A fingerprint sensing device and recognition system includes a capacitive array of sense elements. 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 also features a spacer or spacers to allow for a reproducible sensing of the same fingerprint. Optionally, the spacer or spacers include a roller or rollers, which further optionally in conjunction with a monitoring device for determining motion of a surface being imaged device. Also optionally, th sensing devices includes a guiding channel as to allow for a well defined motion of the biological surface to be imaged. A method for sensing a biological surface using the fingerprint sensing device is also disclosed.
