Static vs Dynamic
Permanent codes vs editable, trackable codes — explained simply.
This is the most important choice when creating a code. The difference is simple:
Static — free forever
The content is baked directly into the code. It never expires, has no scan limit, and works offline forever. Best for Wi-Fi, contact cards, fixed URLs and anything that will never change. Trade-off: if the content is wrong, you must reprint.
Dynamic — editable & trackable
The code points to a short link (qr.nxtgensec.org/r/xxxx) that you control. Change the destination anytime from your dashboard — the printed code keeps working. Every scan is recorded for analytics. You can also pause a dynamic code to stop it working temporarily.
Rule of thumb: use static for permanent things, dynamic for anything you might change or want to measure. The free plan includes 3 dynamic codes so you can try it.
