Last week, Business Week ran a very interesting article on new technologies being implemented by retailers to curtail shoplifting and other species of fraud. From smart video systems that can detect unusual patterns supposedly indicative of shoplifting to RFID-enabled shopping carts that lock down the wheels in a "push out" scam, the technology is rather impressive and potentially intrusive. Much of it is being implemented covertly, so they don't tip off the miscreants and out of fear of a privacy backlash. See: Attention, Shoplifters. Via Privacy Digest.
