Hi Sofia,
If you are talking about the QR code, you can download Cvent's OnArrival app to scan them for attendee check-in! I haven't used it yet - my events have either been a full OnArrival Premium kiosk check-in, or we've done OnArrival Basic just checking them in by name - but I'm hoping to use it at an upcoming event.
