Unified IC card

A unified IC card comprising:

• a selection part allowing a user to select at least one of a card applet of various card companies, a financial card applet of various financial companies, a stock card applet of various stock companies, a point card applet of various point issuing entities, and an associated card applet of various affiliated companies;
• an IC chip part electrically connected with the selection part, the IC chip part storing and sharing card information of the card applet, the financial card applet, stock card applet, point card applet, and associated card applet and providing the card information of the specific applet selected by the user to the outside;
• and
• a locking part electrically connected with the selection part to control the operation of the selection part,
• wherein the selection part comprises:
• a sensing part embedded in the unified IC card for sensing pressure applied from the outside;
• a locking control part arranged between the sensing part and the locking part to control the selection part by receiving a control signal from the locking part;
• and
• an information storing part storing card information on the card applet, the financial card applet, the stock card applet, the point card applet, and the associated card applet,
• wherein the information storing part is a storing area different from the IC chip part embedded in the unified IC card and detachably mounted on the unified IC card for limiting sharing of security information stored in the IC chip part.
