BusinessWeek - Retailing, the High-Tech Way:
"'DRAMATIC SHIFT.' While sensors and video cameras are just starting to make their way into some banks and supermarkets, retailers have been collecting data on customers for years, capturing their purchase decisions from loyalty-card programs and credit cards. Now retailers are starting to use all that data like never before to help with everything from scouting new store locations, to analyzing customer whims, to adjusting the temperature in the store so that it really is a cool place to shop (see table below)."
