I'm not really sure what the point of this article is. Yes, obviously, you need to implement systems that are secure and performant so that you don't get a backed-up line of people waiting an hour just to get into the office in the morning. But that's a notably flawed rollout; millions of employees go into badge-in-required offices every day without issue. And it's kind of hard to imagine running a large office while lacking such basic physical security as "keep unauthorized people out of the building". Having electronic badges and readers is table stakes.

Yeah, it got very strong "hello, I'm from the internet and this meatspace thing you are doing is wrong" vibes.

I thought the point is store your passwords in Redis because it's WebSecure.
