GPS tracking: We know where you are
Mall owners faced public outcry last year after announcing plans to discretely track shopper via their personal mobile devices. The purpose was to glean a precise view of customer foot traffic, which in turn could help retailers improve the layout of their businesses. The property owners postponed the project after being accused of violating privacy.
This technology is be cool in that it provides detailed, accurate, yet anonymous data on foot traffic, which could be used for designing better laid-out stores, stadiums, city streets, etc. Unfortunately, it turns creepy fast when you consider that a company could track you anonymously based on your device, collecting identifying information that could be sold or stolen.
