Event day is Harp’s highest-concurrency moment: hundreds of hackers checking in, eating, and moving between workshops. Everything runs off each hacker’s personal QR code.

Scanning

  • QR scanning for check-in, meals, workshops, and any custom activity
  • Scan types are configurable per event, so you create one for each activity you want to track
  • Live scan statistics let organizers watch attendance as it happens

Meals

Meal groups split hackers into cohorts to load-balance food lines, with attendance visibility per group.

Schedule and announcements

  • Organizers create and update the schedule live during the event. Hackers see changes immediately in the portal, and the public site picks them up through the public API.
  • Scheduled announcements go out as notifications, written manually or generated from schedule items.

Hacker-facing resources

Schedules, notifications, FAQs, and the hacker pack are all served from the portal, so “where do I find X?” has one answer all weekend.
