Communication at the airport
http://transgenderequality.wordpress.com/2010/11/23/communication-at-the-airport/While many Americans have general privacy concerns about new airport security procedures, there are many groups of travelers whose concerns about privacy or insensitive treatment by TSA personnel are especially acute, including religious minorities, transgender people, and people with a variety of medical conditions, disabilities, or assistive devices.
One specific concern shared by many of these groups involves communicating with TSA officers about sensitive personal or medical matters in the often noisy, crowded, and rushed environment of security checkpoints. To give travelers an additional option for addressing these issues, TSA has developed a standardized notification card that anyone can use to discreetly inform officers about any disability, medical condition or medical device that could affect security screening.
