"Radio frequency identification has been heralded as a breakthrough in tracking technology, and denounced as the next Big Brother surveillance tool. RFID sounds futuristic: A transmitter smaller than a dime embedded in everything from a T-shirt to human skin, communicating data over a short distance to a reading device. The technology has been around for decades -- the British used it to identify aircraft as friend or foe during World War II, and factory warehouses have used it more recently to make shipping more efficient. So why is it getting so much attention now? The short answer is that RFID has moved into more common corners of society."
