Google continues to send QR bar-coded window stickers to U.S. businesses who are already signed up in the local business center, and meet other requirements such as number of searches for directions and other information.
Once the business is registered, they can add coupons, images, videos, descriptions, links, hours and more. Customers with smart phones then scan the sticker (try the one above to get to Nina Hale, Inc), read or write reviews, view the coupons or mark it as a favorite place to visit later.
This is a great way for small businesses to interact with their customers, and is a smart way to bring more people into the Google advertising funnel.
At this point there is no way to request inclusion in this Google Beta, but you can join the action by getting your own QR (quick response) code here and put it on your blog, site, or email.
