds a digital identity based on Verifiable Credentials, a Digital Product Passport can build directly on it instead of establishing its own basis for trust:

• The DPP references a verifiable issuer.

• The issuer references its EBW identity.

• The full chain remains auditable, without a regulator or business partner having to contact the issuer individually.

This is the practical core of digital trust as infrastructure: identity, product data, and evidence chains rely on the same standards and remain interoperable, so compliance automation does not have to be rebuilt for every new regulation.

How Spherity Positions VERA and EIDA for This Integration

Spherity addresses both sides of this chain with two dedicated products built on W3C DID/VC and Self-Sovereign Identity (SSI):

• VERA is Spherity's platform for digital product passports. Every product receives a DID along with signed, verifiable claims covering material, origin, compliance, and sustainability, which any authorized party can verify cryptographically.

• EIDA provides the identity layer for eIDAS 2.0 and the EU Digital Identity Wallet, which organizations use to prove their role in a transaction.

Technical integration of DPPs with EU Business Wallet standards, particularly along UNTP (UN Transparency Protocol) specifications, is currently an active research project at Spherity, not yet a shipped product capability. Companies already using VERA for their DPP obligations and EIDA for their identity requirements are on the same technical foundation once EBW integration is standardized and rolled out.

Frequently Asked Questions About the EU Business Wallet and Digital Product Passport

When will the EU Business Wallet become mandatory? 

Rollout of the EU Business Wallet under eIDAS 2.0 is planned for 2027.

Which products fall under the Digital Product Passport first? 

The DPP is being introduced sector by sector under the ESPR, starting with product groups under the Battery Regulation (EU 2023/1542), followed by textiles, automotive, and construction.

Why isn't a signed DPP enough on its own? 

Because the signature only confirms the data has not been altered, not whether the issuing organization is actually who it claims to be. That requires a verifiable identity, which is what the EBW provides.

Next Steps

For companies in the battery, textile, automotive, or construction sectors preparing for ESPR deadlines, it is worth looking at both layers at the same time: product data and organizational identity. Isolated solutions mean duplicate infrastructure. A shared, verifiable standards base carries the next wave of regulation as well.
