Abstract
A card structure provides an existing card having an associated card service and further having at least one associated service of at least one other card that is used by a card user. A display is coupled to the card structure for displaying desired information on the overloaded card. The overloaded card display comprises a silicone sheet display having embedded thereon an array of electrostatically chargeable balls. An electric charge is applied to each of the balls so that each of the balls is in a desired position to display the information on the overloaded card. The card is read by a reader at a card terminal, and an array of electrodes that charge and manipulate the balls face the display to charge them so that images programmed at the electrodes are left thereon.
