If thieves knew that what they were stealing wouldn't work until purchased, would their motive be removed? Two technology companies think so, and they have created an RFID solution to DVD theft and possibly to the theft of many other consumer electronic products.
Because the solution would disable the DVD at the point of manufacturing, and enable it upon purchase, it might thwart both in-store theft and theft during shipping.
