Members of the military might get a kick out of this. While flying out of MCI, I was wanded and my wallet beeped. So I took out my CAC card and showed the screener what a CAC card was. (It is your military I.D. card, and has a small foil chip implanted inside). The screener, ever vigilant, decided said I.D. card would have to be X-rayed. So I took my Air Force I.D. card, laid it in the grey tub, and sent it through the X-ray machine. The lady running the X-ray looked at the image, looked up at the screener, and said "What that heck am I supposed to be looking at here?" The screener told her, "it's his Air Force I.D. card". The lady sent the card out the tail end of the conveyer belt, looked at me, and said "I'm sorry!". By this time, I was doing all I could not to burst out laughing. Sometimes the situation becomes such a joke, you just gotta laugh!!

BTW, my CAC card still works, even the mag stripe ^
