A passive transparent media adapter magnetically couples to a scan system. The transparent media adapter captures light from an existing scan module and transfers the light to backlight transparent media so that it can be imaged by the scanner module. The transparent media adapter has no active electronics or illumination so does not require control or power to operate. The magnetic coupling allows a significant amount of existing system illumination to be focused into a narrow backlight region that moves in sync with the scan module.
