Abstract
A retail terminal includes a scale for weighing items to be purchased. The scale is operative to obtain a settled or stable weight of items placed thereon either after a predetermined time delay from when the items were placed on the scale or the receipt of an actuation signal from a trigger or actuator. This allows time for the scanning of an item of the items on the scale via a scanner of the retail terminal generally associated with the lifting of the item from the scale in order for the item to be scanned.
