Amazon.com will join the iPhone frenzy on Wednesday with a new application available free for download through Apple’s App Store. The software is relatively straightforward, offering a way for iPhone or iPod Touch owners to browse through all the products offered by Amazon.com, as well as by third-party retailers like Target and Macy’s that make their products available online through Amazon. There is, however, one unusual and noteworthy aspect of the app called Amazon Remembers, which Amazon is calling “experimental.” The tool lets users take a photograph of any product they see in the real world. The photos are then uploaded to Amazon and turned over to the far-flung freelance workers in Amazon’s Mechanical Turk program, who will try to match them with products for sale on Amazon.com. The results will not be instantaneous (between 5 minutes and 24 hours, the company says), but the idea is to entice consumers to buy products from Amazon instead of its offline rivals.
