Semacode
A visual code that is a series of black and white squares that can be read like a barcode and interpreted as text. For example, in the picture to the right, a semacode reader such as a cell phone could take a picture or scan the code to grab the Computer Hope URL (http://www.computerhope.com/).
- The official semacode page and a semacode generator and links to other semacode generators can be at: http://semacode.org/.
