Conspiracy theorists and civil libertarians, fear not. The U.S. government will not use radio-frequency identification tags in the passports it issues to millions of Americans in the coming years.
Instead, the government will use "contactless chips."
Neat. So, in effect, it's the same as having a barcode or an ID number tattooed on your skin.
I have a couple of cats from the Humane Society, and they have tattoos in their ears instead of the RFID tags. Old tech, but still as effective as RFIDs, I suppose.
