Scanner/scale configuration is performed without scanning a series of programming barcodes and performed when a terminal is in a transaction processing mode of operation. A single code scanned into the scanner, initiates a configuration tool on the terminal and causes a graphical user interface (GUI) window to be rendered on a display of the terminal on top of any transaction windows rendered on the display. The GUI window permits user-defined configuration of the scanner/scale. In an embodiment, the configuration tool also provides a clone code that represents a source scanner/scale's configuration settings, when the clone code is scanned into a target scanner, the source scanner/scale's configuration settings are cloned on the target scanner/scale.
