Description

The present invention relates to an information processing apparatus , an IC card, and an electronic money system for reading and writing information between IC cards having two LSIs.

  In recent years, as an IC card, a hybrid card in which an LSI (contact LSI) having a contact interface (contact terminal) and an LSI (non-contact LSI) having a non-contact interface (non-contact antenna) are mounted on one card. Has been developed (see, for example, Patent Document 1). This hybrid card is realized simply by incorporating the existing contact circuit (contact LSI, contact terminal) and non-contact circuit (non-contact LSI, non-contact antenna) into a single card. Although it is possible, for example, data written to the contact LSI via the contact interface cannot be read out via the non-contact interface, and data written to the non-contact LSI via the non-contact interface can be contacted. It cannot be read out via the interface. That is, this hybrid card cannot exchange data written to the contact LSI and data written to the non-contact LSI.

  On the other hand, a combination card equipped with an LSI (combination LSI) having a contact interface (contact terminal) and a non-contact interface (non-contact antenna) has been developed. This combination card can write data from both the contact interface and the non-contact interface to one LSI, and can read data from the LSI via the contact interface or the non-contact interface. However, the combination LSI is more expensive than the contact LSI and non-contact LSI described above, and there is a problem that the manufacturing cost is increased.

Therefore, it is desired to develop a system that can exchange data between two LSIs using a hybrid card that can be manufactured at a relatively low cost.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a block diagram of a configuration of an information processing system 1 (hereinafter simply referred to as system 1) according to an embodiment of the present invention. FIG. 2 shows a hybrid card C used in this system 1. A circuit configuration (hereinafter simply referred to as a card C) is shown.

  As shown in FIG. 1, the system 1 includes a card C and an information processing apparatus 10 (hereinafter simply referred to as a processing apparatus 10). As shown in FIGS. 1 and 2, the card C has a contact LSI 4 having a contact terminal 2 (contact interface) and a non-contact LSI 8 having a non-contact antenna 6 (non-contact interface).

  As shown in FIG. 1, the processing device 10 includes a contact interface 11 connected to the contact terminal 2 of the card C and a non-contact interface 12 for transmitting and receiving data to and from the non-contact antenna 6 of the card C. A main control unit 15 that controls the operation of the processing device 10; a contact control unit 13 that transmits and receives data to and from the card C via the contact interface 11 in response to a command from the main control unit 15; 15 according to the command from 15, the non-contact control unit 14 that transmits / receives data to / from the card C via the non-contact interface 12, and the data acquired by the main control unit 15 via the interfaces 11, 12 are constant. Commands from the holding unit (SAM (Secure Application Module)) 18 and the main control unit 15 that hold a level of security higher than the level. Accordingly, a SAM control unit 16 that reads / writes data from / to the SAM 18 via the SAM interface 17 is provided.

  Hereinafter, processing operations when the above-described system 1 of the present invention is applied to an electronic money system will be described with reference to FIG. Here, description of the operation of the detailed configuration of the processing apparatus 10 is omitted, and data exchange between the SAM 18 and the card C will be mainly described.

  In the electronic money system, a contact interface with a relatively high security is used when the balance of the card C is replenished, and a contactless interface with a relatively high processing speed and high convenience is used for the payment process. desirable.

  When replenishing the balance of the card C, as preprocessing 1, the processing apparatus 10 reads the balance of the non-contact LSI 8 via the non-contact antenna 6 of the card C and proceeds to the SAM 18. Then, as preprocessing 2, the processing apparatus 10 writes the balance transferred to the SAM 18 to the contact LSI 4 via the contact terminal 2 of the card C.

  Thereafter, the processing device 10 writes the amount replenished in advance via an input unit (not shown) to the contact LSI 4 via the contact terminal 2 of the card C as a balance replenishment process, and updates the balance of the contact LSI 4. To do.

  Then, as post-processing 1, the processing apparatus 10 reads the updated balance from the contact LSI 4 via the contact terminal 2 and proceeds to the SAM 18. Further, as post-processing 2, the processing apparatus 10 writes the updated balance transferred to the SAM 18 to the non-contact LSI 8 via the non-contact antenna 6. Thus, the balance replenishment process is completed.

  On the other hand, in the payment process of the card C, the processing device 10 reduces the balance from the non-contact LSI 8 via the non-contact antenna 6 according to the payment amount input in advance, and updates the balance of the non-contact LSI 8 To do.

  As described above, according to the present embodiment, a relatively inexpensive hybrid card having a contact LSI and a non-contact LSI can be incorporated into the system, and in addition, data to be written to the contact LSI and the non-contact LSI The compatibility of the data to be written to the card can be provided, and the same function as the combination card can be realized.

  Further, in the case of a card having a contact LSI and a non-contact LSI, such as the card C of the present embodiment, it is possible to arbitrarily and freely combine LSIs from different manufacturers as long as each LSI is certified for use. It is possible to increase the degree of freedom of design. On the other hand, in a combination card equipped with one LSI having two interfaces, it is necessary to obtain two types of use certification for contact and non-contact use, and it is necessary to recertify every time the combination is changed. There is a problem that lacks convenience.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above.

  For example, in the above-described embodiment, the case where the system of the present invention is applied to an electronic money system has been described. However, the present invention is not limited to this, and other methods such as finance, distribution, transportation, medical care, security, industry, public, and biometric authentication are used. The system of the present invention can also be used in the information processing system.

  In the above-described embodiments, the case where the SAM is used as a holding unit that holds data to be read / written to / from the LSI in a high security state has been described. However, the present invention is not limited to this, and an HSM (Hardware Security Module), a contact IC card is used. Other holding means such as a non-contact IC card may be used.

  Further, in the above-described embodiment, data read from the non-contact LSI 8 of the card C via the non-contact interface 12 is temporarily written to the contact LSI 4 via the contact interface 11 via the SAM 18 for data processing. Thereafter, data is read from the contact LSI 4 via the contact interface 11 and written to the non-contact LSI 8 via the non-contact interface 12 via the SAM 18, but the data processing flow is reversed. good. That is, data read from the contact LSI 4 of the card C via the contact interface 11 is temporarily written to the non-contact LSI 8 via the non-contact interface 12 via the SAM 18, and after the data processing, the non-contact interface 12 is processed. It is also possible to read out data from the non-contact LSI 8 via the contact and write it into the contact LSI 4 via the contact interface 11 via the SAM 18. That is, according to the present embodiment, data recorded in the contact LSI 4 and data recorded in the non-contact LSI 8 can be exchanged with each other.
