Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mobile SIM card,

The present invention relates to a SIM (Subscriber Identity Module) card for extending a mobile supplementary service including a Secure Element (SE) function and a mobile communication terminal equipped with the same.

Recently, with the opening of the mobile environment, the conventional closed financial card has been liberalized, and thus the mobile payment service market has become more dominant in the mobile payment market.

That is, the dominance of the mobile communication carrier for the security module of the mobile communication terminal and the UICC (Universal Integrated Circuit Card) is strengthened. The security module is used to store important personal information such as credit card, membership number and coupon. It uses RF wireless technology based on important personal information stored in the security module to exchange information with mobile communication terminals or with merchant payment terminals Exchange.

At this time, the security module may be located in a USIM (Universal Subscriber Identity Module) having the initiative of the mobile communication terminal, or may be located in an IC chip SD card or the like embedded in the mobile device. Currently, various projects using mobile are developed into USIM, which has the dominance of mobile communication companies. In order to gain vested interest in the operation of security module, which is the core of business, various security modules that can be applied to mobile are developed and tried have.

In order to apply various security modules such as a SD (Secure Digital) card and a built-in SE to a mobile communication terminal including a smart phone, a technology applicable to a currently developed mobile device should be implemented. However, There are many difficulties in applying the present technology and conditions.

This means that financial institutions (banks, credit cards, memberships, etc.) and other card companies that have used their applications in the existing smart cards have been trying to deploy mobile-based financial services based on mobile convergence. However, In order to share the module, it is difficult to find a consensus on the business because it is afraid to depend on it for various reasons such as obtaining the approval of the mobile communication carrier.

The key of the service is issuance using the customer information through the attracting of the subscriber to all businesses such as a transportation card, a bank card, a credit card, and a communication card, and generates a unique cryptographic key set for each card based on issuance, Encryption, and subscriber finance, traffic, service, and network network services.

Therefore, recent liberalization by mobile payment has been divided into one that worries that it will develop on the basis of a security module of a mobile communication provider and the other side that finds a consensus, and a new breakthrough security module This is a situation that is urgently needed both domestically and globally.

For this reason, various security modules have recently been tried in China or in the financial sector. Among them, a security module and a micro SD card are embedded in the mobile. In the case of a micro SD card, most mobile communication terminals support the function, but due to expensive card production costs such as a connection to an NFC (Near Field Communication) antenna and a memory to be basically installed in an SD card, There is a lot of work to be done. In the case of a micro SD card, in order to perform NFC-based financial settlement, it is necessary to implement an interface with an NFC chip or a function of a self antenna, but not all SD cards and NFC chips are applied to an NFC mobile device , There is a problem in antenna matching when connecting to the antenna itself, so that there is a lot of difficulty in actually using the antenna.

Meanwhile, as described above, since the security module is located in the USIM area, besides the way in which a credit card company, a membership, a coupon issuer, and the like must perform cooperation business under the jurisdiction of a mobile communication service provider, A memory area not controlled by a mobile communication carrier, etc.), it is possible for a credit card company, membership, coupon issuer, and the like to perform service provision without having to associate with a mobile communication provider. However, the development of technologies and services for enabling such services are not realized at present.

16, the SIM card 300 may be mounted in the socket 130 inserted into the mobile communication terminal body 100 together with the USIM card 200, One end of the fourth connection member 400 is electrically connected to the mobile communication terminal body 100 and the other end of the fifth connection is electrically connected to the USIM card 200 Member 410 and is coupled to a socket 130 inserted into the insertion port 140 of the mobile communication terminal body 100. That is, the USIM card 200 and the SIM card 300 are coupled to the socket 130 and then inserted into the insertion port 140 of the mobile communication terminal body 100.

It is preferable that the SIM card 300 described in the embodiments of FIGS. 14 to 16 is formed of a thin and flexible material including a flexible PCB.

17, the SIM card 300 may include a UICC slot 110 provided in the mobile communication terminal body 100 of FIGS. 14 and 15, or a UICC slot 110 provided in the mobile communication terminal 100 of FIG. It is possible to stack one or more layers according to the thickness of the socket 130 inserted into the insertion hole 140.

In this case, the SIM card 300, which is stacked one or more times, can be configured to transmit data through NFC communication when using the function of the SIM card 300 by combining with the single antenna 320, The antenna 320 may be incorporated or coupled to transmit data through NFC communication when the function of the SIM card 300 is used.

Unlike the example described with reference to FIG. 17, the SIM card 300 may be used in combination with one or more of the SIM cards 300 in the longitudinal direction as shown in FIG.

It will be apparent to those skilled in the art that various modifications may be made to the invention without departing from the spirit and scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
