In Hungary, Latvia, and Greece, travelers will be given an automated lie-detection test—by an animated AI border agent. The system, called iBorderCtrl, is part of a six-month pilot led by the Hungarian National Police at four different border crossing points.

"We're employing existing and proven technologies—as well as novel ones—to empower border agents to increase the accuracy and efficiency of border checks," project coordinator George Boultadakis of European Dynamics in Luxembourg told the European Commission. "iBorderCtrl's system will collect data that will move beyond biometrics and on to biomarkers of deceit."

The virtual border control agent will ask travelers questions after they've passed through the checkpoint. Questions include, "What's in your suitcase?" and "If you open the suitcase and show me what is inside, will it confirm that your answers were true?" according to New Scientist.
