The outcome of both are pretty similar. They have their differences when it comes to changes, updates, stats, track.
With Dynamic Qr Codes you can create a customized landing page for your QR Code that can be changed and updated whenever you want no matter if the QR Code is created or even if it went public.Dynamic Qr Codes also give you statistics of how many people scanned your QR Codes, from where and on what date.This QR Code type is most used by business owners (restaurants, gyms, clothing stores, etc.), artists, influencers, and non-developers users.
Static QR Codes on the other hand can't be changed or updated once created and went public.Also, static QR Codes do NOT give you statistics of how many people scanned your QR Codes, from where and on what date.This QR Code type is most used by developers and users who can create an url (landing page) for themselves.
