Further, the hybrid card executes an operating system (hereinafter referred to as “OS”) program corresponding to the interface, thereby executing an application corresponding to the interface (hereinafter referred to as “contact application”, non-contact communication). An application corresponding to contact communication is referred to as a “non-contact application”) to perform processing.

  That is, as shown in FIG. 10, the IC card receives a message (command and data to be processed) from the external device A to the application A (credit) when the communication unit A communicates with the communication method A. The CPU executes the OS program corresponding to the communication method A, starts the application A, executes the program corresponding to the message, thereby realizing the message transmission / reception unit A, interprets the message, and sends a response message (response) Is generated. The message transmission / reception unit A transmits this response message to the external device A via the communication means A by the same communication method A as reception. When the communication unit B receives a message using the communication method B, similarly, the IC card performs processing by the message transmission / reception unit B and transmits a response message to the external device B via the communication unit B.

  Accordingly, in the process of writing individual application data to an unissued IC card and issuing an application, first, individual data for application A is written by communication method A, and then individual data for application B by communication method B. In order to write data, the communication method must be changed to perform two-stage processing, and there is a problem in that the load of the equipment for processing and the processing take time. The individual data of the application is data for each card and card attribute necessary for executing the program of the application.

On the other hand, there is an electronic information reading / writing device in which a SIM card is mounted on a mobile phone (for example, see Patent Document 1).
The SIM card includes a contact terminal which is a contact communication unit, and the SIM card can perform non-contact communication by connecting an antenna (non-contact communication unit) on the mobile phone side to the contact terminal. . However, when the SIM card is issued, the application B is installed, but since the SIM card is not attached to the mobile phone, individual data for the application B can be written via the non-contact communication means (antenna). There was a possibility that it could not be done.
In addition, if an individual SIM card is provided with an antenna that replaces the external antenna provided on the mobile phone side when the SIM card is issued, individual data for application B can be written. There was a problem that it took a burden to install.

FIG. 2B shows a non-contact transmission protocol command (used in contactless communication). FIG. 2 (c) shows the structure of an information field at the time of command reception in FIG. 2 (a) and FIG. 2 (b), and FIG. The structure of the information field at the time of response transmission in 2 (a) and FIG.
As shown in FIG. 2A, one frame (block) of the contact transmission protocol command is composed of a head field, an information field, and a last field. The node address (NAD) in the first field indicates the source and destination of the command block. The protocol control byte (PCB) stores protocol control information necessary for controlling data transmission. The length (LEN) stores the data length of the information field that follows.

As described above, the frame configurations of the transmission protocol commands (contact command, non-contact command, contact response, non-contact response) in contact communication and non-contact communication are different. In other words, the SIM card 10 receives two different specifications (types) of commands (contact command and non-contact command) using corresponding different communication methods.

FIG. 3 shows information fields at the time of command reception (FIG. 3 (a)) and response transmission (FIG. 3 (b)) of a contactless application access command and a contact application access command that can be used in the SIM card 10. FIG.

As shown in FIG. 3A, in the data field byte (DATA) of the contact application access command (non-contact application access command) at the time of command reception, the data (non-contact command) body data ( FIG. 3 (a ′)) is stored. Also, as shown in FIG. 3B, the data field byte (DATA) of the contact application access command (non-contact application access command) at the time of response transmission contains the data of the non-contact response body (FIG. 3 ( b ′)) is stored. The processing of the contact application access command (non-contact application access command) will be described later with reference to FIGS.

4 and 5 are diagrams showing the operation and program of the data carrier according to the present invention. FIG. 4 is an operation flowchart of the OS stored in the ROM 17, and FIG. 5 is an explanatory diagram. A portion surrounded by a dotted line in FIG. 5 indicates a program executed by the CPU 14. Hereinafter, the process of the CPU 14 (contact command control unit 141) will be mainly described.
As shown in FIG. 4, in step 100 (hereinafter, “step” is referred to as “S”), the SIM card 10 is connected to the issuance processing device 20A via the contact terminal 11 and transmits an initial response (ATR). The process is initialized and is in a state waiting for command reception.
In S110, the SIM card 10 receives a contact command (see FIG. 2A) from the issuance processing device 20A. The OS corresponding to contact communication (contact OS) identifies this command based on the command identifier, and is a normal contact command such as write (Write), which is a non-contact application access command (FIG. 3 ( If not a), the same processing as in the past is performed, such as calling and starting the contact application (S120, S190, # 10, # 40 in FIG. 5). The OS transmits a contact response as a processing result to the issuance processing device 20A, ends the processing for this command (S200), and again enters a command waiting state.

