A method of monitoring item shuffling in a post-scan area of a self-service checkout terminal having a post-scan shelf, a bagwell with a grocery container positioned therein, and a weight scale positioned so as to detect weight of items positioned both on the post-scan shelf and in the grocery container, includes the step of detecting removal of a first number of items from the post-scan shelf with the weight scale and generating a first weight decrease value in response thereto which corresponds to the weight of the first number of items. The method also includes the step of detecting placement of a second number of items into the grocery container with the weight scale and generating a first weight increase value in response thereto which corresponds to the weight of the second number of items. The method further includes the step of comparing the first weight decrease value to the first weight increase value and generating a first match control signal in response thereto if the first weight decrease value matches the first weight increase value.

Method of monitoring item shuffling in a post-scan area of a self-service checkout terminal

An improved self-checkout system and method which reduces transaction time. The self-checkout system includes a carrier for carrying a selected product, the carrier being coupled to a weighing apparatus for generating a first signal indicative of the actual weight of the product, an RFID tag interrogator for interrogating an RFID tag attached to the product and receiving product identification information relating to the product, an interface that is responsive to the received product identification information for communicating with a product information database to obtain weight information relating to the product, and a processor being responsive to: the obtained weight information for generating a second signal indicative of the expected weight; and the first and second signals for generating an alert signal.
