The British maker of Kit Kat chocolate bars says hidden tracking devices in candy bar wrappers could bring lucky winners prizes of thousands of pounds. Candy maker Nestle says its \"We Will Find You\" competition will involve global positioning system chips placed in six chocolate bar wrappers. Once one of the lucky bars is opened the GPS chip will be activated, sending a signal to Nestle, which says the winner will be located within 24 hours by a helicopter for hand delivery of a briefcase containing $16,000 in cash. The embedded chips will be placed in wrappers of KitKat 4 Finger, KitKat Chunky, Aero Peppermint Medium and Yorkie Milk chocolate bars, the company said. A promotional video from Nestle says it will \"scramble a crack team of highly trained individuals\" to find the winner of the jackpot..