When the received contact command is a contactless application access command, the OS extracts the contactless command (see FIG. 3A ′) from the data field byte (S120, S130), and the RAM 16 Writing to the non-contact command response buffer (S140, # 20 in FIG. 5), the non-contact application is activated (S150, # 30 in FIG. 5). Control is transferred from the OS to the contactless application, and the contactless application reads and executes a command from the contactless command response buffer 161 (# 50 and # 60 in FIG. 5), and the result (response for contactless, FIG. 3). (See (b ′)) is written in the non-contact command response buffer 161 (# 50 in FIG. 5). Control returns to the OS (S160, # 30 in FIG. 5), and the OS reads this non-contact response (# 20 in FIG. 5). The OS sends the contact response (see FIG. 3B) storing the read non-contact response in the data field byte to the outside on the contact transmission protocol (S170), and performs processing for this command. The process is terminated, and a command waiting state is entered again (S180). Note that the non-contact command response buffer 161 is a temporary storage location of information formed in the RAM 16, and is referred to from either a contact communication side such as a contact OS or a non-contact communication side such as a non-contact application. Possible shared memory.
In this way, the issuance processing device 20A performs contact communication with the SIM card 10, and contacts the SIM card 10 with contactless application access commands including contactless commands such as a file selection command, a write command, and an authentication command. By transmitting, the individual data is written in the data area assigned to the contactless application in the nonvolatile memory 18 and the contactless application is issued.

As described above, according to the first embodiment, by performing contact communication between the issuance processing device 20A and the SIM card 10, the individual data of the contactless application is written to the SIM card 10 and the contactless application is issued. Became possible. That is, it becomes possible to issue a non-contact application without a holder having a SIM card antenna such as a mobile phone or a substitute antenna.
In addition, the contactless application access command that can be used in the SIM card 10 has a configuration in which a contactless command is included in the contact command, that is, a hierarchical configuration in which a conventional command configuration is multiplexed. The card 10 and the issuance processing device 20A can obtain the above-described effects by simple processing without performing particularly complicated processing. That is, the above-described effect can be obtained without significantly modifying conventional programs such as an OS used for controlling the SIM card 10 and the issuance processing device 20A. Regarding the response corresponding to the non-contact application access command, the contact response includes the non-contact response, so that the above effect can be obtained more easily.

FIG. 6 is a block diagram showing a configuration of the data carrier according to the second embodiment of the present invention. The data carrier in Example 2 is a SIM card 10-2. In addition, the same code | symbol is attached | subjected to the part which fulfill | performs the same function as Example 1 mentioned above, and the overlapping description is abbreviate | omitted suitably.
As shown in FIG. 6, the SIM card issuance system 1-2 includes a SIM card 10-2 and issuance processing devices 20A and 20B, and the issuance processing devices 20A and 20B and the SIM card 10-2 communicate with each other. Is a system for performing the issuing process of the SIM card 10-2, such as writing individual data of the application to the SIM card 10-2.
The issuance processing device 20B is a computer that includes an R / W that mediates non-contact communication with the SIM card 10-2 and performs issuance processing such as writing of individual data to the SIM card 10-2.

The SIM card 10-2 includes an IC chip 13-2, a contact terminal 11 connected to the IC chip 13-2, an antenna 12-2, a communication method determination unit 19, and the like. It is used by attaching to. The antenna 12-2 includes a winding coil connected to the RF unit 15 of the IC chip 13-2, a tuning capacitor connected to both ends of the winding coil, and the like. And conversion between analog signals and mediate non-contact communication between the external device and the IC chip 13-2. The communication method determination unit 19 is connected to the contact terminal 11, the RF unit 15, and the CPU 14-2, and whether the I / F during communication is a contact type or a non-contact type, that is, contact communication or non-contact communication. It is determined which communication method is used for communication with the external device. The communication method determination unit 19 determines whether the clock is supplied from the clock terminal of the contact terminal 11 or the clock output terminal of the RF unit 15 based on the difference in clock frequency, and outputs the determination result to the CPU 14-2. To do.
The CPU 14-2 implements a contact command control unit 141-2, a non-contact command control unit 142-2, and the like having the same functions as those in the first embodiment by executing the OS and application programs. Details of the function of each part will be described later with reference to FIG.

