A convention ID badge system which provides a trade-show badging system for two-way data exchange. It uses a floppy disk as an ID badge and stores exhibitor's data on the ID badge. A user takes home an electronic record of the event, electronically stores all the brochures onto the diskette and computerizes a business card by using the IDisk. The new IDisk System replaces the old fashioned badge with a floppy disk loaded with information that attendees take home with them. The IDisk System has two components: the attendee Idisk badge and the exhibitor IDisk station. The badge identifies attendees by name visually and by electronic imprint, plus it provides room to retrieve selected data from the exhibitor's IDisk station.
