Abstract
A method of operating a self-service checkout terminal includes the step of detecting an improper-terminal-use activity and generating an improper-use control signal in response thereto. The method also includes the step of operating a status device in a first mode of operation in response to generation of the improper-use control signal. The method further includes the step of updating an electronic log value in response to generation of the improper-use control signal. Moreover, the method includes the step of generating a first intervention signal if the log value has a predetermined relationship to a log threshold. The method also includes the step of operating the status device in a second mode of operation in response to generation of the first intervention control signal, wherein the first mode of operation is different from the second mode of operation. The method yet further includes the step of generating an end-of-itemization control signal in response to a user's indication that the user has no further items to enter into the checkout terminal. The method also includes the step of operating the status device in a third mode of operation if (1) the end-of-itemization signal has been generated, and (2) the status device was operating in the second mode of operation when the end-of-itemization control signal is generated, wherein the third mode of operation is different from each of the first mode of operation and the second mode of operation.
