Looks like Willy Wonka has abandoned golden tickets in favor of GPS trackers. Nestle has randomly placed GPS devices in chocolate bars distributed in the UK to locate prize winners, including a grand prize of approximately $16,000.
With possible placements in Kit-Kat, Yorkie and Aero bars, the GPS tracking chips are programmed to activate when the packages are opened. Upon activation, the winner will be located and awarded his or her prize.
According to some reports, contest progress and results can be tracked via smart phone using NFC and QR codes.
