Description

  The present invention relates to, for example, a portable electronic device that performs issue processing for recording issue information in a non-volatile memory in a contactless IC card having a wireless communication function, a processing device for a portable electronic device, and a portable electronic device. The present invention relates to a processing system and a processing method for a portable electronic device.

  Conventionally, an IC card as a portable electronic device defines a key file, a data file, and the like necessary for the purpose and use of the IC card in a nonvolatile memory inside the IC card, and further stores data in those files. It becomes usable by writing. In particular, the process of writing data to the IC card in the initial state according to the above processing procedure is called an IC card issuance process.

  The IC card incorporates an IC chip having a CPU, ROM, RAM, nonvolatile memory and the like. A control program for processing an external command is recorded in a ROM or the like in the manufacturing stage of the IC card in an initial state in which issuance information is not written in the nonvolatile memory. In the IC card in such an initial state, a function for executing processing according to an issuing command such as a data write request from the issuing device in the issuing processing as described above is prepared in advance. For example, a function for executing an instruction for writing issue information to itself is prepared.

  In a conventional IC card, one file is usually defined by execution for one command or one unit of data is written, and the execution result is responded to each command. It is like that. For this reason, the conventional IC card issuance processing is performed by sending issuing commands to each IC card as many as the number of files and data necessary for issuing, and the IC card sequentially executing each issuing command. This is done by returning a response indicating the result to the issuing device. In particular, IC cards often handle important information such as financial information and personal information according to the purpose of use. For this reason, importance is attached to the reliability and security of the data recorded in the IC card. For this reason, the IC card performs sequential processing in which processing is performed in response to the next command after the processing of the given command is completely completed.

  The IC card uses a nonvolatile memory such as an EEPROM or a flash memory as a data storage element. These memory elements have a disadvantage that it takes several mS to several hundred mS to write data once. When performing the IC card issuance procedure as described above, an issuance command such as a data write command given to the IC card is generally executed by the above-described sequential communication method. For this reason, the issuance process is performed by repeatedly writing data to the nonvolatile memory in the IC card.

Furthermore, in recent years, IC cards have been used in various fields. For this reason, the IC card has become multifunctional, and one IC card has various functions. For that purpose, many file definitions and data must be written in one IC card in the issuing procedure. However, since the issuing instruction is executed by the sequential method as described above, there is a problem that it takes a few minutes to issue one IC card.

Next, a configuration example of the non-contact type IC card C will be described.
FIG. 4 is a block diagram showing a configuration example of the non-contact type IC card C. As shown in FIG.
As shown in FIG. 4, the non-contact type IC card C includes a CPU (Central Processing Unit) 41, a ROM 43, a RAM 42, a nonvolatile memory 44, a transmission / reception circuit 45, and an antenna 46. Each unit such as the CPU 41, ROM 43, RAM 42, nonvolatile memory 44, transmission / reception circuit 45, and power generation unit 47 is configured by an IC chip, and is embedded in the casing of the non-contact IC card C.

  The CPU 41 functions as processing means and controls the entire non-contact type IC card. For example, the CPU 41 executes various data processing in accordance with commands from the reader / writer 12. The ROM 43 functions as a program memory, and is composed of a non-rewritable nonvolatile memory such as a mask ROM, for example. The ROM 43 stores a control program and data for controlling the operation of the non-contact IC card.

  For example, the process for the command from the reader / writer 12 is realized by the CPU 41 executing various control programs stored in the ROM 43. That is, the operation of the non-contact type IC card C in response to various external commands such as the reader / writer 12 is realized by each control program corresponding to each command stored in the ROM 43.

  The RAM 42 is a working memory that functions as storage means. The RAM 42 is composed of a rewritable volatile memory. The RAM 42 is composed of a memory element capable of writing high-speed data that operates with the electric power supplied from the power generation unit 47. The RAM 42 is used as a buffer memory that temporarily stores, for example, communication data with the outside and data for work in various processes executed by the CPU 41. In the present embodiment, the RAM 42 holds commands received from the reader / writer 12 or data to be written to the nonvolatile memory 44.

