ABSTRACT:
An identification system includes several sheets formed of digital paper each having a unique identifier on a writing surface thereof. Each digital paper may have a form printed on the writing surface. Data representing the form and the location thereof relative to the writing surface is stored in a computer. A digital pen connectable to the computer is compatible with the digital paper for recording pen strokes made by the digital pen and the location of the pen strokes relative to the writing surface. The digital pen includes an ink dispensing tip for marking the writing surface according to the pen strokes. The computer is connectable to the digital pen for retrieving and storing the data representing the pen strokes for each sheet. Upon completion of a form, the computer compares the data representing the pen strokes with the form data and determines the user input to the form.
