Combadge

A Combadge is a small personnel communications device integrated into an insignia badge of organizations such as the United Federation of Planets Starfleet and the Bajoran Militia.
Combadges are used for communications from individuals to other persons, starships, planetary locations and anywhere else within the range of the device. They also function as a locator device for transporter beams and have integrated universal translators.
== History ==
Starfleet first began using combadges in the late 23rd century to the early 24th century. The combadge replaced the earlier communicator. Starfleet combadges are worn by officers, enlisted personnel, Starfleet Academy cadets, and other personnel attached to Starfleet. Starfleet combadges are worn on an individual's left breast.
Academy cadets were not allowed to use the combadges during off hours for communications without emergency contact authorization by a Starfleet officer.
By the mid 24th century Klingons had also replaced their communicators with combadges which were worn on their arms.
The Bajoran Militia also used combadges which functioned similarly to the Starfleet combadge; however, it was worn on an individual's right breast.
