They kinda are. Recently some lawyers got banned from Madison Square Garden because MSG corporate bans lawyers involved in cases against them from their venues. They found a lawyers image somewhere and fed it into the "banned from this establishment" facial recognition group .

Nobody really knew about this till the lawyer showed up to a show there with a girl scout troop going to a Christmas Show and was denied entrance. If they can do it to a lawyer..

Facial recognition is probably a last resort given there are better signatures.
