The Microsoft Tag application gives people the ability to use a mobile phone's on-board camera to take a picture of a tag, and be directed to information in any form, such as text, vCard, URL, Online Photos, Online Video or contact details for the publisher.
Two-dimensional tags can be used to transform traditional marketing media (for example, print advertising, billboards, packaging and merchandising in stores or on LCDs) into gateways for accessing information online.