  The non-volatile memory 44 functions as a rewritable non-volatile data memory, and is composed of, for example, a non-volatile memory with rewritable storage contents such as an EEPROM or a flash memory. The non-volatile memory 44 stores (stores) various data as operation data according to the purpose and use of the contactless IC card. For example, when the contactless IC card is used as a credit card, the non-volatile memory 44 stores credit information such as personal information of the holder, financial information such as a card issuing company, card identification information, and expiration date information. It is recorded as data for use. Further, data is written into the nonvolatile memory 44 by the power supplied from the power generation unit 47. In the present embodiment, data held in the RAM 42 is written in the nonvolatile memory 44 under the control of the CPU 41.

  The transmission / reception circuit 45 performs data communication with an external device such as the reader / writer 12 via the antenna 46. The transmission / reception circuit 45 includes, for example, a modulation circuit, a demodulation circuit, a transmission circuit, and a transmission / reception circuit. The antenna 46 transmits and receives radio waves. The antenna 46 is embedded in the housing of the non-contact IC card C, for example, and is connected to an IC chip having functions such as the CPU 41, ROM 43, RAM 42, non-volatile memory 44, transmission / reception circuit 45, and power generation unit 47. Has been.

  The transmission / reception circuit 45 and the antenna 46 function as transmission means, reception means, or communication means, and realize data transmission / reception with the reader / writer 12. The transmission / reception circuit 45 and the antenna 46 also function as means for receiving radio waves used as power from an external device. For example, a command transmitted by radio waves from the reader / writer 12 is received by the antenna 46 and supplied to the transmission / reception circuit 45 as a reception signal. The transmission / reception circuit 45 demodulates the reception signal supplied from the antenna 46 and supplies it to the CPU 41. The transmission data generated in the non-contact type IC card C is modulated by the transmission / reception circuit 45 and transmitted to the outside through the antenna 46.

  The power generation unit 47 functions as a power generation unit, and generates operating power from radio waves received by the antenna 46. The power generation unit 47 supplies operating power generated from the radio wave received by the antenna 46 to each unit in the non-contact type IC card C.

Next, a processing example of issuing processing by the issuing system configured as described above will be described.
The non-contact type IC card C receives various issuing commands as commands from the reader / writer 12 side, and the non-contact type IC card C itself executes processing according to the received issuing commands. . Normally, a non-contact type IC card executes processing for a command received from an external device, and returns the processing result as a response. For this reason, in the conventional system, the reader / writer 12 transmits a next command after receiving a response to the effect that the processing in the non-contact type IC card is completed with respect to the transmitted command.

  On the other hand, in the present embodiment, each non-contact type IC card accumulates the command received from the reader / writer 12 or the processing data included in the command in the RAM 42 and sends a response indicating the completion of reception to the reader / writer 12. Send back. When the reader / writer 12 receives a response indicating completion of reception of the transmitted command, the reader / writer 12 transmits the next command to the non-contact type IC card C. As a result, the reader / writer 12 can sequentially transmit commands each time it receives a response indicating that a command has been received from the non-contact IC card. For this reason, the communication process between the reader / writer 12 and the non-contact type IC card can be completed in a short time.

Hereinafter, first, second, and third processing examples will be described as issuing processing by the IC card issuing system.
First, a first processing example of the issuing process will be described.
FIG. 5 explains a first processing example of the issuing process in the IC card issuing system.
First, the transport path 15 transports the non-contact type IC card C in an initial state in which issuance information is not written in the nonvolatile memory 44 at a predetermined interval. The non-contact IC card C in the initial state is first transported into the communication range 12a of the reader / writer 12 by the transport path 15, and then transported to the communication range 14a of the power supply device 14. ing.

  When the reader / writer 12 is not in a communication state with a specific non-contact type IC card C, the reader / writer 12 transmits power radio waves for starting communication to the non-contact type IC card C conveyed within the communication range 12a. The transmission is performed by the antenna 35 and the transmission / reception unit 34 (step S11). This radio wave supplies power for operating (starting up) the non-contact type IC card C to the non-contact type IC card C and requests a response indicating that communication is possible.

  The control unit 31 of the reader / writer 12 that is transmitting such electric power radio waves is waiting for a response from the non-contact IC card C (step S12). When a response indicating that communication is possible is received from the non-contact type IC card C in this state, the control unit 31 of the reader / writer 12 starts communication with the non-contact type IC card C (step S13).

