There are firms that embed electronic article surveillance (EAS) devices in products, such as shoes, power tools and so forth, in an attempt to reduce the theft of these items—the cost of which is then passed on to consumers.
Conventional EAS devices have a single bit that is either turned on or off at the checkout counter. Since there is no serial number, they can not be used to track individuals, even if they are not deactivated at checkout.
