AR goggles require a built-in camera. Presumably the glasses will be portable.
The hardware required for AR glasses to do what they are advertised to do (eg: translate street signs, overlay advertisements while you're trying to eat, etc) is sufficient to identify anyone walking by*.
Not hard to write software to display on the wearer's HUD, for example, random photos and social media posts of whoever enters their field of view.
*providing the other things in my comment are in place.
