BigBrother comes to Walmart
Wal-Mart will put Radio Frequency I.D. sensors on shelves stocked with RFID-tagged Gillette products, but they'd rather you didn't know about it, because, you might not like it, and then you might make noise and then they'd have a big PR mess on their hands.
You might even stop buying Gillette products or, say, refuse to shop at Wal-Mart.
These chips, researched at M.I.T.'s Auto-ID Center are about the size of a grain of sand. Chipsters say the technology will only be used to help retailers keep track of inventory - like bar codes. But privacy-loving consumers question the very concept of a device that sends out radio waves to "readers" that not only identify the article, but where and with whom it's going.
Wal-Mart is starting this at its Brockton, MA store which is in a low-income, minority area.
