ABSTRACT:
A handwriting capture device which employs a highly sensitive digitizer to accurately capture signature information entered using a writing force greater than or equal to a predetermined writing force. The handwriting capture device includes a housing having a top surface, a resistive membrane digitizer mounted in the top surface and having a low pattern density, a layer of urethane rubber for frictionally holding the receipt in place, circuitry for processing digitizer information, a clamp for retaining a receipt in place over the digitizer during movement of the device, and circuitry for sensing the presence of the receipt and for activating data capture by the digitizer when the receipt is positioned under the clamp. In the preferred embodiment, the clamp also serves to minimize finger contact with the digitizer.
