Title:
FINGERPRINT BASED SMARTCARD
Document Type and Number:
WIPO Patent Application WO2005058004
Kind Code:
A8
Abstract:
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.