Further, the non-contact type IC card C conveyed within the communication range 12a receives the electric wave for power from the reader / writer 12 by the antenna 46 (step S31). The radio signal received by the antenna 46 is supplied to the power generation unit 47. The power generation unit 47 generates power from the radio wave received by the antenna 46 and supplies the generated power to each unit in the non-contact type IC card C. As a result, the non-contact IC card C is activated by the power generated by the power generation unit 47 (step S32).
The CPU 41, to which the power generated by the power generation unit 47 is supplied, performs an initial operation of each unit and transmits a response indicating that communication is possible to the reader / writer 12 (step S33).

  The reader / writer 12 and the non-contact type IC card C can communicate with each other through the above processing. The reader / writer 12 and the non-contact type IC card C that are in a communicable state perform communication processing for transmitting and receiving an instruction (command) and a response (response) related to the issuance processing of the non-contact type IC card C. In this communication process, an issuance command transmission / reception process for supplying a command group for issuing to the non-contact type IC card C from the reader / writer 12 to the non-contact type IC card C and an issue start from the reader / writer 12 are started. Issuance start processing is performed to cause the non-contact type IC card C to execute each command of the issuing command group in response to the request.

  In the transmission / reception process for supplying the issuing instruction group to the non-contact type IC card C, the control unit 31 of the reader / writer 12 issues the issuing instruction group (here, Issue commands 1 to n) are sequentially transmitted to the non-contact IC card C by the antenna 35 and the transmission / reception unit 34.

  That is, when a response indicating that communication is possible is received from the non-contact IC card C conveyed within the communication range 12a, the control unit 31 of the reader / writer 12 first uses the transmission / reception unit 34 and the antenna 35. The issuing instruction 1 is transmitted to the non-contact type IC card C (step S14). The control unit 31 of the reader / writer 12 that has transmitted the issuing command 1 waits for a response from the non-contact IC card C to the issuing command 1 (step S15).

  When the reader / writer 12 transmits a radio wave as the issuing command 1, the non-contact IC card C receives the issuing command 1 by the antenna 46 (step S34). The radio signal received by the antenna 46 is supplied to the transmission / reception circuit 45 and the power generation unit 47. The power generation unit 47 generates power from the radio wave received by the antenna 46. The non-contact type IC card C is operated by the power generated by the power generation unit 47.

  The transmission / reception circuit 45 demodulates the radio signal received by the antenna 46 and supplies the demodulated signal (data) to the CPU 41. Here, the command as the issuing instruction 1 transmitted as a radio wave by the reader / writer 12 is demodulated by the transmission / reception circuit 45 and supplied to the CPU 41. The CPU 41 to which the command as data demodulated by the transmission / reception circuit 45 is supplied performs a process of storing the command supplied from the transmission / reception circuit 45 in the RAM 42 (step S35).

  When the process of storing the issuing command 1 received by the antenna 46 in the RAM 42 is completed, the CPU 41 sends a response 1 indicating whether or not the receiving of the issuing command 1 from the reader / writer 12 has been normally completed. The transmission / reception circuit 45 and the antenna 46 transmit the radio wave to the reader / writer 12 as a radio wave (step S36). For example, when the issuance command 1 received by the antenna 46 is normally stored in the RAM 42, the CPU 41 sends a response 1 indicating that reception of the issuance command 1 from the reader / writer 12 has been completed normally to the reader / writer. 12 to send. If the issuing command 1 received by the antenna 46 cannot be normally stored in the RAM 42, the CPU 41 responds with a signal indicating that an error has occurred in receiving the issuing command 1 from the reader / writer 12. 1 is transmitted to the reader / writer 12.

  A response 1 to the issuing command 1 transmitted from the non-contact type IC card C is received by the antenna 35 of the reader / writer 12 (step S16). The radio wave signal received by the antenna 35 of the reader / writer 12 is demodulated by the transmitter / receiver 34 and supplied to the controller 31. The control unit 31 determines whether or not the issuing command 1 has been normally received by the non-contact type IC card C based on the response 1 from the non-contact type IC card C received by the antenna 35 and the transmission / reception unit 34. (Step S17). When it is determined that the non-contact type IC card C has not normally received the issuing instruction 1 (NO in step S17), the control unit 31 performs the issuing process for the non-contact type IC card C. It is assumed that an error has occurred, and the issuing process for the contactless IC card C is terminated.

