What does QR code mean?
QR code is the machine-readable matrix code that links users, operators, or authorities to information required by the Battery Regulation. It is also the visible scan point in many battery-passport and product-passport workflows: it may encode a URL, identifier, or lookup reference, but compliance value depends on the governed record, role-based access, and evidence behind the scan.
Short version
A QR code is a machine-readable matrix code that links a physical battery or product to required digital information. It is the visible gateway to the record, not the passport itself, not the unique identifier, and not proof of compliance on its own.
Minespider working definition
A QR code, or Quick Response code, is a two-dimensional matrix barcode used as a physical access mechanism. Attached to a product, battery, packaging, label, or accompanying document, it can encode a secure URL, unique identifier, or lookup reference that routes a scanner to the relevant digital compliance record. In battery-passport and DPP architecture, the QR code is the visible access layer. It does not define the passport data structure, create the unique identifier, enforce the access-rights model, or guarantee the validity of the data it connects to.
Common boundary mistakes
The main implementation mistake is to treat the scannable square as the passport. The QR code is the key or doorway; the passport is the structured electronic record behind that doorway. The QR code is also not the unique identifier. It may carry or resolve an identifier, but the identifier is the value that distinguishes the asset, product model, batch, item, or battery. A printed code is not compliance evidence by itself, because a code can be generated without complete data, proper audit trails, supplier evidence, lifecycle updates, or permission controls.
Access and permissions
Scanning the same QR code should not be read as everyone seeing the same passport content. A consumer, repairer, recycler, customs official, market surveillance authority, and economic operator may enter through the same visible code but receive different fields or assurance levels based on role-based access, authentication, authorization, and legal disclosure rules. The QR code provides the entry point; the passport system decides what the scanner can see.
Source context
The EU Battery Regulation defines QR code as a machine-readable matrix code that links to information required by the Regulation. Article 13 and Article 77 set the operational context for battery information and battery-passport access: relevant batteries must bear a QR code that is printed or engraved visibly, legibly, and indelibly where possible, with access to the battery passport required from 18 February 2027 for covered battery categories. DIN DKE SPEC 99100 is useful as implementation context for battery-passport data and access architecture, but the binding legal definition comes from the EU Battery Regulation.
What this means for implementation
Printing the QR code is the last-mile access step, not the first compliance task. Implementation work should start with a reliable data chain, product or battery identity model, access-rights model, and resolution architecture. The physical code then has to remain scannable, persistent, and, where the EU Battery Regulation applies, printed or engraved visibly, legibly, and indelibly over the product or battery lifecycle. Teams should plan for print quality, engraving or label method, placement, abrasion, heat, chemicals, replacement labels, redirect governance, backend migrations, offline handling, cloned codes, unreadable codes, and fallback access if the original carrier fails.

Definition status
Reviewed public draft page. Aligns with identity/access policy: separates identity, carrier, QR/access mechanism, passport record, item granularity, and service-platform infrastructure.
Practical application
Implementation records should capture code payload, resolution target, print or engraving specification, placement location, scan-quality check, linked battery or product identifier, redirect rule, access-control outcome, replacement procedure, lifecycle durability test, and fallback route for damaged or unreadable codes.
Minespider commentary
QR code is often treated as shorthand for the passport itself, but the code is only the visible access mechanism at the edge of the passport stack. If the evidence behind it is stale, incomplete, or linked to the wrong battery, the scan creates confidence without substance; the scan should be linked to identity, permissions, evidence freshness, and fallback handling.
Common confusions
- Treating the QR code as the battery passport or digital product passport itself.
- Treating a printed QR code as proof that the linked data is complete, accurate, current, or permissioned correctly.
- Confusing the QR code with the unique identifier; the code is the machine-readable carrier, while the identifier distinguishes the asset or product scope.
- Assuming every scanner sees the same data; role-based access and selective disclosure can change the visible fields after the same code is scanned.
- Assuming QR-code generation solves lifecycle access; physical durability, link persistence, redirects, replacement procedures, and fallback routes still need governance.
