It looks like a TV station has done something similar, making an unofficial self-created "Identity Card: Personal Travel Identification", and then used it to pass a reporter thru a TSA screen.

I am amused. :)
ID cards are an utterly stupid idea. Lawmakers, security consultants, and ID fetishists who require ID cards, they are utter morons. If your job requires checking IDs, for your own sanity, you need to understand that it's ineffective makework that your boss makes you do, not because it's actually useful.
The only provable thing that you learn when someone shows you their ID, is that they own a photograph of themselves. Wow, that's so much useful information...
When someone gives you their frikken business card, you actually learn more immediately provably true information about them then if you look at their "official" ID.
