List Builder scan mode explained
List Builder is a scan mode on the Qflow check-in app. When enabled, it creates attendee records from QR codes that contain full guest profile data -- not just a barcode number, but also the guest name, tags, and additional information.
This article covers the List Builder scan mode in the check-in app. For the Guest Allotment system, see the Team Member & Guest Allotment collection.
You can generate List Builder QR codes during the invite creation process. They are automatically included in your e-invites.
Using List Builder for in-venue session check-in
Open Settings on the check-in app and enable List builder codes.
Assign a session or scan point tag.
Return to the Scan page and begin scanning.
Each scan creates an attendee record that includes the session or scan point tag. Statistics for each tag are available on the web dashboard and the app's Stats tab.
Use cases
Attendees can present their QR code repeatedly at different in-venue access points:
Event-level check-in - Secure entry scanning.
Session or zone access - Filter by registration type or guest tag.
Open sessions - Track attendance without restricting entry.
Voucher redemption - Record voucher scans at specific points.
Lead capture - Track interest at specific product or exhibitor stations.
