I've had problems getting one. Taken a couple attempts at it when the drivers license renews. Last attempt, it seems those adopted need both the biological as well as the legal birth certificate. I've sorted my passport, so do have a passport card now - but I don't always travel with it. (One of the gotchas with GA flying, some days you end up taking a commercial flight home) Guess that changes. Previously, they would just wave you through and 'randomly' select you for fabric/skin swabs.
