The Fundamental Distinction
When generating a QR code, you must decide between two architectural approaches: **Static** and **Dynamic**. Choosing the wrong type before sending thousands of flyers to a commercial print shop can lead to broken links or expensive re-printing.
What is a Static QR Code?
In a **Static QR Code**, the destination data (whether a website URL, Wi-Fi password, or vCard contact) is encoded directly into the black-and-white pixel matrix of the code.
What is a Dynamic QR Code?
In a **Dynamic QR Code**, the code encodes a short redirect link (such as `qrnaly.com/q/your-slug`) that routes visitors to your final destination URL on our secure server.
Summary Comparison Table
| Feature | Static QR Code | Dynamic QR Code |
|---|---|---|
| **Data Location** | Directly in QR pattern | Stored on server via short URL |
| **Can Edit Destination?** | ❌ No | ✅ Yes (anytime) |
| **Scan Tracking?** | ❌ No | ✅ Yes (real-time analytics) |
| **Requires Internet to Decode?** | ❌ Works offline | ⚠️ Requires internet to redirect |
| **Best For** | Wi-Fi, vCards, permanent URLs | Menus, billboards, packaging, campaigns |
Which One Should You Choose?
Use **Static QR Codes** for personal Wi-Fi access, permanent portfolio links, and digital business cards (vCards). Use **Dynamic QR Codes** for physical marketing campaigns, billboard advertisements, product packaging, and restaurant menus where content may change over time.
