i want to create a form to send out via marketing email, and in that form have a a CTA to say yes i want to registry for such event. i know i can follow data from the form submission, but ideally i want to create a guest list - and have someway to generate a QR code to send back to the person who registers on the form or from the CTA button, is this possible?
that way when a guest arrives at an event, the qr code can be scanned and then post-event, we can follow up? does such a thing exist? TIA
