## Abstract

A unified IC card includes: 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 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The unified IC card according to claim 1, wherein when the user clicks the selection part, the selection part is converted from a turn-off state into a turn-on state or from a turn-on state into a turn-off state.

### Claim 3 (depends on 2)

The unified IC card according to claim 2, wherein when the user clicks the locking part, the selection part is converted from an unlocked mode into a locked mode or from a locked mode into an unlocked mode.

### Claim 4 (depends on 1)

The unified IC card according to claim 1, wherein the selection part comprises a first connection part physically or electrically connected with the information storing part and the information storing part comprises a second connection part physically or electrically connected with the first connection part, wherein the first connection part and the second connection part are connected with each other detachably.

### Claim 5 (depends on 1)

The unified IC card according to claim 1, wherein the information storing part further comprises a separation preventing part for preventing the selection part from being separated.

### Claim 6 (depends on 1)

The unified IC card according to claim 1, wherein the IC chip part adds, deletes and changes company information of the card applet, the financial card applet, the stock card applet, the point card applet, and the associated card applet and the user's individual information in the manner of a communication type card.

### Claim 7 (depends on 1)

The unified IC card according to claim 1, wherein the selection part further comprises a selection indicating part to inform the user of the selection.

### Claim 8 (depends on 1)

The unified IC card according to claim 1, wherein the locking part further comprises a locking indicating part to inform the user of whether the selection part is in the locked mode or in the unlocked mode.
