"Library officials said they wanted to tighten computer access because many people borrow library cards and pass codes from friends or family to log on"
So what? Who cares if someone borrows a card to use the computer? If they're so concerned, why not ask for picture ID?
But again, who cares? I guess I'm missing something.
It sounds like they're using the fingerprint scanner check during the online use, so kids don't swap ID logons after they've been let in by a human. I'm going to forward this post to someone who lives in Naperville and get her take on this.
