A method of providing security to a self-service checkout terminal having a bagwell and a light curtain device that generates a light curtain which is positioned over the bagwell includes the step of locating a grocery container in the bagwell. The method also includes the step of generating an item-entered control signal when a product code associated with an item is entered into the terminal. The method further includes the step of advancing the item through the light curtain and into the grocery container and generating a first detection control signal in response thereto. Moreover, the method includes the step of generating an invalid-use control signal when the first detection control signal is generated prior to generation of the item-entered control signal. A self-service checkout terminal is also disclosed.
