Description

  The present invention relates to a communication device that communicates with a non-contact communication medium such as a non-contact IC card, and more particularly to a communication device that identifies a plurality of non-contact communication media.

  In recent years, contactless IC cards have been widely used in place of magnetic cards in fields such as railways, buses, leisure, and distribution. Such a card is generally used as a single card, but may be used in a state where two cards are stacked. For example, when you pass through a section of a commuter pass (card “1”) and get off at a station other than the section, read the commuter pass and another card (card “2”) in order to clear the transit section. May be tricked into equipment. At this time, the reader that has captured the two cards settles the charge for the transit section with the card superimposed on the commuter pass. This improves the convenience for the user. Moreover, such a card | curd is utilized also for distribution, such as shopping in a store, besides the utilization as a boarding ticket.

  Further, as a usage form of the non-contact type IC card, there is a case where the card is used while being put in a wallet, a bag or the like, in addition to directly placing the card in the reading device as described above. When the card is used in a wallet or a bag, since cards issued by different companies may be mixed, it is necessary to distinguish a card of a desired company and other cards. Further, in payments such as distribution sales, it is necessary to ask the user to determine which card is used for payment processing when a plurality of cards with payment applications are installed.

  As a method for identifying such multiple cards, it is proposed to first capture the first card, perform mutual authentication, and then capture the second card by performing the card capture process again. (For example, refer to Patent Document 1). Similarly, it has also been proposed to capture the second card by performing the capture process again while capturing the first card and performing mutual authentication.

  FIG. 10 is a diagram showing internal information of a non-contact communication medium such as a conventional non-contact IC card. This non-contact communication medium is equipped with one system having a unique ID. FIG. 11 is a diagram showing an outline of the operation of a conventional communication apparatus for identifying a plurality of (here, two) cards (non-contact type IC cards) on which one system is mounted as described above.

  The communication device transmits a capture command to the cards “1, 2” in the unauthenticated mode, and sends an authentication command “1” when there is a response from the card “1”. When there is a response of the authentication command “1”, the card “1” is in the authentication mode, and the card “1” does not respond to the capture command because the operation mode is the authentication mode. For this reason, the card “2” responds to the capture command from the communication device. When there is a response from the card “2”, the communication device sends an authentication command “2”. At this time, the card “1” responds, and the card “1” responds to the capture command with the operation mode being the authentication mode. do not do. Then, the card “2” responds to the capture command from the communication device.

  Recently, cards equipped with a plurality of systems have been widely used. FIG. 12 is a diagram showing internal information of a non-contact communication medium equipped with such a plurality of systems. This non-contact communication medium has a unique ID for each of a plurality of systems “1, 2,.

  There are two types of commands for capturing a non-contact type IC card: a capture command to which all systems respond, and a capture command to which only a designated system responds (system identifier designation capture command). There is also a command for obtaining an identification ID list of the system mounted on the card.

  Even in a card equipped with a plurality of systems, only one system can operate simultaneously. For this reason, when a capture command to which all systems respond is received, the system with the highest priority responds. Also, a card equipped with a plurality of systems is given a unique ID for each system as described above, and the system to be operated can be selected by specifying the unique ID. . Furthermore, since mutual authentication is performed on the target system, even if the command that responds to all systems is received even if the operating mode of the second highest priority system is being authenticated or has been changed to authenticated. The card switches the operating system, and the system with the highest priority responds in an unauthenticated state.

  FIG. 13 is a diagram showing the operation of a conventional communication apparatus for identifying a plurality of cards (multi-application compatible non-contact IC cards) equipped with a plurality of systems having such unique IDs. Here, a case where the operation priority is higher in the order of the systems “1 to n” is shown.

  When the communication device transmits a capture command specifying the system and the card “1” responds, the communication device transmits an authentication command “1” for the system “2” that is the target system of the card “1”. As a result, the system “2” of the card “1” is in the authenticating mode, and the other systems of the card “1” remain unauthenticated. When the communication device transmits the next capture command, all the systems “1 to n” including the system “2” of the card “1” are unauthenticated. The system “2” of the card “1” is unauthenticated because the system “1” having a high operation priority reacts to the capture command for capturing all cards, and the system is switched. This is because “2” transits to the unauthenticated mode, and the system “1” responds to the capture command.

