Update the page. Same QR.
Content moves. The blog post you launched gets revised. The newsletter archive moves to a new platform. The event registration page becomes the event recap page becomes the next year's announcement. A static QR pointing at a single URL captures one moment in time — and goes stale as soon as the content evolves.
A dynamic QR code points to a redirect URL (qrth.is/r/abc), and you control where the redirect goes. As your content moves, you just update the destination — the printed QR keeps working through every URL change. Newsletters, evergreen blog posts, recurring events, ongoing product pages: all stay reachable from the same printed code.
