Not to be confused with digital badge.
An electronic badge (or electronic conference badge) is a gadget that is a replacement for a traditional paper-based badge or pass issued at public events.[1] It is mainly handed out at computer (security) conferences and hacker events.[2] Their main feature is to display the name of the attendee, but due to their electronic nature they can include a variety of software. The badges were originally a tradition at DEF CON, but spread across different events.[3]
