Like a self-checkout line at the grocery counter, these robots will save on labor, each one doing the work of five human ticket agents. Thales, the French company that makes the robots, says will share scans of passengers' faces with other computers around the airport. It then prints the passenger's face on the boarding pass, somehow in an encrypted form. Gate agents can then check the scan, confirming that the person the robot saw is in fact the person they are letting on the plane.
