Semacode
A camera phone, pictured, is the center of the semacode system. The user must have an internet connection plan using GPRS or a more advanced data option. When they encounter a semacode in the wild, they load up the semacode software and point the viewfinder at the symbol. With a single click, the software decodes the contents of the semacode and presents the URL onscreen for approval. If you accept it, the web address is launched in the on-phone web browser.
