We know who you are, consumer

things of the past > privacy
Minority Report-like developments paving the way to a market dystopia:

"Once you buy your RFID-tagged jeans at The Gap with RFID-tagged money, walk out of the store wearing RFID-tagged shoes, and get into your car with its RFID-tagged tires, you could be tracked anywhere you travel. Bar codes are usually scanned at the store, but not after purchase. But RFID transponders are, in many cases, forever part of the product, and designed to respond when they receive a signal. Imagine everything you own is 'numbered, identified, catalogued, and tracked.' Anonymity and privacy? Gone in a hailstorm of invisible communication, betrayed by your very property."
