What Customs Officers See When They Scan Your QR Code.

When a customs officer scans the GS1 Digital Link QR code on your battery, they see the public DPP viewer — a read-only page showing your passport data, registry status, and compliance information.

The public viewer

The public viewer is a web page that loads when anyone scans or clicks a GS1 Digital Link URL. It does not require a EU Digital Passport Processor account or login. It is designed for three audiences: customs officers checking compliance at the border, market surveillance authorities investigating products, and anyone else with access to the QR code.

What is shown

The public viewer displays the following sections:

Header — Battery name, passport number, battery category (EV / Industrial / LMT), and economic operator name.

Registry status — Whether the passport is registered with the EU DPP Registry. Customs officers check this first. A green "Registered" badge means the battery is compliant. An amber "Not Registered" badge means the battery has not been submitted to the registry — this will trigger further inspection.

Compliance strength — The BASIC / GOOD / STRONG / VERIFIED indicator showing the overall data completeness and verification level of the passport.

Annex XIII data — The passport's technical data, organised into the same four sections as the creation wizard (Identity & Origin, Performance, Sustainability, Supply Chain). All required fields are shown; optional fields appear if populated.

Supply chain actors — The economic operators involved in the battery's lifecycle, with their roles and verification status.

Carbon footprint — The declared carbon footprint value and performance class (when available).

QR code and identifier — The GS1 Digital Link URL and passport number for reference.

What is not shown

The public viewer does not show:

• Internal EU Digital Passport Processor data (team members, account settings, billing).
• Draft or in-progress data that has not been activated.
• Edit history or version logs.
• Contact details of the economic operator beyond the registered legal name.

Revoked passport view

If a passport has been revoked, the public viewer displays a "This passport has been revoked" notice instead of the full data. The notice includes the passport number and a statement that the battery's DPP is no longer active. Customs officers will treat this as a non-compliant battery.
