What is a Static QR Code?
A static QR code encodes the data directly into the pattern itself. Once generated, the destination cannot be changed. This is ideal for vCards, WiFi passwords, or permanent URLs. Because the data is embedded, they require no ongoing subscription to maintain.
What is a Dynamic QR Code?
A dynamic QR code encodes a short URL that redirects to your actual destination. This allows you to change the destination URL later without reprinting the code. It also enables tracking (scans, location, device type). However, if the service provider goes out of business or you stop paying, the code breaks.
The Verdict
If you need permanent reliability and no recurring fees, use Static QR Codes (like the ones generated by QR Forge). If you are running an evolving marketing campaign and need analytics, dynamic codes are the way to go.
