An electronic ink stack ( 70 ) employs a pair of electrodes ( 71, 74, 78 ), an electronic ink layer ( 73 ), and an optional photoconductor layer ( 72, 76 ). The electronic ink layer ( 73 ) and the photoconductor layer ( 72, 76 ), if employed, are disposed between the electrodes ( 71, 74, 78 ). One or more location codes ( 75, 76, 79 ) are embedded within the electronic ink stack ( 70 ) in one or both electrodes ( 71, 74, 78 ), and/or the photoconductor layer ( 72, 76 ), if employed.
