Amazon.com and subsidiary-of-search A9.com (remember them from your toolbar?) today announced Flow Powered by Amazon. Even their own marketing people don’t want to keep calling it that, so.. Flow is an augmented reality app that scans and recognizes everything from books and DVDs to packaged electronics and toys – and then digs up product information about the items from Amazon’s catalog. Thinly disguised marketing, yes, but also pretty nifty and useful in practice. And it’s free.
