Ricoh is out with new apps for a technology called Clickable Paper. In a nutshell, it does away with the dreaded QR code by embedding hotspots directly into printed materials that are recognizable by an app.
Each hotspot can point to multiple links rather than just one as it is with QR codes. And since there is no ugly QR code gumming up the works, designers will love it. Of course, people will need some sort of indication that these hotspots actually exist on the paper in the first place.
