A TSA badge is about as useful as a nurse's hospital ID badge when they are on the ramp. The game they played in BGR was to have the TSA badge displayed and their SIDA badge in their pocket so from more than 10 feet away it looked they were all kosher. Bastards, I got a week off without pay for not realizing that one. The worst part was sitting through that fricking SIDA class again. I love how if a ramper fails to wear a badge they get in trouble, and if a ramper fails to not see a badge they get in trouble too. The TSA didn't like me much after that. Whenever I fly out of BGR they still pull me aside for 'random' checks every time. Random my ass.
The TSA badge is light blue with the emblem on the top their pic in the middle and their name underneath, but thats not what you are looking for. Whoops thats SSI and i'm gonna be on some naughty wire tap list for that.
