Quadcom badge
A Starfleet quadcom badge
The Quadcom badge was the early 33rd century version of the combadge and 32nd century tricom badge.
Ostensibly, it had the same features as the Tricom; a combination combadge, holoPADD, tricorder, computer, portable transporter, and others beyond the previous tricom. It was designed to be worn on a Starfleet uniform's left breast. (DIS: "Life, Itself")
The name of the new combadge was not revealed in dialog but via its sale listing on Fansets. [1]
