Abstract

Products are dispensed from a dispensing apparatus in which products marked with transaction information are received in a chain of bins. In response to control information synthesized from transaction information on the products in the bins and a dispense request, the chain is moved to place a bin at a dispensing station on the dispensing apparatus. At the dispensing station, a mechanism is operated in response to the control information to provide access to the bin. A product in the bin may then be retrieved.
