Gradeschool and Highschool for me always required a Librarian to scan the book and then input your name. However, our Librarians knew every student by first and last name. College for me has a photo identification card that needs to be shown (with a magnetic stripe) and the books are linked to whoever is on the photo (you must match the photo).
I dislike the idea of using fingerprints. The government should NOT maintain this information. I can fully understand someones approach to this and why they want to use this, but as this gains popularity, it will become far easier for the governments to say, Hey, lets have a universal id system using fingerprints. Oh, you'll need the fingerprint to check out books, identify yourself for guns, for paying at the gas station, for getting on the city bus, etc. Yes it can create a significant convenience for the consumer, but now the government can track your every move, every purchase. Today's kids are going to be used to handing over every bit of personal information, our government certainly isn't going to protect our rights at this point, we need to protect them ourselves. (How often is the government supposed to be overthrown? Every 200 years?) I realize this article is about a school, but it all starts somewhere, right?
