Where QR Codes Are Used in the Real World
- Restaurant menus — Contactless, hygienic, and always up to date. Update the URL the code points to without reprinting.
- Business cards — Encode your LinkedIn profile or portfolio URL for instant digital connection.
- Academic posters and presentations — Link directly to your full paper, dataset, or supplementary materials.
- Product packaging — Link to product manuals, warranty registration, or how-to videos.
- Marketing campaigns — Bridge print advertising to digital landing pages and track engagement via URL shortener analytics.
- Wi-Fi sharing — Encode Wi-Fi credentials so guests can connect without typing a long password.
QR Code Best Practices
- Always test your QR code on multiple devices before printing at scale.
- Ensure sufficient contrast — black codes on white backgrounds are most scannable. Avoid placing QR codes on busy or colourful backgrounds.
- For URLs, use HTTPS links — some QR scanners warn users about HTTP (insecure) links.
- Leave a quiet zone (white border) of at least 4 modules around the code for reliable scanning.
- For long-term use, consider shortening the URL with Flixfer's URL Shortener first — shorter URLs result in less dense QR codes that scan more reliably.
