My wife is reading the book “Spy Chips” by Albrecht & McIntyre.
It’s good. She keeps reading parts of it to me, and how all kinds of things can be tracked for marketing or “other” purposes.
It’s really creepy how much could be told by having a .25 mm chip in your shoe be read at many different locations, or an RFID tag on your vehicle showing that you went from an entrance to a highway, to an exit within a certain amount of time, which could get you a ticket for at least the average speed you must have driven to get there.
I figured it might make for some good conversation.
On a side note, I found a site where a guy makes a wallet that includes aluminum foil to block the RFID chips that are built into ID’s such as your driver’s license, Passport (US and Canada), and many credit cards.
Oh yea, and he makes his wallet out of duct tape too (which is pretty cool in and of it’s self).
