Over 100,000 business have been selected as "Favorite Places in Google." Over 9,000 cities and towns in all 50 U.S. states are included. The businesses are being sent decals they can place in their storefront windows. The decals include a barcode, known as a QR code, that can be scanned by smartphones, including iPhone, Android, and BlackBerry.
When the QR code is scanned, it will take the user directly to the business's Place Page on Google Maps. There you can get coupons, read reviews and star it for future reference.
To use it, you'll need an application on your phone that can scan QR codes.
