Bad implementations do not "security theater" make. When I did some work for a large coffee company, they had turnstiles at their building entrances, and I don't remember any lines in the morning. The scan/auth/enter process went about as fast as if there was no turnstile.

I remember when I started at Microsoft decades ago that there were still "old-timers" who were pissy about having to use card keys to enter the building. With that attitude, man, did that ever explain Microsoft application and OS security in the early 2000s.
