Abstract:
It is described an arrangement (560, 660, 760) for fingerprint sensing/verification, comprising: a sensor system (100) comprising plural sensor capacitors (101), each sensor capacitor including a central electrode (103) and a peripheral electrode (105) annularly surrounding the central electrode and being connected to a ground potential; wherein changes of the electric fields between each of the central electrode and the peripheral electrode of the plural sensor capacitors upon positioning a finger (317) close to the sensor system is used to detect the fingerprint.
