ABSTRACT:
A two-dimensional matrix symbology reader comprises a fixed housing having a slot disposed in a side of the housing to receive a card medium having a two-dimensional matrix symbology affixed thereto. The matrix symbology is illuminated within the housing once the medium has reached maximum axial extent of the slot. An aperture is disposed within the housing adjacent to the slot relative to the matrix symbology such that the light reflected from the matrix symbology is transmitted therethrough. The reflected light is then converted to information signals representative of the matrix symbology. Due to the controlled environment and uniform depth of field requirement within the housing, a pin hole aperture or lens can be utilized without the need for additional focusing or aperture control.
