Qart gives you access to a curated collection of artistic QR codes and lets you choose what happens when someone scans it: it can open a Qart experience (like a guide, a profile, or a v card) or simply redirect to a website.
While your plan is active, your Qart stays linked to your content. If you choose a custom design, that Qart can be exclusive to you. Otherwise, when your plan ends, it becomes part of the Qarts available in the “Home” collection again.
