Where can I see how many tickets have been scanned?

To see how many tickets have been scanned, log in to your Billetto account and find your event in "Calendar" at the top-left panel. Click 'Manage' next to the relevant event. 

You will now be on the event overview page - scroll down to the subheading: Scanned Tickets

You will see a graph displaying the totals and timings of your scanned tickets.
