The team has added a highly-requested in-person event feature that allows organizers to check-in attendees via QR codes. This functionality is optional and can be activated in Campaign Setup at any time.
If you are running an event or an in-person fundraiser, it’s easy to check in attendees or participants from your DoJiggy account. Marking people as checked in when they arrive can help you manage attendance and keep accurate reports.
