Semacode’s application which encodes a URL is a system for ubiquitous computing.
“Pragmatically speaking, with Semacode SDK you can create visual tags for objects and contexts, and read them using a mobile camera phone. Our software running on your phone will then deliver you to the appropriate mobile content.
Semacode works by embedding a URL into a sort of two-dimensional barcode which looks like a dense crossword puzzle 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."
Semacode is one of easiest way to access a website with camera phone. People can use semacode in their business card or t-shirts for social network and advertising myself.