When all the systems of the card “1” are unauthenticated, the communication device transmits a capture command designated by the system, and when the card “1” responds, the communication device responds to the authentication command “1” for the system “2”. Send. As a result, when the system “2” of the card “1” is in the authentication mode and the communication device retransmits the authentication command “1” for the system “2”, the system “2” of the card “1” is in the authentication mode. It becomes. When the communication device transmits the next capture command, the system “2” of the card “1” is again unauthenticated. This is because, in the capture command for capturing all cards, the system “1” having a high operation priority reacts as described above, and the system “1” responds to the capture command.
Japanese Patent Laid-Open No. 2000-276561 (FIG. 2)

  In the conventional communication apparatus having the above configuration, as shown in FIG. 13, when trying to identify a plurality of non-contact type IC cards equipped with a plurality of systems, for example, for a system having the second highest operation priority. When the operation mode is changed, the system having the highest operation priority operates and responds to the capture command with respect to the capture command to which all non-contact IC cards transmitted next respond. For this reason, the same non-contact type IC card may be captured, and there is a problem that a plurality of non-contact type IC cards cannot be identified.

  The present invention has been made in view of these points, and is a non-contact communication medium equipped with a plurality of systems, and even when the operation priority of the target system is low, a plurality of non-contact communication An object of the present invention is to provide a communication apparatus capable of identifying a medium.

  In the present invention, in order to solve the above-described problem, when a plurality of applications having different operation priorities can be executed and the highest priority application is in the unauthenticated mode, the highest priority application is set in the authentication mode in response to a polling command. A communication device that communicates with a non-contact communication medium that does not respond to a polling command in some cases, and transmits the polling command to the surroundings and receives a response to the polling command from the non-contact communication medium. After detecting a communication medium and transitioning the highest priority application of the non-contact communication medium from the unauthenticated mode to the authentication mode, the polling command is transmitted to the surroundings during a set period, Response to other contactless communication media Control unit for detecting the other of the non-contact communication medium by al receiving communication apparatus having is provided.

  In the communication apparatus according to the present invention, the non-contact communication medium whose operation mode is changed does not respond to the polling command again. Therefore, the operation priority of the target system is low in the non-contact communication medium in which a plurality of systems are mounted. Even in this case, there is an advantage that a plurality of contactless communication media can be identified.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a communication apparatus according to an embodiment of the present invention. Here, an example is shown in which a payment apparatus that performs payment processing by communicating with a card is shown. This settlement apparatus 1 identifies a plurality of cards (non-contact IC cards) that are non-contact communication media equipped with a plurality of systems, and performs card settlement with a predetermined center.

  The settlement apparatus 1 is entirely controlled by a CPU (Central Processing Unit) 10, an RF module 11 that communicates with a card, a communication interface 12 that communicates with a center, and a volatile memory 13 for work of the CPU 10. And a non-volatile memory 14, an input unit 15, a display unit 16, a printer unit 17, and a power supply module 18 for supplying power to each unit.

  FIG. 2 is a diagram illustrating a configuration example of a card on which a plurality of systems are mounted. Here, two cards α and a card β are shown. The card α is loaded with a system A, a system B, and a system C each having an identification ID (identifier) and a unique ID, and the operation priorities are different. In the card β, a system B and a system C having an identification ID and a unique ID different from the identification ID and unique ID of the card α are mounted.

  When the settlement apparatus communicating with the card transmits a “capture command to which all systems respond” to the card α, the system A having the highest operation priority among the systems mounted on the card α responds. When the settlement apparatus transmits a “capture command to which all systems respond” to the card β, the system B having the highest operation priority among the systems mounted on the card β responds.

  Then, when the system A of the card α is in the state of mutual authentication, when the settlement apparatus transmits “capture command to which all systems respond” to the cards α and β, the system B mounted on the card β responds. . At this time, the card α does not respond to the capture command because the system A having the highest operation priority is already authenticated.

  Further, when the system A of the card α is in the state of mutual authentication, when the payment apparatus transmits “command specifying ID_B” to the card α, the system B responds and similarly transmits “command specifying ID_C”. System C then responds.

  FIG. 3 is a diagram showing a configuration example of the unique ID of the card. This unique ID is composed of information indicating the order in which the systems are mounted, that is, a portion indicating the number of the system mounted on the card, and manufacturing information such as a serial number indicating manufacture of the card. Then, the settlement apparatus controls the target card and system by designating this unique ID and transmitting a command.

