Badges and ribbons Attendees are issued a convention badge, displaying each attendee's name, membership number and (if desired) "fannish" nickname. The customary practice is for all attendees at the same convention (occasionally excepting Guests of Honor) to wear badges of the same design, but each Worldcon's badge design is unique to that convention.
