  • Method and apparatus for determining a stable weight measurement for use in a security software application of a self-service checkout terminal
    Patent number: 6215078
    Abstract: A method of operating a retail terminal having a weight scale associated therewith includes the step of executing a security software application so as to provide security to the retail terminal during operation thereof. The method also includes the step of determining a current weight value associated with output from the weight scale.
