People scan when the code is easy to notice, the value is clear and the experience feels trustworthy. These twelve practices improve both scan reliability and the likelihood that a visitor completes the next action.
1. State the benefit
Use a short call to action that explains what the scanner receives. “View the menu” is stronger than “Scan here.”
2. Maintain strong contrast
Keep the code visibly darker than its background. Brand colours can work well, but avoid combinations that make the modules difficult for a camera to distinguish.
3. Protect the quiet zone
Leave an uncluttered margin around all four sides. Text, borders and imagery placed too close to the code can interfere with detection.
4. Print at an appropriate size
The required size increases with scanning distance and data density. Test the final artwork at the real viewing distance rather than relying on an on-screen preview.
5. Place it within comfortable reach
Avoid folds, curved surfaces, glare and locations where someone would need to block traffic or hold a phone at an awkward angle.
6. Use a dynamic destination
Dynamic codes let you correct links and update campaigns without replacing printed material. They also provide the scan information needed to improve performance.
7. Send visitors to a focused mobile page
Do not make people search your homepage for the promised content. Use a fast destination with one obvious next action.
8. Keep forms short
Ask only for information you truly need. Long forms increase abandonment, especially when someone is standing in a store or at an event.
9. Build trust around the code
Use your logo, brand style and a clear description of the destination. A recognisable domain also reassures cautious users.
10. Test across devices
Scan with several iPhone and Android models, under bright and dim lighting, before publishing. Always test the final printed or displayed version.
11. Measure placements separately
Use a unique code for each channel or location. This reveals whether a window sign, table card, package or flyer creates the strongest response.
12. Keep the promise current
Review live destinations regularly. Replace expired offers, maintain accurate information and never leave a permanent physical code pointing to an abandoned page.
Pre-launch checklist
- The benefit is clear before scanning.
- The code works at the intended distance.
- The destination loads quickly on mobile.
- Campaign tracking is configured.
- The experience has been tested by someone outside the project.
