A method and system of dispatching a non-digital merchandise andor allied services related code is described, via a device operable on a mobile communication network. Deployment pattern matching is further implemented by accessing a realization pattern that captures deployment parameters relating to resources and resource-resource relationships of a deployment of interest and expressing the realization pattern as a pattern graph defined by conceptual resource elements and constraints arranged by resource-to-resource relationship links and constraint links. The scanning optical unit has at least one optical surface that has a fine structure grating 8 having a grating pitch smaller than the wavelength of the light flux emitted from said laser light source.
