INFOLUST is the next thing on the net and in real life! Or so I'm told.... It's all about printing codes on everything you can lay your hand on. This image is an example from Semacode. Semacode works by embedding a URL (web address) into a sort of two-dimensional barcode which looks like a dense crossword puzzle (pictured) — called the tag. The SDK software contains the capability to detect and decode the tag very rapidly with the camera on your phone. It extracts the URL and sends you to that address using the phone's built-in browser. I think it's a pretty good idea!

They are however not the only company involved in exploiting this undiscovered country. Let's read some more:

'While they're online, consumers rely on Google to bring them instant answers. But even though, as shown above, the Googles and Yahoos are working hard to enable consumers to get answers on the go, one zone of unresponsiveness remains: real world objects.
This is where consumers’ 24/7 curiosity and heightened expectations clash with the harsh reality of dumb buildings, products, shop windows, billboards and so on. Most of these objects are incapable of communicating the how, who, when, why and what that INFOLUST consumers have come to rely on in an online world.

No wonder that a slew of innovative ‘ask and know’ ventures are jumping into this virgin INFOLUST market with both feet. Inspired by two-dimensional barcodes, they’re developing versatile ‘shotcodes’, ‘SMS codes’, ‘QR codes’ and ‘UPCODES’. These codes are designed to be attached, stuck, glued, or printed on objects, making those products smarter, adding relevant information or linking the viewer directly to a pertinent web page. Needless to say, this enables an additional INFOLUST eco-system that benefits curious minds as they roam the real world.' source: www.trendwatching.com
