A shopping cart display system is provided to present product advertisements to consumers who do not have this information. This 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 determining whether the information is displayed in the presence of a customer, and a memory for storing all signals received during a given shopping trip and the times that those trigger signals were received. The stored trigger signals may then be used to analyze the path of the shopping cart. 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.
