Description

  The present invention relates to an IC card service information display system used for displaying IC card information in an IC card service used in services such as an area system, a traffic system, a financial system, a public system, and a communication system.

  The IC card uses a built-in non-volatile memory to store information such as storage points, electronic money balance, ticket expiration date, etc., and personal information such as telephone number and date of birth, which can be used for multiple services. Is possible. Such service information is protected by an IC card authentication function and an access management function.

  Specifically, the IC card issuer uses the authentication function and access management function to manage information related to the card usage service enjoyed by the user, and unauthorized access to information in the IC card held by a third party It was not possible to do this, or to prevent “spoofing” of a specific user.

  Service information such as accumulation points, electronic money balances, and expiration dates using these cards can be used as portable display terminals such as POS cash registers, ticket gates, vending machines, ATM service terminals, and portable terminals carried by individuals. I was able to browse.

  However, these portable display terminals are managed by the card issuer in the same manner as the card, and access methods and predetermined authentication processing procedures prescribed in advance by the card issuer are read and service information inside the card is read and displayed. These portable display terminals have some user interface, and the user can select the display contents by the operation specified by the card issuer.

  In recent years, the capacity of nonvolatile memories built in IC cards has increased. In addition, the installed ciphers are diversified, and encryption methods such as a common key / public key are applied according to services, and functions such as authentication and transmission / reception data concealment functions are being strengthened as compared with the prior art.

  Against the background of these technological advances, the number of AP (Application) services mounted on IC cards increases, and multiple and multi-purpose usages such that multiple service providers different from the card issuer share the same card. Began to be considered.

  In this way, in the IC card in which the card issuer is different from the service provider and the services of a plurality of service providers are installed, each service information on the card is managed by each service provider. In order to display, in principle, a mobile display terminal in which the service provider individually defines the processing procedure is necessary.

  Therefore, in order to display multiple service information belonging to each service provider in complex and multipurpose use, even if there is only one card, the number of mobile display terminals corresponding to the service provider is required. For this reason, there is a problem that it is extremely inconvenient for the card user and is wasteful economically.

  In order to solve this, it is assumed that (I) a procedure for reading service information is shared, or (II) a common portable display terminal corresponding to a plurality of service providers is required. However, there is a problem that the display method devised by the service provider and the degree of freedom of content are impaired.

  In addition, for (II), multiple service providers are assumed from the beginning, and the processing of portable display terminals becomes complicated, and in some cases, an unnecessarily troublesome mechanism such as a common terminal guarantee center is required. Thus, there arises a problem that the operation cost of the terminal and the entire service becomes expensive.

  Further, in the multipurpose / multipurpose use, a system constituting a service such as a service terminal prepared by a plurality of service providers and a portable display terminal held by a plurality of users becomes a large-scale in a multi-product terminal configuration.

  It was good if the card issuer was responsible for the entire system and services as before, or it was a single point of contact as before, but it may happen that the share of responsibility and the point of contact are unknown, so the validity of the IC card and various terminals In addition, a mechanism for guaranteeing the trust relationship between the provider and the end user, such as display validity, is required.

  Furthermore, even if each service information from different service providers can be read out in some way, the end user needs to individually specify which information is read out on the portable display terminal, which is convenient for the user. There was a problem of being damaged.

  For example, in a situation where the user has time and reconfirms the information recorded on the IC card, the user is allowed to confirm while selecting service information with a button or the like, but it passes through a traffic ticket gate. Selecting service information while pressing a button in a scene where speed is required significantly reduces convenience.

  In general, non-contact IC cards have begun to be introduced in various fields including telephone cards for public telephones and traffic tickets, and mobile display terminals become complicated operations compared to non-contact simple operability. Will significantly reduce the convenience of the total service.

Thus, the main objects to be solved of the present invention are as follows.
That is, the first object of the present invention is to display a plurality of service information belonging to each service provider in complex / multipurpose use, in order to display the display method devised by the service provider, and the degree of freedom and attractiveness of the contents. Therefore, an IC card service information display system having an operation procedure and mechanism that makes it easy to process the portable display terminal without damaging the display is provided.

  The second object of the present invention is to provide a multi-product terminal configuration such as a service terminal prepared by a plurality of service providers and a portable display terminal held by a plurality of users in combined / multipurpose use. It is intended to provide an IC card service information display system that guarantees the trust relationship between the provider and the end user, such as the validity of IC cards and various terminals and the validity of display.

