There are a couple of ways this can be done:
1. You can access (and print automatically generated guest lists, and use these to manually check names/email address/order IDs/ticket IDs - whichever you prefer - on the door.
To access the guest lists, you need to log into your Billetto account and find your event in "My events" at the top-left panel. From here, click 'Manage' next to the relevant event where you will be taken to the Overview page. In the list of options on the left, select 'Guestlist & Reports", where you will be offered a variety of formats.
2. You can scan tickets on the door, using our Billetto app.
If you would like others to be able to scan on your behalf, then you will need to give them your Billetto generated Organiser Key. This will allow them to use the app, under their own log-in details, but sync with your event (without gaining access to sensitive information).
