I think Spiff is onto something here. I initially thought checking ID was harmless but it got me thinking about my irritations on personal info tracking. Go to Vegas and every casino wants you to sign up for their slot card. Why? To track your gambling habits; what you play, how often, the amount you play and a myriad of other variables.

Shop at Von's, Safeway, Albertson's and they all require you to sign up for their club card to get the discounts. Same deal, they track your spending habits. I have all the store club cards on my key ring but refuse to provide any personal data. It's nobody's business what I buy.

Technology is a wonderful thing but I'm sure these companies are selling and trading my personal information. I get uneasy when I receive a coupon printout with my grocery bill for an odd product I know I bought 3 weeks ago. I feel my privacy has been invaded or at least that of my pseudo identities of Mickey Mouse, SuperMan and Albert Einstein.
