At the library where I work we’ve installed terminals where you can loan out your own items all by yourself. All you do is put the items on the bench in front of the terminal. Tap the ‘borrow’ button on the screen. Swipe your card down the reader on the side of the screen and the computer will sense all the items (via their RFID tags) and put them on your card for you.
Some borrowers find this rather magical, especially how it picks up all of the items at once. I told one man that I’d like to see the RFID tags keyed into a GPS system and when someone can’t find their book we could look it up on the computer and tell them it’s under their bed. Then, getting a little ahead of myself, I came up with an even better idea. If we had transporter technology we could program the books to automatically beam back to the library when they were due! I got a couple of very strange looks. One man showed me his Dr. Who DVD as if to say I was as crazy as the show, and another asked me if I was a Trekie.