  Further, when it is determined that the non-contact IC card C has normally received the issuing instruction 1 by the above determination (step S17, YES), the control unit 31 sends the next issuing instruction 2 to the non-contact Processing to transmit to the IC card C is performed. In this case, the reader / writer 12 performs the same processing as in steps S14 to S17 for the issuing instruction 2. On the other hand, the non-contact type IC card C performs the same process as in steps S34 to S36.

  Such transmission / reception processing of each issuing instruction is sequentially executed for all issuing instructions 1 to n. That is, the reader / writer 12 and the non-contact type IC card C sequentially perform transmission / reception processing for all issuing commands 1 to n. As a result, the issuing instruction group (issuing instructions 1 to n) is stored in the RAM 42 of the non-contact IC card C.

  In the reader / writer 12, all of the issuing instructions 1 to n are normally not received by receiving a response that the non-contact IC card C has received the last issuing instruction (issuing instruction n) normally. The contact IC card C is determined to have been received. When it is confirmed that the non-contact type IC card C has normally received all the issuance instructions by the transmission / reception processing of the respective issuance instructions as described above, the control unit 31 of the reader / writer 12 An issuance start command requesting execution of each issuance command is transmitted to the card C (step S18).

  When the issue start command is transmitted from the reader / writer 12, the contactless IC card C receives the issue start command through the antenna 46 and the transmission / reception circuit 45 (step S37). When the issue start command is received, the CPU 41 transmits a response indicating that the issue start command has been received to the reader / writer 12 (step S38).

  The response transmitted from the non-contact type IC card C is received by the antenna 35 and the transmission / reception unit 34 of the reader / writer 12 (step S19). When receiving a response indicating that the issuing start command has been received, the control unit 31 of the reader / writer 12 ends the communication process for the non-contact IC card C.

  When the issue start command is received, the CPU 41 of the non-contact IC card C transmits the response as described above to the reader / writer 12 and executes the issue commands 1 to n stored in the RAM 42. (Step S39). At this time, the non-contact type IC card C is continuously operated by radio waves from the reader / writer 12 or the power supply device 14. That is, even if the non-contact type IC card C is out of the communication range 12a of the reader / writer 12 while executing the instructions 1 to n, the power supply device 14 in the communication range 14a It operates by generating electric power from the transmitted radio waves.

  When the issuing instructions 1 to n stored in the RAM 42 in step S39 are completed, the contactless IC card C has executed all issuing instructions. For example, when the reader / writer 12 requests the non-contact IC card C to write various issuance information in the nonvolatile memory 44 by the issuing instructions 1 to n, the non-contact IC card C uses the RAM 42. The issuing instructions 1 to n stored in are sequentially executed. As a result, the issuance information requested to be written by the issuing instructions 1 to n is written in the non-volatile memory 44 of the non-contact type IC card C, and the non-contact type IC card C is already issued. .

  Further, as described above, the non-contact type IC card C is transported by the transport path 15 in the issuing process. The communication range 12a and the communication range 14a are, as shown in FIG. 1, between the time when the non-contact type IC card C on the transport path 15 enters the communication range 12a and the time when the communication range 14a leaves the communication range 14a. It is set to be in any communication range.

  The communication range 12a is set so that at least communication processing (the steps S11 to S19 and S31 to 38) between the non-contact IC card C transported along the transport path 15 and the reader / writer 12 is completed. The communication range 14a is set so that at least all of the issuing processes (step S38) corresponding to a plurality of issuing commands stored in the RAM 42 in the non-contact IC card are completed.

  For this reason, the communication range 12a and the communication range 14a include the conveyance speed of the non-contact type IC card C by the conveyance path 15, the processing time of communication processing between the reader / writer 12 and the non-contact type IC card C, and the non-contact type IC card. C is set according to the processing time of the processing for executing all the instructions stored in the RAM.

  In step S39, while the issuing instructions 1 to n stored in the RAM 42 are being executed, the contactless IC card C receives radio waves from the power supply device 14 in order to generate operating power. However, communication with an external device is not performed.