  In other words, the card receives the unique ID included in the command transmitted from the payment device, and whether the card is specified by the data of the part indicating the manufacturing serial number of the card or other card is specified. to decide. Then, when self is specified, it is determined which system is to be operated with the data of the portion indicating the installed system.

  Here, the settlement apparatus 1 shown in FIG. 1 has an RF module (communication unit) 11 that transmits a polling command for capturing a card. When a polling response to the polling command is received, the settlement device 1 The CPU 10 is configured with transition means for transitioning the operation mode of the system having the highest operation priority of the system operating with the transmitted card. Then, after changing the operation mode, the CPU 10 transmits a polling command for capturing the card again during a set period (within a predetermined time) and receives a polling response, thereby receiving a plurality of cards. Recognize and process each recognized card individually.

  Further, when a polling response to the polling command is received by the CPU 10, an acquisition unit that acquires a list of identifiers of systems that operate on the card that has transmitted the polling response, and a target system in the acquired identifier list Determining means for determining whether or not the identifier exists, and the CPU 10 changes the operation mode of the system having the highest operation priority in the system operating with the card “2” determined to have the identifier, and thereafter A plurality of cards are recognized by transmitting a polling command for capturing the card during a set period and receiving a polling response, and it is determined that there is an identifier of the target system among the recognized cards. Process each card individually.

  In addition, when the CPU 10 determines that the system identifier is present, a confirmation unit is configured to confirm whether the target service is installed in the system, and the CPU 10 includes the service. Transition the operation mode of the system with the highest operation priority among the systems that operate with the confirmed card, and then send the polling command to capture the card again during the set period and receive the polling response A plurality of cards are recognized, and processing is individually performed on the cards that have been confirmed to be equipped with the target service among the recognized cards.

  When the CPU 10 confirms that the target service is installed, an authentication unit that performs mutual authentication for the service of the target system is configured, and the CPU 10 is a card that is mutually authenticated. By switching the operating mode of the system with the highest operating priority among the operating systems, and then sending a polling command to capture the card again during the set period and receiving a polling response, Recognize and process each of the recognized cards individually for the cards for which the target service is mutually authenticated.

In addition, the CPU 10 includes a reading unit that reads information on a target service when the mutual authentication is normally completed, and a determination unit that determines an operation based on the read information. shifts the operation mode of the internal operation with the highest priority system in the system that operates in the card, then it receives a transmission to poll response polling command to capture again card during set period A plurality of cards are recognized by the above, and processing is individually performed on the recognized cards among the recognized cards.

  4 and 5 are diagrams showing a communication sequence in the embodiment. Here, the flow of the operation in which the settlement apparatus 1 configured as shown in FIG. 1 identifies a plurality of cards “1” and cards “2” is shown.

  When the payment device 1 transmits a capture command (polling command) to which all cards respond, and there is a response (response) from the card “1”, the payment device 1 is connected to the card “1”. Send a list request command. When the list is transmitted from the card “1”, the settlement apparatus 1 determines whether a target system (here, system “2”) exists. If there is a target system, a confirmation command for the target service is transmitted, and if there is a response, it is confirmed whether there is a target service. If there is a target service, the authentication command “1” for the system “2” is transmitted, and if there is a response, the system “2” of the card “1” is being authenticated. If the card can be authenticated, an authentication command “2” for the system “2” is transmitted, and if there is a response, the card “1” is in an authenticated state. Subsequently, if authentication of the terminal to be settled is possible, an authentication command “1” for the system “1” is transmitted, and if there is a response, the system “1” of the card “1” is being authenticated, and the system “2” Unauthenticated.

  Next, when the settlement apparatus 1 transmits a capture command, the card “2” reacts and repeats the transmission of the capture command and the reception of the response within the set time or number of times. When the mutual authentication process for the system “2” is completed, the system “2” of the card “1” enters the authentication mode, and the settlement process for the system “2” of the card “1” is performed. Further, when the target system “2” does not have a target service, or when card authentication and terminal authentication cannot be performed, the settlement apparatus 1 transmits an authentication command “1” for the system “1”. If there is a response, the system “1” of the card “1” is being authenticated.

  Next, detailed operation of the above-described settlement apparatus will be described. 6 and 7 are diagrams showing a flow of communication control operation of the settlement apparatus according to the embodiment, showing an example in which one card is captured and settlement processing is performed.

