Abstract: Systems, methods and machine-readable media operate on configuration data for wagering game machines. A wagering game machine configuration or meter data on a wagering game machine is modified. In response to the modification, the configuration data or meter data is transformed into a displayable code such as a bar code or QR (Quick Response) code. The wagering game machine presents the displayable code on a code display of the wagering game machine. A portable computing device reads the displayable code and uses the displayable code to compare the configuration data with configuration data obtained from other wagering game machines or configuration data obtained from a configuration server.
