Abstract

PROBLEM TO BE SOLVED: To notify a user of the state of communication between a mobile information storage medium stored with a characteristic identifier and a communication terminal and to allow communication between the mobile information storage medium that the user specifies and the communication terminal through the communication system, which provides radio communication between the mobile information storage medium and the communication terminal. SOLUTION: A communication terminal 1 which has radio combination with, for example, an IC card 2 receives the identifier from the IC card 2 via an RWU antenna part 11 by controlling a demodulation part 23 by a communication control part 24 and allows an information part 13 to inform the user that different IC cards 2 are present in, for example, a communicatable area according to the received identifier. Further, an input part 14 accepts the specification input of the IC card 2 from the user, and a CPU 25 or the like confirms that the received identifier matches the specified IC card 2 and allows a radio communication with the IC card 2. Furthermore, processing for the transmission to the IC card 2 is performed by controlling a modulation part 21 by the communication control part 24 and modulating the carrier wave from an oscillation part 22.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system for performing wireless communication between a mobile information storage unit storing a unique identifier and a communication terminal, and more particularly, to a communication system between a mobile information storage unit and a communication terminal. Notifying the user of the communication status, or, for example, even when there are a plurality of different mobile information storage units in the communicable area of the communication terminal, the mobile information storage unit specified by the user and the communication terminal The present invention relates to a communication system that performs communication between

[0002]

2. Description of the Related Art For example, an IC card is constructed by embedding a microcomputer chip or a memory chip on a card substrate of the same size as a credit card or the like, and has been put to practical use in various fields such as finance, distribution, transportation, and medical care. Is planned. Generally, a unique identifier is stored in such an IC card, and the reader / writer uses the identifier to perform an IC card authentication process or the like. The IC card is used as a mobile information storage for storing data such as an identifier.

In a communication system using such an IC card, for example, power is transmitted from a reader / writer to the IC card, and the reader / writer and the IC
Information such as control codes and data is communicated with a card. Such a reader / writer and I
In power transmission and information communication with the C card, a non-contact method using electromagnetic waves is also used in addition to a contact method in which terminals are brought into contact with each other.

FIG. 9 shows an example of the configuration of a communication system that performs gate passage management by using an IC card adopting such a non-contact method. In the system shown in the figure,
A communication terminal 41 having a reader / writer function of performing wireless communication using an antenna and a non-contact type IC card 42 are provided. In this system, when the IC card 42 comes close to the antenna of the communication terminal 41, for example, when the IC card 42 is placed in an area where the communication terminal 41 can perform wireless communication. ,
Wireless communication is possible between the IC card 42 and the communication terminal 41.

[0005] For example, the communication terminal 41 is installed near a gate, and receives an identifier from an IC card 42 possessed by a person trying to pass through the gate and performs authentication processing and the like. In the communication terminal 41, as a result of this authentication processing, a person who is confirmed to have a legally registered IC card 42 is allowed to pass through the gate while opening the gate, while having an unregistered IC card 42. For those who are, close the gate to prevent them from passing. Further, for example, when a fee for passing through the gate is set, the information is stored in the IC card 42 by the communication terminal 41 performing information communication with the IC card 42 of the passer. The amount of the transit fee is reduced from the balance data.

[0006]

However, in the above-described system, communication by a non-contact method, that is, communication using a radio signal or electromagnetic induction is performed between the communication terminal and the IC card. There was a problem that the card holder (user) could not grasp the communication status between the IC card and the communication terminal. In other words, since the situation of such non-contact communication cannot be visually grasped, for example, when the user has a plurality of different IC cards, the communication terminal cannot communicate with any of the IC cards. It is difficult for the user to grasp whether communication is being performed between the users.

On the communication terminal side, for example, if a plurality of different IC cards are present in a communicable area even if the user does not intend, any I
A situation occurs in which it is not possible to determine whether communication with the C card should be performed. That is,
For example, even if each IC card can be identified by the received identifier, it has not been possible to determine which of these IC cards should communicate with. In a communication terminal in a conventional communication system, when such a situation occurs, for example, when communication with a plurality of different IC cards is possible, communication with the IC card which has started communication first is performed. Or a process of simply closing a gate to block a passerby without performing communication with any IC card present in the communicable area.

[0008] However, in the former process, even if the user wishes to withdraw a charge using an IC card of a specific financial institution, for example, a plurality of different financial institutes are placed within the communicable area of the communication terminal. If an IC card is present, there is a problem that communication between the IC card and the communication terminal, which the user does not want the user to withdraw, is performed without permission, and processing such as withdrawal is performed. . Also, in the latter processing, even if, for example, the gate is closed and an alarm is simply issued, it is necessary for the user to grasp the cause of the failure of normal communication between the IC card and the communication terminal. There was a problem that it could not be done. That is, the user specifies the actual cause from various causes, such as whether the IC card owned by the user has a defect or whether the distance between the IC card and the communication terminal is too long. And there was a problem that the original purpose, such as passing through a gate, could not be achieved smoothly.

As described above, in the conventional communication system,
There is a problem that the user cannot grasp the communication status between the mobile information storage device such as an IC card and the communication terminal, and for example, when the user has a plurality of mobile information storage devices, Is that the communication terminal cannot determine which IC card should be used for communication, and the user must specify the mobile information storage unit that the user wants to communicate with the communication terminal. There was a problem that it could not be done.

