A new lie detector, the GK-1, tested in Russia for airline security shows significant promise towards improving airline security. The GK-1, developed by Israeli firm Nemesysco, uses a minimally invasive two stage process to tell if a passenger is being untruthful.

The initial test takes between 30 to 75 seconds and can be performed as part of the standard security screening. Passengers simply put on a pair of headphones and look at a console to answer “yes” or “no” questions into a microphone. For those that fail the initial test, they are taken aside for a more extensive test.

At $10k to $30 per installation, the added speed and accuracy of the tests may be a good step towards improving airline safety and helping you get through the “line” that much faster.
