Once your QR code is created, you might also wonder: is this QR code I found somewhere actually safe? That's exactly what the DoItQR Diagnostic tool is for.
It analyzes the content of a QR code — via image or link — and evaluates the risks:
- Reputation of the destination domain
- Presence of suspicious redirects or opaque shortened URLs
- Characteristic signals of phishing or malware
- Consistency between the displayed content and the actual destination
In 2026, 89% of smartphone users scan QR codes every month, yet many don't know that some codes can lead to fraudulent sites. DoItQR Diagnostic is your digital shield. — DoItQR, 2026 — basé sur FTC Consumer Survey 2025

- Strong contrast is mandatory. Always use a dark foreground on a light background. The minimum recommended contrast ratio is 3:1. Never invert colors — a light QR code on a dark background scans poorly.
- Quiet zone. Maintain at least 4 modules of white margin around the code on all sides. This border helps the scanner quickly identify where the code starts and ends.
- Size adapted to distance. Minimum 2 cm × 2 cm for reading at 20 cm. Add 1 cm per additional meter of distance for public displays.
- Short content = simpler code. The shorter the URL, the simpler and easier to scan the QR code. Use a URL shortener if necessary before generating the code.
- Test before distributing. Always print a test version at real size before mass printing. Most scanning errors are caught at this stage.
❌ The most common mistakes
- Using a textured background or image under the QR code
- Printing at low resolution (always use SVG or high-def PNG)
- Not testing on multiple devices before publishing
- Forgetting to add a call to action below the code ("Scan to…")
- Placing the QR code in a poorly lit or hard-to-reach location
