Fingerprint ID accounts are being introduced here in Oregon, right now. A couple of retail grocery stores, Safeway is one I think, are introducing private, member based systems that automatically charge your account with a simple fingerprint scan. Although no different in principle that credit card use, or a private card account, this is getting a bit big brotherish [sic], as expected. For now this is all private information, but soon it may be possible, for example, for your employer to track your purchases. One example given: Bob buys two six packs of beer at the store. Analysis of Bob's purchasing history indicates that Bob may have a drinking problem. Contact Bob's employer and doctor, and communicate the potential for a problem. I also wonder about the logic of behavior control and where that may lead in all of this. For example, taking things to the next logical step, will we begin to regulate the sugar, fat, or salt intake of potential or known food offenders. After all, like cigarettes, consumption of low quality foods accounts for many health problems and costs to the public - obesity, heart attacks, diabetes, high blood pressure, high cholesterol, etc. The logic is no different than that used to justify taxes on smoking, or the seat belt or helmet laws. Also, if citizen X buys a snow board, should he be assigned as high risk and penalized somehow? He is much more likely to cost the system money than someone less daring. A unified database could, hence probably will allow various institutions to monitor personal behavior through purchases and other trackable activities. Computing power makes the data management and interpretation possible.
