Device for biometric identification with the aid of fingerprints and/or hand characteristics, and method of biometric identification with the aid of these characteristics

Abstract

The invention relates to a device for biometric identification with the aid of fingerprints and/or hand characteristics, the device comprising a sensor unit () directed at the region of an optical gate () in a scanning direction (S), wherein the optical gate () is adapted to initialize the sensor unit () for scanning an in-focus scan image or scan images of the fingers and/or hand of a person, wherein the device further comprises at least one light source (), which is likewise directed at the region of the optical gate (), wherein the sensor unit (), the optical gate () and optionally also the light source () are coupled to a control and computing module () with software for controlling the device and its parts and for scanning a scan image or the scan images of fingers and/or a hand, and for evaluating the fingerprints and/or hand characteristics, wherein the sensor unit () is fixedly set to focus into a focal volume () which is assigned to the optical gate (), and the sensor unit (), the optical gate (), the control and computing module () and optionally also the light source () are configured to scan a single in-focus scan image of the fingers and/or the hand at the time of the passage thereof through the focal volume ().
