The Starfleet badge of the late 32nd century, which combines a communicator, tricorder, holographic PADD and personal transporter in one device worn on the uniform.
The tricom badge takes its name from the three tools it merges with the familiar communicator. It is worked by taps and hand gestures: one opens a floating holographic display, another calls up tricorder readings, and a tap sets the transporter going. The badge also shows the wearer's rank.
It is introduced in the Discovery episode Die Trying, set in 3189, when the crew reach Federation Headquarters. Philippa Georgiou examines and breaks the badge worn by Kovich during her debriefing.
The crew of Discovery are issued with the new badges in place of their 23rd-century ones, and Scavengers shows them getting used to the controls, with Linus repeatedly beaming into the wrong room. The badges remain standard equipment for the rest of the series.
