A shopping cart display system includes a cart mounted display that is responsive to unique trigger signals provided by respective transmitters associated with respective fixed locations. When the display receives a unique trigger signal, it displays advertising associated with the respective location. In one embodiment, the display includes a sensor for determining whether the information is displayed in the presence of a customer, and a memory for storing all trigger signals received during a given shopping trip. The stored data are transmitted to a polling transceiver located at a point of sale register for later analysis. Provision is made for the customer to request and receive information, such as deli numbers.