  A third object of the present invention is to display an IC card service information that does not impair user convenience by a complicated operation in which an end user individually designates which information is read on a portable display terminal depending on usage situations. It is intended to provide a system.

  Other objects of the present invention will become apparent from the specification, drawings, and particularly the description of each claim.

  The IC card service information display system according to the present invention performs authentication processing between the service terminal and the IC card of the service provider that constructs the system, based on the information held in the IC card. Only when the process is normally completed, the service information stored in the non-volatile memory in the IC card is transmitted, the service information transmitted from the IC card is associated with the service terminal, and the portable display held by the service provider In order to reduce the management cost of the terminal that is displayed on the display unit of the terminal and that both terminals themselves will change with the addition or update of the service, the storage location of the service information in the IC card at the terminal Rather than hold, the logical position of service information is associated with the service terminal and passed to the portable display terminal. In addition, the service information and its logical recording position are recorded in order to prevent unauthorized modification of the service terminal or portable display terminal or tampering with communication between the IC card and the terminal. When sending the position to the IC card, a characteristic configuration means for encrypting the data is taken.

  Thus, according to the present invention, service information can be displayed in an IC card safely and inexpensively without troublesome operations.

  More specifically, in order to solve the problem, the present invention achieves the above-mentioned object by adopting each of the novel characteristic constituent means listed below.

That is, the first feature of the display system of the present invention is constructed by a non-contact IC card, a service terminal, and a portable display terminal, which is a multipurpose / multipurpose use, and the non-contact IC card and the portable display terminal are brought close to the service terminal. When used, the service terminal is supplied with operating power using an electromagnetic wave with respect to the contactless IC card, and communicable state between the service terminal and the contactless IC card, further, the service terminal Operating power is supplied to the portable display terminal using electromagnetic waves to enable communication between the service terminal and the portable display terminal, and the non-contact IC card is connected between the service terminal and the contactless IC card. performs verification processing of the key for protecting the display data stored in the contact IC card, when the verification is successful, display data of the non-contact IC card which has been protected in the key And the portable display terminal receives and displays via the service terminal, in the configuration adopting IC card service information display system.

  According to the present invention, if the service terminal prepared by the service provider or the portable display terminal held by the user does not know where the service information exists in the memory in the card, even if the authentication process ends correctly, It is possible to display information.

  In general, when a service terminal or a portable display terminal accesses an IC card, authentication processing is performed, so that user information can be displayed only by adding user information reception and display functions thereto.

  By sharing this procedure in a service system such as a portable display terminal held by a plurality of service providers and users, the specified service information freely created by the service provider can be displayed on any portable display terminal. Is possible. This effect is effective regardless of whether the communication means between the external device and the IC card is in contact or non-contact.

  About the service information communication and display after authentication, since the service terminal prepared by the service provider can specify the information to be displayed, the user can uniquely display it without being aware of the operation. Also, in the portable display terminal held by the user, service information corresponding to each service can be selected with a toggle switch by providing only one input button on the terminal. This effect is also effective regardless of whether the communication means between the external device and the IC card is in contact or non-contact.

  When the IC card transmits the recording position of the service information to an external device such as a portable display terminal associated with the service terminal, and the external device reads the service information from the IC card using the recording position, the external device Is a general sequence in which the IC card sends a command and the IC card returns a response, so that it can be easily implemented in an external device. This effect is particularly effective for a contact IC card based on one-to-one communication, regardless of whether the communication means between the external device and the IC card is contact or non-contact.

  If the recording location or service information is encrypted and transmitted, a third party intercepts or alters the communication contents between the IC card and the mobile display terminal associated with the service terminal, and illegally uses the acquired information. It is possible to prevent tampering with display information. This effect is particularly effective for a non-contact IC card in which communication contents are easily intercepted by eavesdropping or the like, regardless of whether the communication means between the external device and the IC card is contact or non-contact.

  Furthermore, when a non-contact IC card and a user display terminal are stacked on a service terminal or a portable display terminal with a contact IC card electrically contacted is held, there is a difference between direct and indirect, but substantially The service terminal and the IC card communicate with each other, but the service information is greatly different from that displayed on the user's portable display terminal.

  At this time, the operating power of the portable display terminal and the IC card can be supplied from the service terminal, the built-in battery is unnecessary for the portable display terminal, and the display is maintained for a certain period of time. Service content can be confirmed without troublesome operations.

