QR codes connect the physical and digital worlds. With a quick phone scan, customers can open a website, menu, payment page, review form, WhatsApp chat or app download. QR code generators let you create these codes in seconds, but good results depend on choosing the right type, designing for scanning and tracking performance.
Static vs Dynamic QR Codes
| — | — | — |
|---|---|---|
| Scan tracking | No (unless destination is tracked) | Yes |
| Cost | Usually free | Often subscription-based |
| Best for | Permanent links, Wi-Fi, contact cards | Campaigns, menus, changing offers |
Common QR Code Uses
- Restaurant menus and table ordering
- Review requests on receipts
- Product packaging with instructions or videos
- Event tickets and check-in
- Flyers and posters linking to landing pages
- WhatsApp chat links for customer support
- Wi-Fi access for guests
- Business cards with contact details
How to Create a QR Code
- Choose a reputable QR code generator
- Select the content type: URL, text, Wi-Fi, contact card, email or phone
- Enter the destination, ideally with UTM parameters for URLs
- Choose static or dynamic
- Customise colours and add a logo if supported
- Download in high resolution (SVG or PNG)
- Test with several phones before printing
Design Best Practices
| — | — |
|---|---|
| High contrast (dark code on light background) | Reliable scanning |
| Quiet zone (blank margin) | Helps scanners detect the code |
A common guideline is to make printed codes at least about 2 cm wide for close-range scanning, larger for posters viewed from a distance.
Add a Clear Call to Action
“Scan to view menu”, “Scan for 10% off” or “Scan to leave a review” encourages action. People are more likely to scan when they know the benefit.
Make Destination Pages Mobile-Friendly
QR codes are scanned on phones, so destination pages must load fast and work perfectly on mobile.
Tracking QR Code Performance
- Use dynamic codes for scan counts
- Add UTM parameters to destination URLs for analytics
- Use unique codes for different locations or campaigns
Security Considerations
Malicious QR codes can lead to phishing sites. Businesses should use trusted generators, place codes where they cannot easily be replaced with stickers and show the destination domain where possible. Users should check previews before opening links.
Common Mistakes
- Printing without testing
- Low contrast or tiny codes
- Linking to non-mobile pages
- Using dynamic codes from unreliable providers
- No call to action
Frequently Asked Questions
Do QR codes expire?
Static codes do not. Dynamic codes may stop working if the service subscription ends.
Can I add a logo to a QR code?
Yes, within limits; test scanning carefully.
Which file format is best for printing?
SVG or high-resolution PNG.
Can I track scans from static codes?
Indirectly, by adding UTM parameters to the destination URL.
Conclusion
QR codes are a simple bridge from offline to online. Choose static or dynamic codes based on your needs, design for reliable scanning, add clear calls to action, link to mobile-friendly pages and track results to measure impact.
