An apparatus for, and method of, imaging a target presented to a bi-optical, dual window, point-of-transaction workstation utilizes multiple imaging modules individually mounted for individual installation on, and individual removal from, a motherboard. Each module includes a solid-state imager having an array of light-sensitive sensors for capturing return light from the target over a field of view; a local controller externally of the imager for controlling the imager, for storing image data corresponding to the captured return light, and for interrogating the stored image data; and a daughterboard on which the imager and the local controller are both commonly mounted.
