following you around with the Jaws theme song looping in your head? How about RFID-enabled shelves that peer into every decision you do (or don't) make while shopping for gifts, gadgets, or everyday necessities? Japanese outfits DNP, Tana-X, and SEARS (not to be confused with Sears), are developing an intelligent shelving system that tracks information on the amount of folks who pondered a purchase, how many tossed it in their carts, which items attracted little to no attention, and essentially anything else regarding the popularity (or lack thereof) of a stocked item. Information is also gathered on the kinds of products individuals purchase together (i.e. a PSP and a UMD in the same trip), and strategically located "POP" machines conveniently give detailed descriptions about scanned items to customers, while sneakily collecting data of its own for those oh-so-clever marketers behind the scenes. While we aren't sure which nations are targeted for primary testing in December, you should probably pack some RFID-zapping heat when perusing through the aisles this holiday season if this tin-hat-donner has you in a tizzy like it does us.
