You know, I never even realized until right now that my DL has a mag strip. This is a new thing for WI, I think. Pretty sure my recent MN didn't have one. I guess the more interesting thing would be, before wiping it out, to figure out a way to read it.
I'm sure you can buy card readers that will read it, but I'm equally sure you won't find anything sinister on it. From what I understand, all they put on the back is a machine-readable version of the text that's on the front. Nothing mysterious. Sooner or later the strips will be replaced with some kind of tamper-resistant smart chips, and then we will have a much harder time knowing what's on the chip. What's disgusting about Larry is that he wants to impose this on everyone but himself. When he checks into a hotel, do you think he whips out the Larry credit card and drivers license? No, of course not. He has an assistant who checks in for him. He is completely anonymous in this case. When he gets on a commercial plane, does he have to show id and have his bags searched and remove all metal objects? No, of course not because he doesn't fly on commercial planes. I'm sure that the actual number of times Larry has to show ID or use his personal credit card per year are pretty close to zero. Compare that to the average American, who will have to show Larry-ID(tm) every time he does any kind of financial transaction, travels anywhere, goes to a bar, goes to the gym, goes to a library, rents a movie, signs up with an ISP, or anything.
