ABSTRACT An apparatus for self-service check out which calculates, within a main computer, the cumulative total weight of items, based on pre-determined and pre-programmed weights, and compares the computerized cumulative total weight to the weight determined by a second weigh scale means which determines the total weight of all items placed in a receiving container means. Items scanned by electronic means are itemized by the computer which directs the printing of an itemized register tape. Fraudulent mishandling of items by the customer is overcome by communication between the computer and ending weigh scale when weights calculated by each correspond within a determined tolerance level. In an alternate embodiment, a weighing of pre-scanned items in total is required to correspond with the total weight calculated by the computer and the end weigh scale, within a determined tolerance level.