  The settlement apparatus 1 displays the settlement amount input by the store clerk on the display unit 16 and, upon accepting the settlement start input, displays the settlement process start on the display unit 16 and tricks the customer into the predetermined part. Encourage you to. The settlement apparatus 1 transmits a capture command for responding to all systems to the card through the RF module 11 (S1). The card that has received this command responds to the system with the highest operation priority among the installed systems, and returns its own unique ID. When the settlement apparatus 1 receives the response (S2), if the card has already been captured (S3), the settlement apparatus 1 transmits a request command for acquiring the identification ID list of the system mounted on the card (S3). S4). If no response is received, it is determined whether or not the first card is being captured (S5), and if it is captured, it is determined whether or not the set period has passed (timeout) (S6). For example, the transmission of the capture command and the reception of the response are repeated.

  When a response is received in response to the above request command and the identification ID list of the system in which the card is mounted is returned (S7), the settlement apparatus 1 determines that the target system is included in the system identification ID list acquired by the reply. It is determined whether there is (S8). When there is no target system, the settlement apparatus 1 uses the unique ID acquired earlier to change the operation mode of the system having the highest operation priority in the captured card.

  Here, the system having the highest operation priority is described at the beginning of the system identification ID list of the card, and the system having the highest operation priority responds to the card that has received the capture command to which all systems respond. That is, the unique ID responding to the capture command to which all the systems respond is the unique ID of the system having the highest operation priority in the card. In addition, since the identification ID list of the system mounted on the card is listed in order from the highest operation priority, the unique ID of another system can be calculated from the order. Therefore, the unique ID of another system mounted on the card can be calculated from the unique ID and the identification ID list of the system mounted on the card.

  If the card is not a captured card (S20), the settlement apparatus 1 stores the unique ID of the card (S21), transmits a mutual authentication “1” command to the card (S22), and Change the operation mode of the system to “authenticating”. That is, the payment apparatus 1 uses the unique ID acquired by transmitting the capture command to which all the systems respond, and changes the operation mode of the system having the highest operation priority in the captured card. At this time, if no response is received for the transmission of the authentication “1” command (S23), the transmission is repeated a specified number of times (S24).

  The settlement apparatus 1 stores the acquired unique ID, and then transmits a capture command to which all the systems respond within the preset period. At this time, the settlement apparatus 1 displays the processing result as a “capture error” on the display unit 16 when it is not possible to capture one card equipped with the target system within the set period (S33). Prompts the user to try again, or terminates the process.

  Here, if the card is out of the power supply range as part of the operation of deceiving the user's card, the card is powered off and the card's operation mode is reset (unauthenticated mode) The Then, when the card is defeated again within the power supply range, the card responds to a capture command to which all the systems respond. Accordingly, the settlement apparatus 1 identifies whether the card has already been captured by comparing the stored unique ID with the received unique ID. If the card has already been captured as a result of the identification, the settlement apparatus 1 transmits a mutual authentication “1” command to shift the operation mode of the system of the captured card. Then, a capture command to which all the systems respond is transmitted to capture the target card again. The unique ID stored in the settlement apparatus 1 is cleared when the settlement apparatus 1 ends the processing for the card or starts the processing for the card.

  When there is a target system on the card captured by the payment apparatus 1, the payment apparatus 1 uses the unique ID acquired by the capture command to which all the systems respond and the system identification ID list to the captured card. A unique ID indicating the installed target system is calculated, and a command for confirming whether the target payment service exists in the target system is transmitted using the unique ID (S9).

  By receiving a response to the command transmission (S10), it is determined whether there is a target settlement service (S11). When there is no payment service, the payment apparatus 1 uses the unique ID acquired by the capture command to which all the systems respond, in order to change the operation mode of the system having the highest operation priority in the card. Send a “1” command. Then, the unique ID acquired by the capture command to which all the systems respond is stored, and the capture command to which all the systems respond is transmitted in order to capture the target card again. If there is a target payment service, the payment apparatus 1 uses the calculated unique ID to transmit an authentication “1” command for mutual authentication with the target service installed in the target system ( S12).

