We compared entry-line speed across manual list-checking and QR-based scanning. The difference showed up fastest at events over 200 attendees.
Every organizer eventually asks the same question: is QR check-in worth setting up, or is a printed list and a pen good enough? The honest answer depends almost entirely on your attendee count.
For events under roughly 100 attendees, a manual list works fine — your team can visually confirm names quickly, and the overhead of setting up scanning hardware may not be worth it.
Past that threshold, the math changes fast. Manual name-matching slows down non-linearly as lines form, because staff have to scroll through longer lists per person. QR scanning keeps per-person entry time roughly constant regardless of total attendee count, since each scan is a direct lookup rather than a search.
There's a second, less obvious benefit: QR check-in gives you a live, accurate attendance count as the event happens, instead of a rough headcount estimated after the fact — which matters a lot when you're reporting numbers back to sponsors or co-organizers.
If you're running anything larger than a small meetup, QR-based entry pays for itself within the first hour of your door opening.
