Pen-based computing

Pen-based computing refers to portable computers that use an electronic writing pad and a light-sensitive pen to input data into a computer. The writing is converted into digital input and stored in a file in the computer.

Pen-based computing is becoming increasingly popular because most people are comfortable using a pen. It is particularly useful for sales and service representatives, insurance agents, retail suppliers, delivery people, inventory clerks, and health care providers, who are often on the move.
