Abstract: A computer-implemented method for self-registration by an attendee for an event, wherein the attendee accesses via the internet a log-in screen for the event organizer and inputs personal information required for that event. The event organizer provides to the attendee via the internet registration and payment information, and the attendee registers and pays fees for the event. Following confirmation of receipt of payment and registration, the attendee generates a badge electronically. The event organizer generates a document containing the badge; the attendee prints the document, cuts the badge from it and takes the pre-printed badge to the event. The event organizer verifies the badge and mates it with an event-specific badge holder that coordinates with the badge to serve as a credential valid for use at the event.
