Abstract
A placard for displaying a customer specific message includes a receiver, a capacitor, and an electronic updateable static display. The receiver has a memory storing an identification code and an antenna for receiving a signal. The capacitor is coupled to the receiver and capable of being charged by the signal. The electronic updateable static display is coupled to the receiver, is powered by the capacitor and is capable of displaying customer specific messages when a portion of the signal matches the identification code of the placard. A method of using the placard for displaying a customer specific message is also provided.

32. A method of using the system comprising:
-
generating a signal having one or more placard identification codes and an customer specific message associated with each of the placard identifications from a database;
transmitting the signal using a transmitter and one or more antennas;
receiving the signal on an antenna coupled to a receiver;
charging a capacitor coupled to the receiver on each of the one or more placards using the energy received from the signal; and
displaying the customer specific message on an electronic updateable static display, which is coupled to the capacitor and the receiver, by using the energy from the capacitor when a portion of the one or more placard identifications is the placard receiving the signal. - View Dependent Claims (33, 34, 35, 36, 37, 38)