  Hereinafter, in describing embodiments of the present invention with reference to the drawings, as reference information, an IC card example used for implementing the present invention and the IC card and a service provider's service terminal or portable display terminal communicate with each other. An example of a display system for performing the above will be described, and a detailed embodiment of the present invention will be described.

(Reference information 1 IC card example)
First, as reference information 1, an IC card used in the present invention will be described with reference to FIG. FIG. 1A is a functional block configuration example of an IC card according to this IC card example, and FIG. 1B is a file structure diagram of a nonvolatile memory (EEPROM). However, the case where a non-contact IC card is used is illustrated here.

  In the figure, (1) is an IC card (hereinafter referred to as a non-contact IC card), (1-1) is an IC chip mounted on the card (1), and (1-2) is an electromagnetic wave from a terminal such as an external reader / writer. It is an antenna that receives. The IC chip (1-1) includes an RF circuit (1-1a) and a CPU (1-1e) that extract and convert operating power and transmission / reception data between external devices from a signal coming from the antenna (1-2). , And RAM (1-1d), EEPROM (1-1b), ROM (1-1c) and the like.

  The EEPROM (1-1b) is a non-volatile memory and sets information common to composite and multi-purpose use, such as a member ID, a member common key, and a dedicated file 0 (DF0) for storing common points, and each service under that A plurality of dedicated files (DF1, 2, 3 to n) for storing service information provided by the provider are set.

FIG. 2 is a logical configuration in the non-volatile memory (EEPROM) of the contactless IC card according to the present IC card example.
Each logical dedicated file (DF) shown in FIG. 1 is assigned a logical ID.

  In the figure, (1-1-1) stores information common to the first dedicated file (DF0), and (1-1-2) is the second dedicated file (DF1, ID = 01), for example, a ticket. (1-1-3) is a third dedicated file (DF2, ID = 02), for example, a file related to a point service in a distribution mall, and (1-1-4) is a fourth file. A dedicated file (DF3, ID = 03), for example, a file related to an electronic money service.

  Each of these areas is selected by designating the DF ID with a select command from the service provider service terminal (2) or the user portable display terminal (3). Each DF (in this case, DF1, DF2, or DF3) of each individual service has a key information file (IEF) and a service information storage file (WEF). IDs are given to these IEF and WEF files, and the ID of the WEF to be displayed is recorded in the IEF.

  For example, the IEF 11 of DF1 (ID = 01, ticket service) records a key (ABCDEF) related to the ticket service and a logical ID (12) of the WEF in which display data is stored. Furthermore, boarding / exiting history information is recorded in WEF12, and commuter pass information is recorded in WEF13. Similarly, the logical ID (22) of the display content (WEF22) associated with the key is recorded in the IEF 21 under DF2 (ID = 02, point service). Similarly, IEF31 and WEF32 are recorded for DF3 (ID = 03, electronic money service).

  In addition, about the display content of DF1, the boarding / alighting history information of WEF12 has shown that it got on and passed through the ticket gate at 10:02 on February 1, 2001 from Mitaka Station. In addition, the commuter pass information of WEF 13 indicates that the regular valid period is from February 1, 2001 to August 2, 2001: the regular valid section: Shinjuku to Mitaka.

(Reference Information 2 Non-contact IC Card: Service Terminal Display System Example)
Next, as reference information 2, an example of a display system when information in a non-contact IC card is displayed on a service terminal will be described with reference to FIG. In the description of this display system, an example in which service information is displayed at a traffic gate is used.

  In the figure, (1) is a non-contact IC card, (2) is a service terminal, in this example a railway ticket gate, (2-1) an antenna for sending electromagnetic waves to the non-contact IC card (1). , (2-2) is a door for controlling the entrance and exit of people, (2-3) is a control circuit for controlling the door (2-2) and the antenna (2-1), and (2-4) is It is a display part embedded in the antenna part of the service terminal (2).

FIG. 4 shows the basic processing flow with the non-contact IC card and service terminal (ticket gate) used in this display system example.
(I) Card activation: When the non-contact IC card (1) approaches the electromagnetic wave from the service terminal (2) and obtains operable power, it is activated as a result (ST1).

(II) Anti-coregion processing: The service terminal (2) transmits a connection request. The non-contact IC card (1) transmits a response to the terminal. As a result, the service terminal (2) detects the presence of the communicable non-contact IC card (1) (ST2).
(III) Mutual authentication: Authentication communication is performed between the contactless IC card (1) and the service terminal (2), and identification authentication is established (ST3).

