Porsche uses phone-formatted bar codes to connect with customers

Porsche is harnessing the power of smartphones, using Microsoft Tag bar codes to provide dealership customers with unique information about the cars they're looking at. Buyers can scan the square stickers with a properly equipped phone, and the application will take them to dedicated microsites where they can see stats, videos and pictures of the car, along with audio clips of a flat-six engine revving up.
