A POS-based system including (i) a system housing having a horizontal housing portion and a vertical housing portion. The vertical housing portion is configured substantially orthogonal with respect to the horizontal housing portion. At least one reading window is formed in the system housing. A support frame having a plurality of spaced apart support surfaces, supports the system housing when the system housing is position over the support surfaces. A convex weigh surface is integrated with the vertical housing portion, for supporting the weight of produce items supported thereon during weighing operations. A code symbol reading subsystem is disposed in the system housing, for optically reading code symbols on objects being transported through a 3D reading volume definable relative to at least one code symbol reading window, and producing symbol character data representative of the read code symbols. An electronic weigh scale subsystem is provided including a base portion having a plurality of load cells for measuring the weight supported thereupon.
