Am I the only one who finds this post weird because this is a solved problem? I've worked for 18 years at companies where everyone had to badge into every building. There have never been lines of people waiting to get in. Once I worked in a 12-story building. Of course, the badging wasn't in the elevators: the elevator lobbies on each floor had doors with badge readers.

The feel of the piece is that the entire effort was misguided, when the real story seems to be, "My company was somehow unable to implement something that every other company does easily."
