🔄 Static vs. Dynamic QR Codes
Static QR Codes
Static QR codes contain fixed data that cannot be changed after generation. They're ideal for permanent information like contact details, WiFi passwords, or stable website URLs.
Advantages:
- No ongoing costs or subscriptions
- Work indefinitely without external dependencies
- Faster scanning due to direct data encoding
- Complete privacy - no tracking possible
Dynamic QR Codes
Dynamic QR codes redirect to a short URL that can be updated to point to different destinations. They offer flexibility and analytics but require ongoing service.
Advantages:
- Updateable content without reprinting
- Detailed analytics and tracking
- A/B testing capabilities
- Campaign management features
💡 Choosing Between Static and Dynamic
Use static QR codes for permanent information like contact details, WiFi passwords, or stable websites. Choose dynamic QR codes for marketing campaigns, temporary promotions, or when you need detailed analytics.
