ABSTRACT:
For protecting a semiconductor chips from an electric destruction due to electrostatic charges. A card-shaped information storage medium used for providing data information to an information processing unit comprising (a) a board member of an insulating material having an first occupation area for at least one semiconductor chip capable of preserving the data informations and a second occupation area for a plurality of communication terminals electrically coupled to the semiconductor chip, (b) a protective member covering the semiconductor chip and exposing the communication terminals to the outside thereof, and (c) a protective shutter movable into or out of the protective member for shifting a position of the information storage medium between a closed state and an open state. The communication terminals are covered with the protective shutter in the closed state, thereby preventing the communication terminals from a human body with the electrostatic charges.
