Software Activation Systems

We describe a method of activating functionality of an item of software installed on a mobile device, the method comprising: installing said software on said mobile device, wherein said installing includes registering in an operating system of said mobile device a link between an application URI scheme and said software such that a URI having said application URI scheme will be passed to said installed software for processing; scanning a code into said mobile device, wherein said code includes a code URI comprising said application URI scheme and activation data for said item of software; interpreting said application scheme of said code URI using said registered link to pass said code URI to said installed software; and processing said code URI using said installed software to activate a function of said item of software using said activation data in said code URI.
