The App scans barcodes and retrieves prices. It can also find product information using photos snapped with your phone’s camera. You can do voice searches, too. With the new Google Shopper application you can scan a barcode or snap a photo of a retail item and the app will return a list of search results for that product. It will give you prices, ratings, photos and even descriptions. The results come from Google Product Search. Put a star on your favorites so that you can go back to them later.
It’s hard telling at this point whether the App will become available for any platform other than Google’s own. If not, I’d say that’s a pretty heavy marketing point. If you want the best shopping App available… you’ll have to buy an Android phone!
