QR codes

Every published DPP on Traceable has a QR code. The QR code is the physical link between a battery product and its Digital Product Passport — it is the mechanism by which downstream users, regulators, and market surveillance authorities access the DPP data from the product itself.

How QR Codes Are Generated​

QR codes are generated automatically at the moment a product is published. There is no manual generation step. You do not need to request a QR code — it is created in the background as part of the publish workflow.

The QR code encodes the permanent public DPP viewer URL for the product:

https://app.traceable.digital/dpp/[slug]

This URL is stable. It does not change when you update and republish the product. The same QR code printed on a battery manufactured today will remain valid and will resolve to the current version of the DPP for the entire product's commercial lifetime.

Download Formats​

Traceable provides QR codes in two formats:

SVG (Scalable Vector Graphic)​

Use SVG for all print applications — packaging, product labels, datasheets, and certificates. SVG is resolution-independent: it can be scaled to any size without pixelation or quality loss. This is the format to send to your print supplier or packaging designer.

PNG (Portable Network Graphic)​

Use PNG for digital applications — websites, PDFs, email communications, and on-screen display. The PNG is exported at 1000×1000 pixels, which is sufficient for most digital use cases. For very large display formats, use SVG instead.

To download a QR code for a published product:

  1. Open the product record.
  2. Click QR Code in the product navigation tabs.
  3. Click Download SVG or Download PNG.

Minimum Print Size for EU Compliance​

The EU Battery Regulation 2023/1542 and the associated implementing acts specify requirements for the physical presentation of the DPP QR code on the battery label or packaging. The mandatory minimum dimensions are:

1 cm × 1 cm (10mm × 10mm)

This is the smallest size at which a standard smartphone camera can reliably scan the QR code. Printing below this size creates a risk that the QR code is unreadable, which constitutes a compliance failure under the labelling requirements.

Traceable's SVG download is structured with this minimum in mind. When placing the QR code in your label artwork:

  • Do not scale the QR code below 1 cm × 1 cm.
  • Maintain a clear white quiet zone (margin) around all four sides of the QR code of at least 4 modules (the small squares that make up the QR code). Traceable's SVG includes this quiet zone — do not crop it.
  • Print on a white or very light background. QR codes on dark or textured backgrounds significantly reduce scan reliability.
  • If the battery is too small to accommodate a 1 cm × 1 cm QR code (common for small portable batteries), the regulation permits placing the QR code on the packaging rather than on the battery itself, or on a document included with the product.

For batteries where physical size constraints make direct labelling impractical, consult the applicable implementing act for your battery category.

What the QR Code Resolves To​

Scanning the QR code opens the public DPP viewer — a clean, structured webpage that displays the DPP data in a consumer- and regulator-friendly format. The public DPP viewer shows:

  • Battery identity (name, model number, category, chemistry)
  • Technical specifications (capacity, voltage, energy content, mass)
  • Manufacturer information
  • Compliance and performance data (carbon footprint, state of health, where applicable)
  • Associated compliance documents (those marked as DPP-visible)
  • Verification status (whether third-party verification has been completed)
  • Blockchain anchor proof (if anchored — Phase 2 feature, see Blockchain Anchors)

The viewer does not expose internal notes, supplier data request details, or any fields marked as internal-only. It shows only the data explicitly designated for public display.

The viewer URL is accessible without login — any user, anywhere in the world, can access a published DPP by scanning the QR code or entering the URL directly. This is by design: the regulation requires DPPs to be freely and publicly accessible.

Bulk QR Code Download​

Phase 2 — Not yet available

Bulk QR code download is a planned feature. The QR Codes portfolio page in the Operator Portal currently shows a coming-soon state. Per-product QR code download (described above) is available today from each product's QR Code tab.

When the bulk download feature ships, you will be able to download QR codes for multiple products at once:

  1. Go to the Products list view.
  2. Select the products you want QR codes for using the checkboxes.
  3. Click Download QR Codes in the bulk action toolbar.
  4. Choose your preferred format (SVG, PNG, or both).
  5. Click Download. A ZIP file is generated and downloaded to your computer.

The ZIP file will contain one QR code file per product, named using the product's model number and Traceable ID (e.g., LFP-100-PROD-0042.svg). Products that are not yet published will be excluded from the ZIP with a notice in the summary report.

QR Code Scan Analytics​

Phase 2 — Not yet available

Scan analytics are a planned feature included in the QR Code Engine module, which is not yet active. This section describes the planned functionality.

When active, Traceable will log QR code scan events to provide insight into how your DPPs are being accessed. For each scan:

  • Timestamp — date and time of the scan
  • Country — the approximate country of origin based on IP geolocation (not always precise, particularly for VPN traffic)
  • Device type — whether the scan originated from a mobile device or desktop browser
  • Referrer — where the user came from if they accessed the DPP via a URL rather than a QR scan

Scan analytics will be collected anonymously. No personally identifiable information about the scanning user will be recorded.

QR Codes for Unpublished Products​

If a published product is subsequently unpublished, the QR code does not stop functioning as a scannable image — the QR URL remains active. However, instead of displaying the DPP, scanning the code shows a removed notice:

"This Digital Product Passport has been removed from public access. For enquiries about this product, please contact [operator contact email from company profile]."

This ensures that anyone who scans an existing label knows the DPP has been taken down and who to contact, rather than receiving a generic 404 error.

If the product is republished, the QR code automatically begins resolving to the new published DPP. No changes to existing labels are required.

QR Code Permanence​

Once generated, a QR code is permanent for the lifetime of the product record. Even if you update the product details, the QR code and its URL remain the same. The URL always resolves to the most current published version of the DPP.

If you need to link a new QR code to a product — for example, if a printed QR code was damaged or a new batch of packaging requires different dimensions — you do not need to create a new product. Simply download the existing QR code in the required format and dimensions.
