Abstract
Systems and techniques for recognizing and distinguishing between different containers in which products to be sold by weight may be placed before purchase. A point of sale terminal includes devices for capturing and evaluating information relating to the presence, absence and identity of container type indicia whose presence characterizes a container as belonging to a particular type having a particular weight. Containers in which products may be placed are given appropriate indicia. When an item is to be sold by weight, the item is weighed and a weight reading is received. Information relating to the presence, absence and identity of indicia characterizing a container type is captured and evaluated, and if a container bearing such indicia is identified, the container weight is subtracted from a weight reading to obtain a net weight for the products.
