One code on the door, everything behind it

Programme, floor plan, speaker list and the feedback form — behind a single code that changes as the day goes on.

A destination that moves with the event

Before the doors open it points at the programme. Halfway through the last session it points at the feedback form. Afterwards it points at the slides. Same printed code, same posters, three different jobs.

Signage that reports back

A different code per sign tells you which entrance people actually used and which rooms drew a crowd, by hour. The time report is the interesting one at an event: it is a picture of the day.

Collecting things from attendees

Forms are hosted here, and submissions land in your account rather than a third-party inbox. Put one behind a code on the badge, the table or the closing slide.