  As described above, in the first processing example, the reader / writer 12 sequentially transmits a plurality of issuing commands to the non-contact type IC card C within the communication range 12a. The issuing instructions 1 to n are temporarily stored in the RAM 42 and a response is returned to the reader / writer 12. Further, the non-contact type IC card in which each issue command is stored in the RAM 42 operates by receiving power supply from the power supply device while retaining the storage contents of the RAM 42, and each issue command stored in the RAM 42. 1 to n are sequentially executed. Thereby, since the process of storing data in the RAM in the non-contact type IC card can be performed at high speed, the communication process between the reader / writer 12 and the non-contact type IC card C can be completed in a short time.

  A plurality of issuing commands stored in the RAM are executed in a non-contact type IC card that operates with power supplied from a power supply device different from the reader / writer. As a result, in the entire system, even when a non-contact IC card executes a large number of issuing instructions, a process that requires processing time such as data writing processing to the non-volatile memory 44 is performed. Even when the card is executed, a sufficient time can be secured for the process executed by the non-contact IC card. In addition, since the communication process between one reader / writer 12 and each non-contact type IC card is completed in a short time, the entire system can efficiently issue a large number of non-contact type IC cards.

Next, a second processing example of the issuing process will be described.
FIG. 6 illustrates a second processing example of the issuing process in the IC card issuing system.
In this second processing example, it is assumed that the issuing instructions 1 to n are requests for writing data such as issuing information to the nonvolatile memory 44. In the second processing example, the non-contact IC card C accumulates data to be written in the nonvolatile memory 44 supplied as the issuing instructions 1 to n from the reader / writer 12 in the RAM 42, and communication processing with the reader / writer 12 is performed. After completion, a process of writing the data accumulated in the RAM 42 to the nonvolatile memory 44 is performed. In the flowchart of FIG. 6 described as the second processing example, the same processing steps as the processing steps in the flowchart of FIG. The detailed explanation is omitted.

  The reader / writer 12 and the non-contact type IC card C can communicate with each other by the same processing as in steps S11 to S13 and S31 to 33. In this state, the reader / writer 12 sequentially transmits issuance instructions 1 to n for requesting writing of data to the nonvolatile memory 44 to the non-contact type IC card C by the same process as in steps S14 to S17.

  On the other hand, in the non-contact type IC card C, the issuing command 1 transmitted as a radio wave from the reader / writer 12 is received by the antenna 46 (step S34). The radio signal received by the antenna 46 is supplied to the transmission / reception circuit 45 and the power generation unit 47. The power generation unit 47 generates power from the radio wave received by the antenna 46 and supplies the generated power to each unit in the non-contact IC card C. The transmission / reception circuit 45 demodulates the radio signal received by the antenna 46 and supplies the demodulated signal (data) to the CPU 41. Here, the command as the issuing instruction 1 transmitted as a radio wave by the reader / writer 12 is demodulated by the transmission / reception circuit 45 and supplied to the CPU 41.

  The CPU 41 to which the issuing instruction 1 as data demodulated by the transmission / reception circuit 45 is supplied analyzes the issuing instruction 1 and determines data to be written in the nonvolatile memory 44. Thus, when the data to be written to the nonvolatile memory 44 is determined based on the issuing instruction 1, the CPU 41 stores the data to be written to the nonvolatile memory 44 in the RAM 42 (step S55).

  When data to be written to the nonvolatile memory 44 is stored in the RAM 42 based on the issuing command 1, the CPU 41 sends a response 1 indicating that the receiving of the issuing command 1 from the reader / writer 12 has been normally completed. The transmission / reception circuit 45 and the antenna 46 transmit the radio wave to the reader / writer 12 as a radio wave (step S36).

  The same processing as in steps S14 to S17, S34, S55, and S36 is executed for each of the issuing instructions 1 to n. Therefore, the RAM 42 of the non-contact type IC card C stores all data to be written in the nonvolatile memory 44 based on the issuing commands 1 to n sequentially transmitted from the reader / writer 12.

  When the reader / writer 12 confirms that all the issuing instructions 1 to n have been normally received by the non-contact type IC card C, the issuance start instruction is transmitted to the non-contact type IC card C. (Step S18). In this second processing example, the issue start command transmitted from the reader / writer 12 to the non-contact type IC card C in step S18 functions as a command for requesting processing for writing the data stored in the RAM 42 into the nonvolatile memory 44. To do.

