Not all QR codes are created equal. Before you print 1,000 flyers, you need to understand the critical difference between Static and Dynamic codes. One lasts forever; the other might hold your data hostage.
What is a Static QR Code?
A Static QR code encodes the data directly into the pattern. If you create a code for "https://utilitykit.xyz", that URL is hardcoded into the black and white squares.
- Pros: It never expires. It works offline (for text/WiFi). It is 100% free. You own it.
- Cons: You cannot change the URL later. If you print it and then change your website link, you have to reprint the code.
UtilityKit generates Static QR codes. This ensures your privacy and means your codes will work forever without you paying us a subscription.
What is a Dynamic QR Code?
A Dynamic QR code encodes a short redirect URL (e.g., "qr.service.com/123"), which then redirects the user to your actual destination.
- Pros: You can change the destination URL anytime without reprinting. You can track scan analytics (location, time, device).
- Cons: It relies on the service provider's server. If they go out of business or you stop paying their subscription fee, the link breaks and your printed codes become useless.
Which Should You Choose?
For permanent uses like WiFi credentials, VCards, or deep links to stable websites, Static is usually better because it is free and safer.
For marketing campaigns where you need to track ROI or might change the landing page next week, Dynamic is necessary, but be prepared to pay a monthly fee to a provider.
