Yes. Every lead is attributed to the rep who scanned it.
Ownership follows through to your CRM
The rep who captures a lead becomes the owner on the CRM record, so the person who had the conversation is the person the follow-up sits with.
Visibility during and after the show
Admins can see activity by rep rather than waiting for a combined export at the end. That means you can see how the booth is performing while the show is still running, and review it properly afterwards.
Why this matters at a busy booth
With several reps working a stand, a single undifferentiated list of leads makes follow-up ambiguous and makes it impossible to tell who generated what.
