Abstract
A fingerprint sensing device and recognition system includes a capacitive array of sense elements in conjunction with a means of determining motion of a surface being imaged. A plurality of images is combined to form a composite image having an area that is greater than the area of a single captured image. The sensing device is disposed between protective surfaces and supported by a flexible structure.