  By receiving a response to the transmission of the authentication “1” command (S13), it is determined whether the card has been authenticated (S14). If the authentication fails, the settlement apparatus 1 transmits the mutual authentication “1” command in order to shift the operation mode of the system having the highest operation priority using the acquired unique ID. Then, the unique ID acquired by the capture command to which all the systems respond is stored, and the capture command to which all the systems respond is transmitted in order to capture the target card again. When the authentication is successful, the settlement apparatus 1 stores the calculated unique ID and uses the acquired unique ID to change the operation mode of the system having the highest operation priority in the successfully authenticated card. The above mutual authentication “1” command is transmitted.

  Next, in order to determine whether another target card exists, a capture command to which all the above systems respond is transmitted, and an authentication “2” command is transmitted to perform mutual authentication with the target service in the same manner as described above. (S15). If a response is received for the transmission of the authentication “2” command (S16), it is determined whether the terminal can be authenticated (S17). The calculated unique ID of the obtained card is stored (S18). The stored unique ID is used when it is determined whether the card is out of the power supply range by the user and the operation mode is reset, and the card is again set in the power supply range. .

  When another target card is captured within the set period, the payment apparatus 1 detects a plurality of target cards (S19), and displays a message prompting the user to trick only the target card. To do. The user can receive this message and only trick the target card.

  If a card on which another target system is mounted cannot be captured within the set period, the settlement apparatus 1 performs the mutual authentication process again using the stored unique ID of the target card. That is, an authentication “1” command is transmitted to the target system (S25), and if a response is received (S26), an authentication “2” command is transmitted to the target system (S27). If a response is received (S28), the process proceeds to a settlement process.

  In the payment process, the card information is read, and the remaining amount obtained by subtracting the payment amount from the read remaining amount information, payment log data, and the like are written to the card. That is, a read command for the target service is transmitted (S29), and after receiving the response (S30), a write command for the target service is transmitted (S31). If a response is received (S32), the processing result is displayed.

  When the above series of payment processing ends normally, the payment apparatus 1 stores the processing history in the nonvolatile memory 14, prints a receipt on the printer unit 17, and displays the processing result on the display unit 16.

  The above-described control operation of the settlement apparatus 1 is an example in which only one card loaded with a target system or service is captured and the settlement process is performed. In the embodiment, the settlement apparatus 1 has a predetermined period. It is also possible to capture a plurality of cards on which the target system is mounted and process the captured cards individually.

  Next, a detailed operation of the settlement apparatus 1 that captures a plurality of cards and performs processing individually will be described with reference to FIGS. 6, 8, and 9. 8 and 9 are diagrams showing a flow of communication control operation of the settlement apparatus 1 in the embodiment.

  The operations in S51 to S60 and S66 in FIG. 8 are the same as the operations in S18 to S28 and S34 in FIG. 7, and thus redundant description is omitted. In S55, the card unique ID is stored as a non-target card. Then, the balance confirmation process starts after S60. At this time, a read command for the target service is transmitted (S61), and after receiving the response (S62), the unique ID and the balance are stored (S63).

  Then, it is determined whether all the stored target cards have been processed (S64). If the processing has been completed, it is confirmed whether the total balance is larger than the settlement amount (settlement amount ≦ balance total) (S65). If there is more, the card with the smallest balance in the stored information is targeted (S67) and the settlement process is started. At this time, a write command for the target service is transmitted (S68), and if a response to the command transmission is received (S69), deletion from the stored card information is performed (S70).

  Subsequently, it is determined whether or not the settlement is completed (S71). If the stored information is not yet completed (S72), the above settlement processing is continued. If the settlement is completed, the processing result is displayed. (S73), this process ends.

The operations in S74 to S78 in FIG. 9 are the same as the operations in S57 to S60 and S66 in FIG.
As described above, the settlement apparatus 1 first captures a plurality of target cards within a set period. Then, after the remaining amount is read from the captured target card and it is confirmed that the total amount is larger than the settlement amount, the settlement process can be continued until the settlement amount is reached in order from the card with the smallest remaining amount, for example. Similarly, payment can be made from a card with a large remaining amount. Further, when the remaining amount is read, information on the additional service can be read at the same time, and payment can be made from a card having a good point return rate, for example.

  As described above, in the embodiment, even when the operation priority of the target system is low, a plurality of cards can be identified, and the payment processing can be performed by identifying the card to be used. For this reason, it is not processed with the card which a user does not intend. Even if the target system is not installed, the operation mode of the card is changed, so that a plurality of cards can be identified. Furthermore, information mounted on a plurality of cards can be processed in conjunction with each other. The communication control according to the embodiment can be performed even for a card on which only one system is mounted.
