A system displays information on one or more products or services to a shopper using an easily-controlled system for selecting the displayed information. The system uses a display device capable of retrieving information from local or remote memory for display in response to these commands from a shopper. The user controls the display device by physical motion of the display in communication with one or more nearby display cards containing one or more triggering symbols representing a product or service of interest. The display device senses the selected trigger and displays information related to the selected product or service. The shopper may also select differing types of information using the user camera and touch capability of the display device.
