Reading RFID Cards at Yards Away
This article talks about a not-a-passport ID card that U.S. citizens could use to go back and forth between the U.S. and Canada or Mexico. Pretty basic stuff, but this paragraph jumped out:
Officials said the card would be about the size of a credit card, carry a picture of the holder and cost about $50, about half the price of a passport. It will be equipped with radio frequency identification, allowing it to be read from several yards away at border crossings.
“Several yards away”? What about inches?
