As far as I can see, the problem is with the Yelp organizers, not the security. I have attended quite a few tech talks by banking and finance firms in Chicago. Quite often they're also in some of the most high-profile buildings in the United States. On the listing of their events they always say in massive font at the bottom: IF YOU'RE NOT REGISTERED YOU WON'T GET IN.

There's nothing wrong with this policy. The problem is that the Yelp event organizers didn't sufficiently publicize this policy.

Edit: Apparently there was a guest list, everyone's name was on it, and hers was marked as not allowed for some unknown reason? This is not clear from the article, but I gather from the comments.

Re-read the story. The student was registered, but denied entry at the last moment for undisclosed reasons.

I did not read in the article that she was not registered?