  (IV) Selection of IC service area: The service terminal (ticket gate) (2) transmits a select command to the non-contact IC card (1). At this time, DFl ID = 01 (ticket service) is given as an argument. The non-contact IC card (1) sends a normal end response when the designated DF exists (ST4).

  (V) Verification: The service terminal (ticket gate) (2) transmits a verify command to the non-contact IC card (1). At this time, ID = 11 of the IEF 11 and the key “ABCDEF” are given as arguments. When the content of the key held in the IEF 11 matches the content of the key that has been sent, the non-contact IC card (1) returns a normal end response (ST5).

  (VI) Display: The non-contact IC card (1) transmits “010201 1002 Mitaka station boarding” which is the contents of the WEF of the logical address (ID = 12) stored as service information to the service terminal (2). To do. Upon receiving this information, the service terminal (2) displays this information as “ride information” (ST6).

  The above is the basic processing flow by the present display system example between the basic contactless IC card (1) and the service terminal (2). As a result, (I) service key verification between the specific service terminal (2) and the memory file storing the corresponding service information, and (II) the service verification is passed to the service terminal (2) only after successful key verification. Finally, (III) display on the service terminal (2) is performed. As a result, it is possible to display the service information on the service terminal (2) prepared by the service provider without any complicated operation by the user with peace of mind even in complex / multipurpose use.

  If the point service compatible POS (Point of Sales) service terminal (2) tries to display the boarding / alighting history information stored in the WEF 12, the process proceeds to (I) and (II). However, the POS service terminal (2) cannot access DF1 because the ID of DF1 storing the ticket service information is unknown.

  Even if access is possible, since the service-specific key “ABCDEF” recorded in the IEF 11 is unknown, it is difficult to normally complete (IV) service area selection and (V) verification. ) It is impossible to reach the display process.

  In this example, the service terminal (2) confirms that the non-contact IC card (1) is correct by performing verification to transmit the key content as it is in (V), but if higher security is desired, Instead of directly exchanging the contents of the key, it is also possible to authenticate each other by a method such as sending a random number (challenge) called a challenge and response method and data (response) encrypted from the random number.

  In this example, after the verification of (V) is completed, service information is transmitted to the service terminal (2) by (VI), but instead of transmitting the service information, the service information recording position (in this example, ID = 12h) can also be transmitted. In this case, the service terminal (2) continues to transmit a command to read information from the received recording position (ID = 12h) to the non-contact IC card (1), and receives the information “010201 1002 Mitaka Station”. This information can be displayed as boarding information on the display section (2-4).

  Furthermore, the service information (in this case, boarding information) and the service information recording position (in this case, ID = 12h) can be transmitted after being encrypted. The encryption key used at this time can be the key used in the verification of (V) or the authentication described above, and separately, between the service terminal (2) and the contactless IC card (1) in advance. It is also possible to use the defined key itself or the result calculated from this key with a monologous algorithm.

In this example, the non-contact IC card (1) operated by electromagnetic waves from the service terminal (2) has been described. However, although it is inferior in maintainability, a non-contact IC that obtains operating power by incorporating a thin battery such as a paper battery. It can also be a card (1).
In this example, the non-contact IC card (1) that communicates with the service terminal (2) in a non-contact manner has been described. However, although the operability is inferior, the contact IC card having a metal terminal surface is connected to and communicates with it. A service terminal having an interface is also possible.

(Reference information 3 Non-contact IC card: Display system example of portable display terminal)
FIG. 5 shows a portable display terminal of a user according to this display system example.
In the figure, (3) is a portable display terminal, (3-1) is an IC chip, (3-2) is an antenna that receives electromagnetic waves from the outside, (3-1) is an IC chip, and (3-3) is a display. , (3-4) is an input button, and (3-5) is a thin battery.

  The antenna (3-2) and the IC chip (3-1) have basically the same component configuration as the non-contact IC card (1) in FIG. In addition to the non-contact IC card functional block in FIG. 1, a display unit (3-3), an input button (3-4), and a battery (3-5) such as paper lithium are added. The display unit (3-3) is composed of an electrophoretic display element and does not consume power except when the display content is rewritten.

