Originally posted by JimJohnson The current US passport & passport card puts your personal information on an non-encrypted embedded RFID chip. I can't speak for other US States with enhanced driver's license, but if you have an enhanced Michigan DL, it is the same as having a US passport card - and has an non-encrypted embedded RFID chip. There is speculation that nefarious identity thieves can capture this data with portable RFID scanners. Standing in public airline ticketing areas or exits from baggage claim, car rental or hotel check-in desks are 'good' spots to capture this data. In short, use RFID shields with your official identification and minimize the time it sits outside these shields.
I changed to the enhanced Washington state driver's license when I drove big trucks, as the carrier I drove for sent me to Canada frequently, and it saved me time, and optimized the value of me as a driver for the carrier.
Although I no longer drive trucks, I keep the enhanced driver's license, as I travel to Canada for pleasure frequently, and it makes crossing the border quick and convenient. Now with the new airplane travel identification requirements changing, I am ready.
The DMV gives drivers a shielding sleeve to place the card in, and explains why. The sleeve is essentially a Faraday cage, blocking electromagnetic fields, thus preventing nefarious miscreants from taking that which is not theirs. I asked for extra sleeves, and then placed my credit cards in them to further protect my identity.
