The combadge was a combination of a badge and communicator designed to be worn on a uniform. In Starfleet, the combadge replaced standalone communicators in the early 24th century. Worn on the breast of the uniform - they were activated by tapping them once and deactivated by tapping them twice. Combadges were used for on-board ship communication with other Starfleet personnel. Also they could be used by the transporter as a way to lock on to Starfleet personnel. Too bad this is not a functional combadge - its only a collectible keychain - a must-have for Star Trek fans everywhere!.
