Then, you change clothes, come back the next day with the same shoes on but a different RFID-tagged pair of pants, shirt, underwear, etc., they can throw all of those items into their Ann A Thema bucket based upon your assoication with the shoes, which they associated with your gum yesterday.

Those are the transmitting and receiving antennas that "talk" to the RFID tags, and the distances you see in the stores pretty well defines the range of the tags they're sensing.

    The tags work by retransmitting energy that they receive. In simpler terms, I'm saying "the tags don't have batteries." They have an antenna that is energized by the transmitters at the gates. They modulate the signal with the data contents of the chip, and rebroadcast it (typically at double the frequency of the received signal.) Since the strength of the signal fades with the cube of the distance, in order to read from a greater distance you have to transmit exponentially more power to read it from further and further away. Don't forget to double the distance measurement, because your transmitter has to send enough RF energy to power the chip circuit, which has to turn that into enough power to make it all the way back to your reciever. And no matter how much power you pump into these little chips, they're not capable of retransmitting more than a few milliwatts, which means that as the distance increases your receiver needs a bigger and bigger antenna.

    The concern for privacy isn't that the guys with satellites are watching your every move from 90 miles up. They don't need to. They simply need to subpoena the store's RFID log to see who's been coming and going, and when. It's much cheaper.

    It seems to me that pre-emptive regulations generally do not acheive their goals. Often the regulations are influenced by the industry to be regulated. Generally, the regulations block a small firms from entering an industry and end up feeding the monopolies.

    Preemptive regulation generally has the effect of rewarding those companies on the inside track of the regulations (the politically connected) whild disenfranchising those who do not have the political connections to the regulators. As such it is best to put off regulation until the industry has matured a little.

    Preemptive regulations might be inspired by consumer fears. Lacking an actual history of abuses, the actual process of preemptive regulation tends to be controlled by the industry being regulated. As such, the regulation limits the number of players in a market and often comes up favorable to the companies being regulated.

    For example, you might recall several years ago when the House of Representatives considered a spam regulation bill. Without being passed into law, spammers slapped the House Bill number on their ads because the regulation was giving them legitimacy.

    Look at Internet porn. There was a great desire among legislators to find a way to block porn from kids. Without serious debates. The preemptive regulators listened to the porn dealers. The porn industry suggested that having a valid credit card number verified a person's age. Getting a credit card number is the first 90% of the battle to actually putting a charge on the credit card. While online news sources do not have a viable funding mechanism, the attempt to regulate an industry gave the porn industry the internet on a silver platter.
