1. An input device for use in a dynamic handwritten pattern verification system, particularly for a signature verification system, comprising:

  • (a) a housing having a hand-held barrel extending along an axis and terminating in a writing tip;

    (b) positioning means on the barrel adjacent the tip for positioning a plurality of fingers of one hand of a writer forming a handwritten pattern in a one-handed writing configuration at a plurality of preselected locations on the barrel;

    (c) barrel pressure transducer means for sensing radially-inwardly-directed writing pressure by said fingers against the barrel during forming of the handwritten pattern, including at least one transducer located at one of the preselected locations in a force-transmitting relationship with the respective finger positioned thereat to convert radially-inwardly-directed writing pressure exerted by the respective finger on the barrel to an electrical output signal; and

    (d) means for conducting the electrical output signal to the verification system.
