Dynamic QR code

A dynamic code doesn't carry your real link. It carries a short URL that runs through a redirect service, and that service decides where each scan lands. Because the printed pattern only ever points at the redirect, you can swap the destination as often as you like and the code on the wall never changes.

The redirect is also what makes scan analytics possible: every scan passes through a server that can log it. TangoQR makes every code dynamic, free or paid. It's the whole product, not an upsell. Print once, repoint forever.
