10 Important Star Trek Details That Are Almost Never Mentioned

The Voyager episode Distant Origin showed us something very interesting about Starfleet's uniforms during the time period.

Two Voth scientists found one of Voyager's uniforms, along with the skeleton of a member of the crew, and used these findings to locate Voyager, in an effort to prove that the Voth and Humans shared a common ancestor and came from the same planet, Earth. Later in the episode we learn that this theory is actually true. The Voth were descended from dinosaurs who escaped the extinction event millions of years ago, who went on to evolve and become one of the most powerful empires in the galaxy.

What's interesting is that, when examining the uniform, the Voth scientist located what he called a "microscopic identification code." It's likely that this is a form of military dog tag for Starfleet officers, as a way to identify them in the event of their death. The I.D. shows the name of their ship, the U.S.S. Voyager, and some numbers that are likely a custom identification number assigned to everyone in the crew.

It's interesting that Starfleet still uses something similar to dog tags, but apparently on a microscopic level, probably to hide the information from enemies.
