hardlink

A hardlink is a method of hyperlinking objects in the real world, including graphical tags (QR code), SMS tags, and RFID tags. The hardlink method establishes a reference link between a physical world object and a .mobi web page, just as a traditional hyperlink establishes an electronic reference to information on a web page.

A cell phone is the medium of this information exchange that is initiated whenever a user makes a connection with a hardlink database and enters an alphanumeric sequence found on the target object. As of 2009, unlike Japan, few U.S. cell phone providers offer graphical tag readers or other support for hardlinking methods.