The input button (3-4) is used to toggle the display of service information to be displayed. For example, by continuously pressing the input button (3-4), service information such as WEF12, WEF22, and WEF32 in FIG. 2 can be displayed in order.
In this example, the battery (3-5) is built in, but may be omitted. In this case, service information can be displayed and rewritten only when receiving electromagnetic waves from an external device.

FIG. 6 is a usage example of a scene in which the user confirms the service information of the contactless IC card used in this display system example at an arbitrary location independently of the service terminal.
In the figure, (1) is a non-contact IC card, and (3) is a portable display terminal held by a user. The non-contact IC card (1) and the portable display terminal (3) are used close to each other.

FIG. 7 shows the basic processing flow of the non-contact IC card and the portable display terminal used in this display system example.
Since (I) and (II) are the same as those in FIG. 4, they are simply described. However, in this configuration, the portable display terminal (3) supplies power to the card (1) and is activated. That is, (I) to (III) may be assumed to be processed by replacing the service terminal (2) in FIG. 4 with the portable display terminal (3).

  (I) Card activation (ST1 '), (II) Anti-coregion processing (ST2'), (III) Mutual authentication (ST3 ') (IV) Selection of service area: Mobile display terminal (3) is contactless A select command is transmitted to the IC card (1). At this time, since there is no button input (3-4), it starts from the first service information (ticket service). Specifically, DFl ID = 01h (ticket service) is given as an argument. When the designated DF exists, the non-contact IC card (1) returns a normal end response (ST4 ').

  (V) Verification: The mobile display terminal (3) transmits a verify command to the non-contact IC card (1). At this time, ID = 11h of the IEF 11 and the key “ABCDEF” are given as arguments. The non-contact IC card (1) returns a normal end response when the content of the key held in the IEF 11 matches the content of the transmitted key (ST5 ').

  (VI) Display: The non-contact IC card (1) displays “010201 1002 Mitaka Station Ride” which is the content of the WEF of the logical address (ID = 12) stored as service information for the portable display terminal (3). Send. The portable display terminal (3) that has received this information displays this information as “ride information” on the display element (ST6 ′).

  (VII) Display switching: When the displayed content is different from what is desired, the user presses the input button (3-4) (ST7 '). By this operation, the portable display terminal (3) returns to the process (IV) and selects and collates the ID = 02h (point service) of the argument DF2 for the display of the next “point service”, and displays the service information. indicate. This operation is repeated, and the service information stored in the card (1) is sequentially displayed (ST8 ') by switching to a toggle shape with a button.

  The above is the basic processing flow of the present display system example between the non-contact IC card (1) and the portable display terminal (3) held by the user. As a result, (I) service key verification between the mobile display terminal (3) and the memory file in which the corresponding service information is stored, and (II) the key verification is successful, the service information is transferred to the mobile display terminal (3). Finally, (III) display on the portable display terminal (3) is performed. As a result, the service information can be displayed on the portable display terminal (3) without worrying about the user's troublesome operations even in complex / multipurpose use.

  In this example, the portable display terminal (3) confirms the non-contact IC card (1) by collation in which the contents of the key are transmitted as is in (V). It is also possible to authenticate each other without exchanging the contents, for example, by sending a random number (challenge) called a challenge and response method and data (response) encrypted from the random number.

  In this example, after the verification of (V) is completed, service information is transmitted to the portable display terminal (3) by (VI), but instead of transmitting the service information, the service information recording position (in this example, ID = 12h) can also be transmitted. In this case, the portable display terminal (3) continues to transmit a command to read information from ID = 12h of the non-contact IC card (1), receives the information “010201 1002 Mitaka Station”, and displays the display element (3 -3) display this information as boarding information.

  Further, the service information (in this case, boarding information) and the service information recording position (in this case, ID = 12h) can be transmitted after being encrypted. The encryption key used at this time can be the key used in the verification of (V) or the authentication described above, or separately between the portable display terminal (3) and the non-contact IC card (1). It is also possible to use the key itself defined in, or the result calculated from this key using a unique algorithm.

  In this example, the non-contact IC card (1) that communicates with the mobile display terminal (3) in a non-contact manner has been described. However, although the operability is inferior, the contact IC card having a metal terminal surface is connected to and communicated therewith. It is also possible to provide a portable display terminal having an interface for the above.

(Example embodiment)
FIG. 8 shows a usage example in which service information of a contactless IC card according to the present embodiment is displayed on a portable display terminal in association with a service terminal (ticket gate).
In the figure, (1) is a contactless IC card, (2) is a service terminal (ticket gate) provided by a service provider, and (3) is a portable display terminal held by the user. The non-contact IC card (1) and the portable display terminal (3) are used close to the service terminal (2).