  When the issue start command is transmitted from the reader / writer 12, the contactless IC card C receives the issue start command through the antenna 46 and the transmission / reception circuit 45 (step S37). When the issue start command is received, the CPU 41 transmits a response indicating that the issue start command has been received to the reader / writer 12 (step S38).

  The response transmitted from the non-contact type IC card C is received by the antenna 35 and the transmission / reception unit 34 of the reader / writer 12 (step S19). When receiving a response indicating that the issuing start command has been received, the control unit 31 of the reader / writer 12 ends the communication process for the non-contact IC card C.

  When the issuing start command is received, the CPU 41 of the non-contact IC card C transmits a response as described above to the reader / writer 12 and writes the data accumulated in the RAM 42 to the nonvolatile memory 44. Is performed (step S59). At this time, the non-contact type IC card C is continuously operated by radio waves from the reader / writer 12 or the power supply device 14. That is, even if the non-contact type IC card C is out of the communication range 12a of the reader / writer 12 while executing the instructions 1 to n, the power supply device 14 in the communication range 14a It operates by generating electric power from the transmitted radio waves.

  When all the data stored in the RAM 42 is written in the nonvolatile memory 44 in step S39, the non-contact IC card C has completed the issuing process based on the issuing instructions 1 to n received from the reader / writer 12. Become. In step S39, while the issuing instructions 1 to n stored in the RAM 42 are being executed, the contactless IC card C receives radio waves from the power supply device 14 in order to generate operating power. However, communication with an external device is not performed.

  As described above, in the second processing example, the reader / writer 12 sequentially transmits a plurality of issuing commands to the non-contact type IC card C within the communication range 12a. The instructions 1 to n are sequentially analyzed, and data to be written to the nonvolatile memory 44 is temporarily stored in the RAM 42 based on each issuing instruction, and a response to each issuing instruction is returned to the reader / writer 12. Further, the non-contact type IC card that has received all the issuing commands from the reader / writer 12 operates by receiving power supply from the power supply device 14 while holding the data to be written in the nonvolatile memory 44 in the RAM 42. Then, the data stored in the RAM 42 is written into the nonvolatile memory 44.

  Thereby, the communication process between the reader / writer 12 and the non-contact type IC card C can be completed in a short time. This is because the process of storing data in the RAM 42 in the non-contact IC card C is faster than the process of writing data in the nonvolatile memory 44. As a result, in the IC card issuing system, the issuing process for a large amount of non-contact type IC card C can be executed efficiently.

  Further, the data stored in the RAM 42 is written in the nonvolatile memory 44 in the non-contact type IC card C that operates by the power supplied from the power supply device 14 different from the reader / writer 12. As a result, as a whole system, even when a large amount of data is written to the nonvolatile memory 44 by a large number of issuing instructions, the non-contact IC card C writes data to the nonvolatile memory 44. Sufficient time can be secured. In addition, since the communication process between one reader / writer 12 and each non-contact type IC card C is completed in a short time, the entire system can efficiently issue a large number of non-contact type IC cards C. it can.

Next, a third processing example of the issuing process will be described.
FIG. 7 explains a third processing example of the issuing process in the IC card issuing system.
In this third processing example, the issuance command group is accumulated in the RAM 42 by the same processing as in the first processing example, and a command to deselect the non-contact IC card is received from the reader / writer 12. Based on the above, the non-contact type IC card shifts to a mode in which communication with an external device is cut off, and in this mode, the issuing command stored in the RAM 42 is executed. In the flowchart shown in FIG. 7, processing steps similar to those in FIG. Accordingly, in the description of the third processing example, detailed description of the same processing as in the first processing example is omitted.

  That is, the reader / writer 12 and the non-contact type IC card C can communicate with each other by the same processing as in steps S11 to S13 and S31 to 33. In this state, the reader / writer 12 sequentially transmits the issuing instructions 1 to n to the non-contact type IC card C by the same process as in steps S14 to S17. On the other hand, in the non-contact type IC card C, the issuing instructions 1 to n sequentially transmitted as radio waves from the reader / writer 12 are sequentially stored in the RAM 42 by the same processing as the above steps S34 to S36.

