Lines can be long at airport security. The Transportation Security Administration knows too. Documents obtained by Eyewitness News showed TSA tested a project to measure how long.
Sensors in the terminal found Bluetooth devices, honed in on the signals and tracked how long it took people to get through security.
An internal TSA document stated it worked by, “…detecting signals broadcast to the public by individual devices and calculating a wait time as the signal passes sensors positioned to cover the area in which passengers may wait in line.”
