Abstract
A hand biometrics sensing device includes an array of sensing elements (12) defining a sensing area (11) over which a person's hand is placed and which has a first portion (14) in which the sensing elements are arranged to provide high resolution sensing suitable for sensing fingerprint patterns and a second portion (15) in which the sensing elements are arranged to provide lower resolution sensing suitable for sensing at least one other hand biometric characteristic, for example, hand geometry, finger length, width or inter-joint dimensions. The sensing elements, which may include sense electrodes (17) connected to switching devices (16) such as TFTs, are arrayed in rows and columns and addressed by peripheral drive circuits via sets of row and column address conductors (18, 20), resulting in a low-cost, compact device.
