# How do challenges stay fair?

One scan per booth per person, optional staff-verified scans, cooldowns and daily caps, and an audit trail for every point.

- A booth can only be counted once per attendee per challenge.
- Staff-verified scans: only exhibitor staff can scan attendees, so nobody can scan a photo of a booth QR from home.
- Cooldowns and caps stop rapid-fire scanning.
- Every point has an audit trail you can review before drawing winners, and you can disqualify entries.
