Description
The PDFer add-on generates PDF tickets for events registered in EventON, automatically attaching the file to the confirmation email sent to the participant after registration is completed. It works as a component of the EventON ecosystem, allowing organizers to deliver professional proof of registration with the registrant’s name, complete event details, identification code, and a custom logo ready for printing or direct presentation on the day of the event.
Key Features

Creates the document at the moment the participant completes registration for the event. - Direct email attachment

Lets you adjust colors, logo, header, and footer according to the organizer’s identity. - Dynamic event fields

Each registrant receives their own document to store, print, or present on a mobile phone. - Fast check-in at credentialing

Who Is It Recommended For?

- Producers of conferences, workshops, meetups, and in-person courses with entry control.
- Promoters of paid events who need to provide formal proof of registration along with the registration confirmation.
