A QR code on a political advertisement is the bridge between a physical ad and its legally required transparency notice. Under EU Regulation 2024/900, every political ad must provide the audience with a way to access the full transparency notice. For print materials — flyers, posters, newspaper ads, and direct mail — a QR code is the most practical solution.
Why QR Codes Matter for Political Advertising
Digital political ads can link directly to their transparency notice via a hyperlink embedded in the ad unit. Print advertising does not have that option. A newspaper ad or a campaign poster cannot contain a clickable link. The regulation requires an alternative mechanism, and QR codes have emerged as the standard approach.
When a citizen encounters a political ad on a billboard, in a newspaper, or on a flyer in their mailbox, they should be able to scan the QR code with their phone and immediately see: who paid for the ad, how much it cost, where and when it is being distributed, and who is responsible for the content. This is the transparency that the regulation was designed to deliver.
How QR Codes Link to the Public Register
Each transparency notice created on the Taurus platform receives a unique 17-digit public ID. This ID is encoded into the QR code, which resolves to a publicly accessible page displaying the full notice. The URL structure is permanent and stable — it will work for the entire 5-year retention period required by Art. 12 PAR.
The flow works like this:
- The sponsor creates a transparency notice on Taurus and publishes it.
- Taurus generates a QR code linked to the notice's public page.
- The sponsor or publisher places the QR code on the printed advertisement.
- A citizen scans the QR code with any smartphone camera.
- The citizen's browser opens the notice page showing all Art. 9 mandatory fields.
No app download is required. No registration is needed. The notice page is designed to load quickly on mobile devices and display the information clearly.
Print Guidelines for QR Code Placement
A QR code that cannot be scanned is worse than no QR code at all — it gives the appearance of compliance without delivering transparency. Follow these guidelines to ensure your QR codes work reliably.
Minimum Size
The QR code should be at least 2 cm x 2 cm (approximately 0.8 x 0.8 inches) for materials viewed at arm's length, such as flyers, leaflets, and newspaper ads. For posters and billboards viewed from a distance, scale up proportionally — a poster viewed from 3 metres should have a QR code of at least 6 cm x 6 cm.
Placement
Position the QR code in a consistent, predictable location. The bottom-right corner of the ad is the most common convention. Avoid placing the QR code over busy backgrounds, photographs, or complex graphics. If the ad has a white or light-coloured border or margin, place the QR code there.
Contrast
QR codes require high contrast to scan reliably. The standard is dark modules on a light background — black on white provides the best results. Avoid reversing the colours (white on black) or using low-contrast colour combinations. If your ad's colour scheme makes contrast difficult, place the QR code inside a white box with adequate padding.
Quiet Zone
Every QR code needs a clear margin around it — called the "quiet zone" — to be reliably detected by scanners. Maintain at least 4 modules' worth of clear space (approximately 2-3 mm for a standard-sized code) on all sides. Do not let text, borders, or graphic elements encroach on this space.
Resolution
For print production, generate the QR code as a vector file (SVG or PDF) rather than a raster image. This ensures the code remains sharp at any print size. Raster images (PNG, JPG) can become blurry when scaled, particularly for large-format printing.
Custom Branding Options
While the QR code itself must remain scannable, there is room for branding within the guidelines. The Taurus platform offers several customisation options:
- Colour — The QR code modules can use any dark colour, provided sufficient contrast with the background is maintained. A party's primary colour on a white background works well.
- Logo overlay — A small logo or icon can be placed in the centre of the QR code. QR codes have built-in error correction that allows up to 30% of the code to be obscured while remaining scannable. Taurus generates codes with high error correction to support this.
- Frame and label — A text label below the QR code (e.g., "Scan for transparency info") helps viewers understand its purpose. This is particularly useful during the early adoption period when citizens are still becoming familiar with the requirement.
How Readers Use QR Codes to Verify Ad Transparency
From the citizen's perspective, the QR code answers a simple question: "Who is behind this ad?" The process is deliberately frictionless:
- Point your phone camera at the QR code.
- Tap the notification that appears.
- Read the transparency notice on the page that opens.
The notice page shows the sponsor's identity, the financial details, the publication context, and — for digital ads — the targeting criteria. Citizens can use this information to assess the ad's credibility, report concerns to the competent authority, or simply satisfy their curiosity about who is trying to influence their views.
For journalists and researchers, the public notice pages provide a structured, machine-readable dataset of political advertising activity — a significant improvement over the fragmented and opaque landscape that existed before the regulation.
Generate Your First QR Code
Creating a transparency notice and downloading its QR code takes less than 10 minutes on the Taurus platform. If you are a candidate preparing campaign materials, build QR code generation into your production workflow from the start. Create the notice, download the code, and hand it to your designer alongside the ad creative. Compliance becomes part of the production process rather than an afterthought.
