Will airports screen for body signals?

One is a thermal imaging device that measures the temperature of a face. A screener would look for temperature changes — a possible stress response — as a person is asked questions.

Another device, an eye tracker, follows a person’s gaze, checks the amount of blinking and measures pupil dilation.

This is real Running Man type stuff. Mega-blinkers like Nancy Pelosi might find air travel difficult in the near future.
