Abstract: Signature verification systems are disclosed utilizing a hand held writing implement (10) used to combine a user's fingerprint pattern and their hand written signature. A prism detector (14) is scanned by a laser diode (16) and the resultant image is optically transmitted onto either a writing surface specifically designed to receive this image or directly intergrated with use of an optical ballpoint (110) into the applied ink simultaneous to inscription on the writing surface. Detection array (72) converts this optical image into signals appropriate for data interface and processing for use in on line verification systems which can be used at point of signature locations where a user may seek positive identification.
