Overloaded card information display
First Claim
1. A method of providing and using a host card with multiple card services, comprising the steps of:
- associating a host card having an associated card service with at least one other service, wherein said at least one other service is associated with at least one other card;
managing the host card with the at least one other card service within a networked server independent of altering any data on the host card, wherein said managing includes;
responsive to a specified vendor establishment being designated as associated with one of said at least one other card service, automatically charging said one of said at least one other card service when said host card is used at said specified vendor establishment, and charging another of said at least one card service responsive to no specified vendor being designated, and displaying information on a display on the host card in accordance with the managing of said host card.

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.

7. The method of claim 1, wherein said display comprises an electret ball array, said displaying further comprising:
-
placing said electret ball array under an array of electrodes within a card reading device; and
in response to reading the host card within the card reading device, applying an electric field from said array of electrodes to said electret ball array, wherein said electric field rotatably manipulates individual electrets within said electret ball array such that an image is displayed on said electret ball array.
-
-
8. The method according to claim 7, the step of applying an electric field from said array of electrodes to said electret ball array further comprising the step of:
programming individual electrodes within said array of electrodes to have either a positive or a negative charge.
-
9. A system of providing and using a card with multiple card services, comprising:
-
means for associating a host card having an associated card service with at least one other service, wherein said at least one other service is associated with at least one other card, means for managing the host card with the at least one other card service within a networked server independent of altering any data on the host card, wherein said managing includes;
responsive to a specified vendor establishment being designated as associated with one of said at least one other card service, automatically charging said one of said at least one other card service when said host card is used at said specified vendor establishment, and charging another of said at least one card service responsive to no specified vendor being designated, and displaying information on the host card in accordance with the managing of said host card. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
a display writer containing an array of electrodes that represents programmed images that is used in order to apply electric fields to an array of electrets within a host card display.

17. The system according to claim 16, wherein said array of electrets is embedded within a flexible flat silicon sheet, said array of electrets comprising electrically maneuverable balls that each have a white side and a black side.
-
18. The system of claim 17, wherein said flexible flat silicon sheet is impregnated with a lubricant such that said electrically maneuverable balls can freely rotate in response to an applied electric field.
