Well it appears the Bush administration decided to outsource the manufacture of your RFID passport to a company in Thailand that has, in the past, been vulnerable to Chinese espionage. So the bad idea of having RFID chips in our American passports just got worse.
RFID chips can be found in the new US passport and other e-passports, certain credit cards, some employee and student ID's and various smart cards around the world.
More and more credit card companies and banks are issuing smart-cards with RFID chips. The new US passport, also called an e-passport, can be scanned from a distance. Your mass transit pass, student ID, or employee tag may be able to track you. Meanwhile, people have demonstrated that data stored on some of these devices can be read from afar. By putting your passport or smart card into an RFID blocking sleeve like the RFID shield, you greatly reduce the chance of someone reading your data from a distance.
The REAL ID act threatens to erode additional freedoms in the United States, whether the cards come with an RFID chip or not. Stop the national ID card law!
