<p>A signature scanner has a secure housing (10) with an aperture (14) exposing part (18) of a paper strip (19,22) for signature by a normal pen (28). After signature, a motor (36) moves the signature past a thickness sensor (30) which detects any overlaid signature and if so provides an alarm signal. The signature is scanned by a signature scanner (32) and an image transmitted to a central record point for validation. A printer (34) prints e.g. the time and date adjacent each signature. <IMAGE></p> |
