I’m thinking any sort of card reader will have that information. I bet those kids have a library card with all that info on it. So the school has their name, address and stuff. So just put in how much money they have on account and subtract it. They don’t need personal history. I’m thinking that there’s too much hype about ID stuff. You have it in just about everything. So you stop one thing, but there’s so much more about you on all sorts of cards. I think the parents are over reacting.
It is not about stopping just one thing. You're right, there is far too much information out there - on almost everyone. I think everyone needs to be aware of who has that information and how it is protected. Just because your library requests the print or scan doesn't mean that they are protecting it. I write code as a hobby and am a white hat hacker - trust me, accessing data is frighteningly easy on far too many networks.
As more and more locations begin to collect this information, the risk grows exponentially. It is not acceptable just because it is becoming commonplace.
