Hiding Messages In Plain Sight

A technology that can “hide” information in plain sight on printed images has begun to see the first commercial applications. Japanese firm Fujitsu is pushing a technology that can encode data into a picture that is invisible to the human eye but can be decoded by a mobile phone with a camera. The company believes the technology will have spin off implications for the publishing industry.

This technology could have a variety of uses, but the main one that comes to mind for me is shopping catalogues. Imagine sitting back on the couch with a new flyer or catalogue and simply hovering over the item and verifying to place an order. The real goal seems to be being able to scan an article in order to download it into your cell phone, which works as well.
