Abstract
A smartcard devicethat includes a single embedded IC chipthat includes smart card circuitry that includes a processor device and memory that is shared with a fingerprint capture device () that has a plurality of charge storage devices (), i.e., the shared memory, that couple through conductive surfaces () to conductive spheres () that are disposed within an epoxy that comprises a fingerprint contact surface (). When raised portions of an object () appropriately contact certain conductive spheres (), the corresponding charge storage device () 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.
