A press pass (alternately referre to as a journalist pass or a press card) grants some type of special privilege to journalists. Some cards have recognized legal status, others merely indicate that the bearer is a practicing journalist. The nature of the benefits is determined by the type of issuing agency, of which there are three major categories: news organizations, law-enforcement agencies, and event organizers (usually for a specific single affair like a corporate press conference). Each type of card grants different authorizations, thus it is often necessary or desirable for reporters to hold multiple press passes simultaneously.
