Dynamic QR Codes vs. Static QR Codes

The key difference between dynamic and static QR codes is that dynamic QR codes can be edited and tracked, while static QR codes are fixed and unchangeable after creation.

1. Dynamic QR Codes

✅ Editable Content: The destination URL or information can be changed after the QR code is generated.
✅ Trackable Data: Provides scan analytics, including location, time, and device type.
✅ Short URL Redirection: Uses a short URL that redirects to the final destination.
✅ Password Protection & Expiry Dates: Can be secured or set to expire after a certain period.
✅ Best For: Marketing campaigns, event registrations, business links, and digital payments.

🔹 Example: A restaurant uses a dynamic QR code for its menu. If the menu changes, the restaurant can update the link without generating a new QR code.

2. Static QR Codes

❌ Fixed Content: The encoded data (e.g., URL, text, or contact info) cannot be changed after creation.
❌ No Tracking: Cannot collect scan analytics.
❌ Direct Storage: The data is embedded directly into the QR code (no redirection).
✅ Best For: Personal use, Wi-Fi credentials, printed materials, and one-time promotions.

🔹 Example: A business card with a static QR code containing a website URL. If the website URL changes, a new QR code must be generated.
