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. Moreover, the method includes the step of comparing the current weight value to a previous-stable-weight value and generating a weight change control signal if the current weight value is not within a predetermined tolerance range of the previous-stable-weight value. Yet further, the method includes the step of utilizing the current weight value during execution of the security software application in response to generation of the weight change control signal. A retail checkout terminal is also disclosed.
