A check-in kiosk is a self-service station, usually a tablet on a stand, where attendees check themselves in and collect a badge without staff assistance.
A staffed desk processes one attendee at a time per member of staff. A bank of kiosks lets several people check themselves in at once, which is why kiosks show up at events where arrivals bunch into the short window before a keynote. The math is simple: four kiosks and one roaming helper usually clear a queue faster than four people at a table.
The attendee either scans a QR code from their confirmation email or types their name to find their record. The kiosk confirms the match, marks them checked in and triggers a badge print. Good kiosk setups put the printer within arm's reach so the attendee collects their own badge without a handoff.
Three failure modes recur. Attendees who cannot find their confirmation email stall the line, so name lookup has to work as a fallback. Printers run out of stock mid-rush, so someone has to own reloading. And kiosks placed too close to the doors create a crowd in the entrance rather than a queue, which is a venue problem more than a software one.
Kiosk mode runs on an iPad and lets attendees scan their QR code to check themselves in and print a badge. The kiosk design and settings can be customized to match the event, and the same kiosk flow works for checking into individual sessions as well as into the event itself. See event check-in.
