When creating a QR code, you will encounter two types: static and dynamic. Choosing the right one depends on your needs, budget, and whether you need to change the content later. Here is a clear breakdown.
What is a static QR code?
A static QR code encodes data directly into the pattern of black and white modules. The information — whether it is a URL, WiFi credentials, or contact details — is baked into the code itself. Once created, it cannot be changed.
Key characteristics:
- Data is stored in the QR code itself, not on a server
- Works forever — no expiration, no server dependency
- Cannot be edited after creation
- Free to create (tools like Qrafy generate them at no cost)
- No tracking or analytics
What is a dynamic QR code?
A dynamic QR code does not contain the final destination directly. Instead, it encodes a short redirect URL (like a URL shortener). When scanned, the redirect sends the user to the actual destination — which can be changed at any time without reprinting the QR code.
Key characteristics:
- Data is stored on a server, not in the QR code
- Destination can be changed after printing
- Usually requires a paid subscription
- Includes scan analytics (number of scans, location, device type)
- Stops working if the service provider shuts down or you cancel your subscription
When to use static QR codes
- WiFi sharing (credentials do not change often)
- vCard contact cards (your phone number and email are stable)
- Personal use (sharing links with friends and family)
- Permanent signage (museum exhibits, memorial plaques)
- Any situation where the content will not change
When to use dynamic QR codes
- Marketing campaigns where you need to track scan metrics
- Situations where the destination URL might change
- A/B testing different landing pages
- Time-limited promotions where you want to redirect to a new offer later
The bottom line
For most personal and small business use cases, static QR codes are the better choice. They are free, permanent, and do not depend on any third-party service. Dynamic QR codes are worth the cost only when you need editability or analytics at scale.
