Static vs Dynamic QR Codes
Understand the difference between static and dynamic QR codes, including privacy, editing, analytics, expiry and when each is appropriate.
What a static QR code contains
A static QR code stores its content directly in the pattern. There is no redirect, tracking layer, account dashboard or expiry date managed by the generator. The code works for as long as the content or destination exists.
This makes static codes predictable and private. The trade-off is that the content cannot be edited after the code is downloaded or printed. To change a destination, create a new code and replace the old one.
What dynamic QR codes add
Dynamic QR codes usually point to a redirect service. The service can change the destination, count scans and apply rules such as location or device. Those features require an account, a database and ongoing service availability.
Dynamic codes are useful for campaigns and editable destinations, but they introduce a dependency. If the service stops, the code may stop working or behave differently.
Choosing the right type
Use static codes for permanent information, contact details, Wi-Fi access, payment requests and simple links. They are free, private and do not expire by themselves.
Use dynamic codes only when you genuinely need editing or analytics, and understand the privacy and availability trade-offs. QRKit generates static codes only.
