Abstract
A device is provided for reading information from a media containing randomly located encoded data in the form of a one or two-dimensional symbology is provided. The device comprises a housing having a slot capable of receiving the media therein to an axial extent thereof. The media is illuminated by a light source disposed within the housing. The light reflected from the media is received and converted into pixel data that includes data representative of the symbology. Thereafter, the symbology data is discriminated from among the pixel data, and the discriminated symbology data is converted into readable information signals. Alternatively, the device may comprise a housing having a window and a light source disposed within the housing capable of providing illumination through the window onto the media when positioned in proximity to the window. The light reflected from the media is transmitted through the window into the housing, where it is converted into pixel data that includes data representative of the two-dimensional symbology. The window may be disposed on a side of the housing facing horizontally, or may be disposed on an upper or lower surface facing vertically, or may b…
