Card-sized electronic data storage device employing an electronic-ink layer for displaying graphical indicia
First Claim
1. A card-sized electronic data storage device comprising:
- (1) an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material disposed between an activation layer and a transparent electrode layer located above said layer of electronic ink, for activating said layer of electronic ink at particular locations to display graphical indicia on the surface of said addressable display assembly, wherein said layer of electronic ink does not require electrical power to maintain the display of said graphical indicia;
(2) at least one antenna structure for receiving electromagnetic data signals carrying information corresponding to instructions, programs, data and/or graphical indicia to be displayed by said addressable display assembly;
(3) an integrated circuit structure having (i) a storage element for storing said instructions, programs and data, and (ii) a programmed processor using said programs to process said instructions and data for (i) determining the graphical indicia to be displayed by said addressable display assembly at any moment in time, (ii) controlling and coordinating operation of said addressable display assembly, and (iii) generating output signals for instructing said addressable display assembly to display the determined graphical indicia; and
(4) a signal receiving structure, operably connected to said integrated circuit structure and said at least one antenna structure, for receiving electromagnetic data signals from an activation module, using said at least one antenna structure;
wherein said received electromagnetic data signals carry information corresponding to said programs, said instructions, said data or said graphical indicia to be displayed by said addressable display assembly;
wherein said integrated circuit structure is responsive to electromagnetic data signals received from said activation module, by said at least one antenna structure and said signal receiving structure; and
wherein said addressable display assembly is responsive to said output signals generated by said programmed processor, to display the determined graphical indicia on said addressable display assembly.

Abstract
A card-sized electronic data storage device including an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material. The card-sized electronic data storage device includes an integrated circuit structure having a storage element for storing instructions, programs and data. The integrated circuit structure also includes a programmed processor in communication with the storage element. A signal receiving structure receives electromagnetic signals from an activation module, using the antenna structure. The card-sized electronic data storage device displays the determined graphical indicia on the addressable display assembly. The graphical indicia can represent information relating to many possible objects, including, for example, a financial account, a points-based account, a monetary account, a membership, a promotion service, a travel-related service account, a charge account, a credit account, a debit account, a bonus account, or an identification card.
