Dynamic vs static QR codes: which to use and when
The difference is not visual quality — it is whether the destination lives inside the code or behind it.

Static: the URL is the code
A static QR encodes your destination URL directly in the pattern. Nothing sits between the scanner and your site. It works forever, needs no service, and cannot be tracked or changed. Longer URLs make denser, harder-to-scan codes.
Dynamic: the code points at a short link
A dynamic QR encodes a short link. The short link decides where to send people, which means you can change the destination, add targeting, and count scans. The pattern is simpler because the encoded URL is short, so it scans faster and prints smaller.
When static is the right answer
A Wi-Fi credential code, a vCard, a plain-text label, or a link on a disposable item where tracking is pointless. Also anywhere the code must keep working if every service you use today disappears.
When dynamic is the right answer
Anything printed in volume, anything with a campaign attached, anything where you might want different behaviour on iOS and Android, and anything where you need to know how it performed. Which is most marketing use.
The dependency you are accepting
A dynamic code stops working if the short domain stops resolving. Mitigate it by using a domain you own rather than a shared one, so you can repoint DNS at any provider — the printed codes keep working.
Error correction and logos
QR codes carry redundancy at four levels, L through H. Level H recovers from roughly thirty percent damage, which is what makes a centre logo possible. Higher correction means a denser code, so raise it only as far as your logo needs.
