Everyone, please beware. Please follow the link below:
The gov't is aware of this because I just renewed my passport. I also decided to get a passport card, which I use as an ID instead of walking around with my passport book. Anyway, the card came with a protective aluminum sleeve. It had a padlock on the sleeve along with the blink symbol (((. It's supposed to protect my passport card from getting scanned.
This is truly scary.