  FIG. 9 shows the basic processing flow of the non-contact IC card (1), portable display terminal (3), and service terminal (2) used in this display system example. Since (I) and (II) are the same as those in FIG. 4 in the reference information, they are simply described. However, in this display system example, the service terminal (2) supplies and activates power to the card (1) and the portable display terminal (3), and the service terminal (2) serves as the core, and the card (1 ) And between portable display terminals (3).

  (I) Card activation (ST1 ″), (II) Anti-coregion processing (ST2 ″), (III) Mutual authentication (ST3 ″) (IV) Service selection: Service terminal (ticket gate) (2) A select command is transmitted to the non-contact IC card (1), and ID == 01h (ticket service) of DF1 is given as an argument.The non-contact IC card (1) is normal when the designated DF exists. An end response is returned (ST4 ″).

  (V) Verification: The service terminal (ticket gate) (2) transmits a verify command to the non-contact IC card (1). At this time, ID = 11h of the IEF 11 and the key “ABCDEF” are given as arguments. The non-contact IC card (1) returns a normal end response when the content of the key held in the IEF 11 matches the content of the transmitted key (ST5 ″).

  (VI) Display: The non-contact IC card (1) displays “010201 1002 Mitaka Station Ride” which is the content of the WEF of the logical address (ID = 12) stored as service information for the portable display terminal (3). Send. Receiving this information, the portable display terminal (3) displays this information as “ride information” without operating the input button (3-4) (ST6 ″).

  The above is the basic processing flow of the present display system example between the non-contact IC card (1), the service terminal (2), and the portable display terminal (3). As a result, (b) service key verification between the service terminal (2) and the memory file storing the corresponding service information and (b) key verification is successful and the service information is serviced by the portable display terminal (3). Display is in progress.

  In particular, when the portable display terminal (3) does not have a built-in battery, it is necessary to receive electromagnetic waves from an external device. As shown in this example, the service information is displayed at the same time when the service is received using the non-contact IC card (1). Therefore, the user is not forced to perform a special operation for displaying service information. As a result, it is possible to display service information on a light and small portable display terminal in a complex and multi-purpose use with peace of mind of the user's complicated operation.

  In this embodiment, the service terminal (2) confirms the non-contact IC card (1) by collation in which the contents of the key are transmitted as they are in (V). It is also possible to authenticate each other without exchanging the contents of, for example, by sending a random number called a challenge and response method and data obtained by encrypting the random number.

  In the present embodiment, the contactless IC card (1) transmits service information to the mobile display terminal (3) after (VI) after completion of the verification of (V). ) Instead of transmitting service information, it is also possible to transmit the service information recording position (ID = 12h in this example) to the service terminal (2).

  In this case, the service terminal (2) sends a command to read information from ID = 12h of the non-contact IC card (1) following (V), receives the information “010201 1002 Mitaka Station”, This information is transmitted to the display terminal (3), and the portable display terminal (3) displays this information as boarding information.

  Furthermore, the service information (in this case, boarding information) and the service information recording position (in this case, ID = 12h) can be transmitted after being encrypted. The encryption key used at this time can be the key used in the verification of (V) or the authentication described above between the service terminal (2) and the card (1). It is also possible to use a key itself defined between 2) or the portable display terminal (3) and the non-contact IC card (1), or a result calculated from this key by a unique algorithm.

On the other hand, between the mobile display terminal (3) and the card (1), the key itself determined in advance between the service terminal (2) or the mobile display terminal (3) and the contactless IC card (1), or from this key. It is also possible to use the result calculated with an original algorithm.
In the present embodiment example, the portable display terminal (3) which operates by obtaining operating power with electromagnetic waves from the service terminal (2) has been described. It is also possible to use the terminal (3).

  In this example, the communication means of the IC card (1) and the portable display terminal (3) has been described as non-contact. However, the IC card is a contact IC card having a metal terminal surface, and the portable display terminal (3) By providing an interface that contacts the metal terminal surface, the communication means can be brought into contact.

  At this time, when the mobile display terminal (3) obtains operating power from electromagnetic waves from the service terminal (2), a part of this power is supplied to the contact IC card (1), and the mobile display terminal (3) is supplied. When a battery is built in, it is possible to supply electric power from the battery to the contact IC card (1).
