web2.0 graff via the 3rd-screen
QR-Codes and Semacode tags can be quickly captured with a mobile phone’s camera which are then decoded to obtain a Web site address and accessed via the phone’s web browser. The difference between the two is that Semacode has a single defined markkup: the contents are a URL and can not be changed to have further markups without breaking backwards compatibility. Potentially new URL types could be introduced, a URL pointing to address book information for instance. The advantage QR code has is that there are defined markups for different types of information (incompatible ones from the various vendors but probably be resolved), and the default for “unknown markup” is “interpret it as text and look inside it for obvious URLs or whatever.”
