What a QR submission is
A QR code is generated for a form at a site. Scanning it opens that form in the phone's web browser; the person answers and taps Submit. Because the code already knows the project, form and site, nothing has to be chosen and no login is asked for.
Use it for feedback boxes, notice boards, help desks or any place where the public should be able to report without staff present. Each code can be set to expire on a date or after a number of submissions. Zite renders the code as a ready-to-print poster: the QR itself, a short link (links.zite.io/qr/…) for people who cannot scan, and the project and site names.
