A low profile tri-aperture optical code scanner and operating method are presented. The scanner includes three scanning apertures and a front and a rear low profile housing component. Each housing component includes a scanning aperture tilted toward a point about the center of the scanner. A third scanning aperture is located in a horizontal top surface of the scanner. The low profile housing elements allow an operator to scan items by standing either on the front side or the rear side of the scanner. When used in a convertible point of sale terminal, a cashier operates the scanner from the front side of the scanner when the terminal is in the assisted mode and a customer operates the scanner from the rear side of the scanner when the terminal is in the self-service mode. |
