In addition, since the mobile phone 70 can be connected to many business-side devices via a wireless communication network such as the Internet or a non-contact IC reader / writer, the types of business-side devices that can be selected In other words, the types of company memory 50 that can be attached to the IC card 40 increase, and the usage of the IC card 40 can be further expanded.

  By the way, when a user contracts with a business operator and communication is permitted, information for performing communication with a device on the business operator side is downloaded via the Internet, and a memory built in the mobile phone 70 is stored. However, the operation is complicated, and depending on the communication status, it may not be downloaded normally. In addition, the user may forget the contracted business operator. However, according to the IC card 40 of the present embodiment, it is possible to communicate with the contracted business by simply mounting the business memory 50 of the contracted business on the IC card 40, Since the information indicating the business operator is marked in the business operator memory 50 attached to the IC card 40, the contracted business operator can be easily confirmed by removing the IC card 40 from the mobile phone 70. .

  Furthermore, when various types of information are stored in a memory built in the mobile phone 70, when the information is deleted, the unnecessary information must be deleted by operating the mobile phone 70. The operation is complicated and troublesome. Then, it is difficult for the user to determine whether or not the information has been securely deleted, and there is a possibility that the information remaining in the memory may be read illegally. However, by using the IC card 40 of the present embodiment, by removing the business operator memory 50 that is no longer needed, information for the mobile phone 70 to communicate with the business operator is completely erased from the mobile phone 70. Information security can be improved.

  For example, when the mobile phone 70 is used for an electronic ticket, electronic money, identification card, or the like, the operator memory 50 is added or changed, so that the operator can be added or changed. Can be easily performed, and can also easily cope with upgrades of services provided by each operating company.

In the second embodiment described above, the business operator memory 50 corresponds to the storage means of the present invention, and the processing of S310 to S440 corresponds to the communication control means of the present invention.
As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.

  For example, in the first embodiment, the card body 2 is provided with a mounting portion 2b formed of a recess on the front surface, and the operator memory 30 is fitted and bonded from this surface to attach the operator memory 30 to the card body 2. Although it is configured so as to be mounted, it may be configured such that an operator memory insertion portion is formed on the side surface of the IC card 1 and the operator memory is inserted from the side surface.

  Further, in the first embodiment, the user is authenticated by the personal identification number inputted to the apparatus on the business operator side from the outside, but this is not limited to the personal identification number, and the fingerprint, face image, The user may be authenticated by the biometric authentication technology based on the ecological characteristics of a person such as the retina. In this case, information on the user's ecological characteristics may be registered in advance in the operator memory 30 instead of the user's personal identification number.

  Then, the IC card 1 of the first embodiment is configured such that the connection terminal 14 of the IC module 4 built in the IC card 1 and the electrical contact of the device on the business side mechanically contact each other, thereby making the IC module 4 Is a contact IC card that operates upon receiving power supply, but an antenna is formed on the pattern substrate 6 and electric power is generated by a magnetic field formed by the non-contact IC reader / writer. You may make it provide the function as a non-contact IC card which performs radio | wireless communication between. If it does in this way, the kind of apparatus of the provider side which can be used increases and it can expand use use more.

  On the other hand, in the IC card 40 of the second embodiment, a plurality of operator memories 50 storing information for allowing the mobile phone 70 to communicate with the operator's device in advance are mounted, but nothing is stored. A non-operator memory 50 (hereinafter referred to as a blank memory) may be installed in advance. In this way, for example, by shipping the mobile phone with the IC card 40 having a plurality of blank memories inserted, while allowing the store to store information in the blank memory, the user can When purchasing a mobile phone, the operator who wants to use can be selected. Also in this case, when the user cancels the contract of the business operator, the content stored at the time of the contract is discarded by removing the business operator memory 50 from the IC card 40, which is convenient.

  In the second embodiment, the communication terminal into which the IC card 40 is inserted is the mobile phone 70 with a built-in non-contact IC tag. However, the mobile phone 70 may not have a built-in non-contact IC tag. Further, an antenna that constitutes a non-contact IC card by being connected to the IC module 4 of the IC card 40 may be incorporated. In this case, since the IC card 40 has a function as a non-contact IC card by being connected to an antenna built in the mobile phone 70, the IC card 40 can be connected to the non-contact IC reader / writer while being inserted into the mobile phone 70. Wireless communication can be performed between them.