  When the reader / writer 12 confirms that all the issuing instructions 1 to n have been normally received by the non-contact IC card C, the reader / writer 12 receives the non-contact IC card C from the non-contact IC card C. Is transmitted as a communication partner (DESELECT command) (step S68). This DESELECT command is a command for requesting the non-contact type IC card to shift to a state in which communication with the outside is cut off. For example, in ISO / IEC14443 Type-B, an HLTB command is defined as a command (DESELECT command) for deselecting an IC card.

  When the DESELECT command is transmitted from the reader / writer 12, the contactless IC card C receives the DESELECT command through the antenna 46 and the transmission / reception circuit 45 (step S77). When the DESELECT command is received, the CPU 41 transmits a response indicating that the DESELECT command has been received to the reader / writer 12 (step S78), and shifts to a non-communication state as an operation mode for disconnecting communication with the outside. To do. For example, ISO / IEC 14443 Type-B stipulates that an IC card that has received the HLTB command shifts to a non-communication state as an operation mode that disconnects communication with the outside called HALT State.

The reader / writer 12 ends the communication process with the non-contact type IC card C based on the response indicating that the DESELECT command has been received (step S69). On the other hand, in the non-contact IC card C that has shifted to the non-communication state in response to the DESELECT command, the issuing commands 1 to n stored in the RAM 42 are executed (step S79). At this time, the non-contact type IC card C is continuously operated by radio waves from the power supply device 14. In other words, the non-contact type IC card C operates by generating electric power from radio waves transmitted from the power supply device 14 in the communication range 14a.
When all the issuing instructions 1 to n stored in the RAM 42 are executed in step S79, the non-contact IC card C has completed the issuing process based on the issuing instructions 1 to n received from the reader / writer 12. It becomes.

  As described above, in the third processing example, the reader / writer 12 sequentially transmits a plurality of issuing commands to the non-contact type IC card C within the communication range 12a. The commands 1 to n are sequentially stored in the RAM 42 and a response indicating that each issuing command has been received is returned to the reader / writer 12. Further, when the reader / writer 12 transmits all the issuance commands to be executed by the non-contact type IC card, the reader / writer 12 transmits a DESELECT command for ending the communication with the non-contact type IC card C. The contactless IC card that has received the DESELECT command shifts to an operation mode in which communication with the outside is interrupted while retaining the stored contents of the RAM 42, and operates by receiving power supply from the power supply device 14. The issuing instructions 1 to n stored in the RAM 42 are executed.

  For example, in ISO / IEC14443 Type-B, an HLTB command for setting an IC card in a non-selected state is defined. In an IC card compliant with ISO / IEC14443 Type-B, when an HLTB command is received, the IC card shifts to a HALT state as an operation mode in which communication with the outside is interrupted. Therefore, when the third processing example is applied to ISO / IEC14443 Type-B, the non-contact IC card in which the issuing instruction group is stored in the RAM 42 by the same processing as the first processing example is transmitted from the reader / writer 12 to the HLTB command. Are issued, the issuing instructions stored in the RAM 42 are sequentially executed.

  According to the third processing example as described above, the communication processing between the reader / writer 12 and the non-contact type IC card C can be completed in a short time. As a result, in the IC card issuing system, the issuing process for a large amount of non-contact type IC card C can be executed efficiently.

  The plurality of issuing commands stored in the RAM 42 are executed in the non-contact type IC card C that is operated by the power supplied from the power supply device 14 different from the reader / writer 12. As a result, as a whole system, even when a large amount of data is written to the nonvolatile memory 44 by a large number of issuing instructions, the non-contact IC card C has sufficient time to execute each issuing instruction. Can be secured. In addition, since the communication process between one reader / writer 12 and each non-contact type IC card C is completed in a short time, the entire system can efficiently issue a large number of non-contact type IC cards C. it can.

As described above, in this embodiment, in the non-contact type IC card, each time a command sequentially transmitted from the reader / writer is received, each command is stored in the RAM 42 and a response is returned, and communication processing with the reader / writer is performed. After completion, that is, after reception of all instructions transmitted from the reader / writer is completed, the apparatus operates by receiving power from the power supply device 14 and executes the instructions stored in the RAM 42. .
As a result, the time required for communication processing between the reader / writer and the non-contact type IC card can be shortened, and issue processing for a large amount of non-contact type IC cards by one reader / writer can be efficiently performed.
