Multiple stations are the obvious fix, but they only help if they work together rather than as separate, conflicting lists.

The double check-in risk

If stations do not share data, an attendee could be checked in at one door and then again at another, corrupting your arrival count. Related: Should a recurring event use reusable badges or freshly printed badges for each attendee arrival?

Worse, a badge could print twice, or a genuine attendee could be flagged as already arrived when they were not.

Staying in sync

Stations that share one live list mean a check-in at any door updates everywhere instantly, so no one is processed twice.

Attendees can approach whichever station is free, and the system treats the whole event as one coordinated check-in. Related: What are the benefits of printing event badges on site instead of pre printing them all in advance?

Scaling up smoothly

Because synced stations act as one, you can add another during a rush and it simply joins the same shared count.

That flexibility lets a big event scale its entrance to the crowd without ever losing the integrity of the arrival data. Related: How can organizers measure real event attendance instead of relying on registration numbers alone?
