Android Scan, one of the winners from the Google Android Developer Challenge, uses cell phone cameras and barcode recognition to tap into Amazon’s review database. From Silicon Valley Insider:
Scan barcodes on any book or CD when you’re in a store and your phone will pull up Amazon reviews and check local library listings to see if the book is in stock.
Why it’s cool: Google’s been pushing mobile barcode scanning, so they might dig this app, too. We assume the developers have included their Amazon referral code in the app so they get a 5%+ commission on any purchases you make, too.
