A smartcard device 1200 that includes a single embedded IC chip 1222 that includes smart card circuitry that includes a processor device and memory that is shared with a fingerprint capture device ( 10 ) that has a plurality of charge storage devices ( 12 ), i.e., the shared memory, that couple through conductive surfaces ( 22 ) to conductive spheres ( 21 ) that are disposed within an epoxy that comprises a fingerprint contact surface ( 13 ). When raised portions of an object ( 26 ) appropriately contact certain conductive spheres ( 21 ), the corresponding charge storage device ( 12 ) will discharge through a separate conductive sphere which is connected to a grounded conductive surface. This discharging serves both to simultaneously sense the asperity features of the object and to store that sensed information as well.
