Unsuspecting US travelers can now travel overseas never imagining that terrorists who might want to target people of certain nationalities need only purchase an RFID reader and read the transponders on the passports of the US travelers. The terrorists can have an area wired with bombs and simply detonate them when the RFID reader indicates a sufficient number of US travelers are milling about.
Presently, the RFID readers are being used to procure your credit or debit card information which is then “sold” to another party, usually someone not in the immediate geographic location. Then that person happily spends your money until you become aware of it and cancel the card, or until the account becomes overdrawn.
Your protection from this is to wrap your cards in tinfoil. Yup! It's not a tinfoil hat, but it's an approximation of a Faraday cage invented by Michael Faraday (not Daniel Faraday, although with all the time shifting in Lost, are we sure Daniel Faraday is not Michael Faraday?). So now I'm going to be the peculiar customer who must unwind the tinfoil from her driver's license and credit and debit cards when she shops. All the people in the line waiting patiently behind me will be overjoyed by this as I carefully unwrap then re-wrap my treasures. And I suppose the next time I travel I'll set off the metal detector with my tinfoil-wrapped passport. Ah! Life is so wonderful! Now, if I could only get my stolen money back from Alexey.
