Going through international security Friday I observed a security worker approach 3 people, had them press button on remote with green & red light, can't rember which light that flashed, worker took them to full scanner machine depending on colour. I thought I heard worker acknowledge when certain colour came up, they were for scanner. Just courious how colour was determined. The 3rd person had the other colour to other 2.
