A London bus shelter ad uses facial recognition software with an HD camera to determine whether a man or woman is standing in front of the screen. “Passers-by can opt in to view an ad and find out more about Plan's work, but men are denied the choice to view the full 40 second ad in order to highlight the fact that women and girls across the world are denied choices and opportunities on a daily basis due to poverty and discrimination.”
See the ad for women here - even if you’re a man. (If you click on the plus button, it moves the ad in increments - I could not get it to flow.)
