Abstract: A system for gathering data on behavior of shoppers in a retail market. A scanner is attached to a shopping basket, and detects (1) removal of an item from a shelf, (2) the identity of the removed item, (3) insertion of an item into a shopping basket, which may be the identical item removed from the shelf, and (4) the identity of the inserted item. Repeated detection of this type of data for numerous items, and numerous shoppers, allows one to draw valuable inferences about the shoppers, such as how often comparison shopping occurs. This type of detection also allows one to take specific responses to the actions of the shoppers.
