Communicator
A communicator (or personal receiver or combadge), is a handheld communication devices used by many species for person-to-person, person-to-ship, and inter-ship communications. Communicators usually transmitted on subspace frequencies.
By the 24th century, these communication devices were integrated into the standard uniform badges and became known as combadges. Users no longer had to speak directly into the communicator, but rather could activate and deactivate them with the touch of a finger. The combadge came into general use by 2344. Late-24th century communicators were composed of a crystalline composite of silicon, beryllium, carbon-seventy, and gold.
The combadges were also designed to self-activate after their casing was destroyed to aid in the rescue of victims.
When accessing a computer, the communicator of the person at the terminal will log in the user information, thereby making it possible to trace back who accessed the computer.
In some cases, communicators served purposes beyond basic communication. For example, communicators were often used to allow transporter locks for beaming, thus acting as homing transponders. When used in tandem, two communicators could produce a sonic disruption by using sound beams to create a sympathetic vibration in an unstable object, such as a cliff face.
