Flight personnel often go through KCM (known crew member) and then show their ID at the gate if they want/need to pick up a paper boarding pass. At this point in time, they could certainly take off their ID, however, some leave them on, perhaps for fear of losing them in their bag when they may need it or want to show it. If you look at flight attendants who are working a flight, occasionally you'll see a DL FA with their ID around their neck tucked into their shirt/jacket. It isn't a requirement, but they want it handy just in case.
