To promote its Favorite Places effort, Google sent out QR-code enabled decals to the most searched for and researched local businesses on Google.com and Google maps. The businesses are invited to place the decals in their windows, and passersby will then be able to snap the QR codes with their smartphones to gain access to reviews, coupons and more. They can also star the site in case they want to patronize it in the future.
The effort is part of Google's overall effort to provide users with the best local business finds, online and off. In the future Google will send out more decals to qualifying businesses.
