The location-based craze is moving indoors--fast.
A startup called Wifarer today announced that Boston's Prudential Center is now fully outfitted with indoor positioning software so that the many stores within the complex can pinpoint your location within 4 to 5 feet.
But don't freak out.
Unlike a startup called Euclid, which tracks your every step so long as your carrying a Wi-Fi-enabled smartphone, Wifarer only works after you've downloaded the app. No app, you're invisible, so the choice really is yours.
