Keitai Watch reports that as part of a renewal of their site, Amazon Japan has introduced a flattering new feature called "Amazon Scan Search." After users download an application to their cell phone free of charge, they can scan barcodes of ordinary products, which in turn enables them to search the cell phone version of Amazon.co.jp for the respective product. Once they get a result on their search, they can then choose to purchase the item right from their phone. Obviously, there's quite a bit of overhead associated with this — like needing a phone with a camera, needing to use i-Mode, and needing to, you know, be in Japan — but I'm willing to ignore that for now.
Amazon Japan of course intends the service be used for on-the-spot price comparisons, as well as "finding out what sort of products are sold should you want something that your friend has." I'd say I await Amazon in America to introduce a similar service, but I will probably be waiting for all eternity.
