ABSTRACT:
A data capturing module combined with a portable data terminal of the hand-held type to record handwritten data. Using a digitized pad, the module can provide for direct input of handwritten data into the system, or a peripheral digital scanner can be employed to provide for data entry. Depending upon the particular application, the module therefore provides for data entry of handwritten text or graphics using the data terminal and other components of a portable data system to enter, display, print or otherwise communicate the handwritten data.
