Static codes embed the data
A code can hold a URL or a complete payload like WiFi credentials. The image keeps encoding the same value. Changing the value requires a new image.
Dynamic workflows add a redirect
The code embeds a stable redirect URL. The owner can update that URL’s destination without editing the image. The redirect needs a reliable host and continued maintenance.
Choose for the project
Use static text or WiFi for simple offline content. For long-lived printed signage, consider a permanent domain path that your team can update.