7 and 8 are diagrams showing data carrier operations and programs according to the present invention. FIG. 7 is an OS operation flowchart, and FIG. 8 is an explanatory diagram. Hereinafter, the processing of the CPU 14 (non-contact command control unit 142-2) will be mainly described.
In S300, the SIM card 10-2 is in a state of waiting for reception of a command transmitted from the issue processing devices 20A and 20B.
In S310, the SIM card 10-2 receives a command from the issue processing devices 20A and 20B via the contact terminal 11 or the antenna 12-2. The OS determines the communication method based on the output of the communication method determination unit 19 (S320). In the case of contact communication, the SIM card 10-2 performs the same processing as in the first embodiment (see FIGS. 4 and 5) (from S330 to S410).

  On the other hand, if it is determined in S320 that the communication is non-contact communication, the OS performs the same process as in the case of contact communication. That is, when the received non-contact command is not a contact application access command, the OS performs the same processing as the conventional one according to the non-contact command (S420, S400, S410, # 160 in FIG. 8). . If the received non-contact command is a contact application access command, the OS extracts the contact command from the data field bit of the contact application access command (S430) and writes it to the contact command response buffer 162 (S430). S440, # 120 in FIG. 8), the contact application is activated (S450, # 130 in FIG. 8). After the processing by the contact application (# 150, # 160 in FIG. 8) is completed, the processing result is read from the contact command response buffer 162 and transmitted to the issuance processing device 20B on the non-contact protocol (S460, S470). (S480), the process again waits for a command.

  Thus, according to the second embodiment, in addition to the same effects as the first embodiment, non-contact communication is performed between the issuance processing device 20B and the SIM card 10-2, whereby individual data of the contact application is transferred to the SIM card 10-. It is possible to write to 2 and issue a contact application. Therefore, the individual data of the contact application is performed by non-contact communication (106 Kbps), which has a higher communication speed than the contact communication (9600 bps), and the application issuing process can be accelerated.

  That is, when individual data write processing is performed, it is possible to arbitrarily select the issue processing devices 20A and 20B (communication method) without depending on the communication method supported by the application, and to perform the processing. Convenience can be improved. Further, by using either the issuance processing device 20A or the issuance processing device 20B, it is possible to write individual data for all applications installed in the SIM card 10-2, and there is no need to change the communication method. It has become possible to reduce the burden on equipment for processing and to speed up processing.

  The SIM cards 10 and 10-2 store the application program in the ROM 17 but may be stored in the nonvolatile memory 18, and if the program and data that need to be rewritten are stored in the nonvolatile memory 18, It is not limited whether other programs and data are stored in the ROM 17 or the nonvolatile memory 18.

  The SIM cards 10 and 10-2 process the commands transmitted from the issue processing devices 20A and 20B in the issue process, but the issued SIM cards 10 and 10-2 in which individual data is written are external The same processing may be performed on the command transmitted from the apparatus. For example, when the external device writes update data to the SIM cards 10 and 10-2, when the communication speed is important and the processing is speeded up, when the contact communication means such as the contact terminal 11 cannot be used. The characteristics of the communication system, such as writing by non-contact communication, placing importance on stable communication such as stable power supply, and writing by contact communication when contact communication means such as the antenna 12-2 cannot be used, The communication method can be selected on the external device side according to the situation and the like, and the convenience can be improved.

  The transmission protocol to which the SIM cards 10 and 10-2 comply is not limited to the contact transmission protocol and the contact transmission protocol shown in FIGS. 2 and 3, for example, in the information field as shown in FIG. A contact transmission protocol command storing a contact transmission protocol command, or a non-contact transmission protocol command storing a contact transmission protocol command in the information field as shown in FIG. 9B may be used. If a processing request corresponding to another communication method can be included in the processing request of one communication method, the communication is not limited.

  The SIM cards 10 and 10-2 perform communication using two different communication methods, contact communication and non-contact communication. However, the communication method is not limited to this, and a plurality of installed applications and a plurality of types of processing requests ( It is only necessary to use a plurality of communication methods corresponding to the (command) specification.