The present invention has been made to solve such a conventional problem. When wireless communication is performed between a mobile information storage device storing a unique identifier and a communication terminal, the communication terminal and the communication terminal communicate with each other. An object of the present invention is to provide a communication system capable of notifying a user of a communication status with an IC card. Further, the present invention provides a method for performing wireless communication between a mobile information storage unit storing a unique identifier and a communication terminal, for example, when a plurality of different mobile information storage units exist in a communicable area of the communication terminal. Even in this case, it is an object of the present invention to provide a communication system capable of performing communication between a mobile information storage designated by a user and a communication terminal.

[0011]

In order to achieve the above-mentioned object, in a communication system according to the present invention, when a wireless communication is performed between a mobile information storage storing a unique identifier and a communication terminal, such communication is performed. The user is notified of the communication status between them as follows. That is, in the communication terminal, the communication means receives the identifier from the mobile information storage, and the notifying means specifies the mobile information storage to be the communication partner based on the received identifier, and outputs the notification to the user. Therefore, the user can grasp the mobile information storage device that is the communication partner of the communication terminal by the notification by the notification unit, and thereby, the wireless communication is performed between any of the mobile information storage devices and the communication terminal. Can be confirmed.

Further, in the communication system according to the present invention, when wireless communication is performed between the mobile information storage unit storing the unique identifier and the communication terminal, the communication status between them is as follows. Notify the user. That is, in the communication terminal, the communication unit receives the identifier from the mobile information storage unit, and the notification unit detects that a plurality of different mobile information storage units exist in the communicable area based on the received identifier. To the user.

Therefore, the user can recognize from the notification by the notification means that a plurality of different mobile information storage units exist in the communicable area of the communication terminal. When communication between the terminal and the movement information storage unit is not normally performed, the cause can be quickly confirmed by notification. This allows
The user avoids the above-mentioned causes by, for example, moving the mobile information storage unit that does not want to perform communication away from the communication terminal, so that only the mobile information storage unit that wants to perform communication exists in the communication area of the communication terminal. For example, the original purpose of passing through the gate by the above-described IC card authentication processing can be smoothly achieved.

In the communication terminal, for example, since an identifier is received from a plurality of different mobile information storage units and radio signals from a plurality of different mobile information storage units are interfered with each other, the communication terminal has a communication area. The presence of a plurality of different movement information storage bodies can be detected.

Further, in the communication system according to the present invention, when wireless communication is performed between the communication terminal and the mobile information storage unit storing the unique identifier, the mobile information storage for causing communication with the communication terminal is performed. Have the user specify the body as follows: That is, in the communication terminal, the input means receives the designation input of the movement information storage from the user, the communication means receives the identifier from the movement information storage, and the communication control means stores the movement information storage designated as the received identifier. After confirming that the body matches, the wireless communication is performed with the movement information storage unit by the communication unit.

Therefore, even if the user has a plurality of different mobile information storages, the communication terminal communicates with the mobile information storage specified by the user. Communication can be performed between the mobile information storage terminal to be communicated and the communication terminal. Conversely, it is possible to prevent the communication from being performed between the mobile information storage terminal and the communication terminal that are not designated because the user does not want the communication to be performed. As described above, the user can smoothly achieve the original purpose of, for example, passing through the gate by the above-described IC card authentication processing.

Further, in the communication system according to the present invention, when the above-mentioned notifying means notifies that a plurality of different mobile information storage units exist in the communication partner of the communication terminal or in the communicable area of the communication terminal. Then, the user is caused to specify a mobile information storage unit for performing communication with the communication terminal as follows. That is, in the communication terminal, further, the input unit receives a designation input of the movement information storage from the user after the notification output by the notification unit, and the communication control unit matches the received identifier with the designated movement information storage. After confirming that the wireless communication is performed, wireless communication is performed with the mobile information storage unit by the communication unit.

Therefore, for example, after the notification of the mobile information storage device to which the communication terminal is to be transmitted to the user by the notification means, whether or not communication may be performed between the mobile information storage device and the communication terminal. Can be specified by the user, etc.
Further, for example, after the user is notified that a plurality of different mobile information storage units are present in the communicable area of the communication terminal by the notification unit, communication is performed between any of the mobile information storage units and the communication terminal. Can be specified by the user.

As described above, while it is possible to cause the communication between the mobile information storage terminal and the communication terminal designated by the user to perform the communication, the user designates the communication to prevent the user from performing the communication. It is possible to prevent communication between the mobile information storage terminal and the communication terminal that did not exist. This allows the user to use, for example, I as described above.
The original purpose of passing through the gate by the authentication processing of the C card can be smoothly achieved.

Here, the mobile information storage body referred to in the present invention includes not only the above-mentioned IC card, but also a name plate attached to a user, a tag attached to a product or article, and an identification attached to livestock. For example, a plate for delivery, a delivery plate attached to a package or container of a courier service, a plate for number identification attached to an automobile, and the like are also included.

That is, in the same manner as described above, when wireless communication is performed between the mobile information storage unit storing the unique identifier and the communication terminal, any of the mobile information storage units communicates with the mobile information storage unit. It is possible to notify the user of the communication status such as whether communication is being performed with the terminal, and for example, when there are a plurality of different mobile information storage units in the communicable area of the communication terminal. Also, the user can specify a mobile information storage unit for performing communication with the communication terminal. When the movement information storage is attached to an article such as a product, livestock, a car, or the like instead of the user, the designation input of the movement information storage is performed by, for example, a person (user) handling such an article.

Specifically, for example, an identifier or balance data is stored in a number identification plate attached to an automobile, and a communication terminal installed near a gate on a road and a plate communicate by wireless communication. The present invention can be applied to a system for performing authentication processing, deduction of pass-through charges, and the like. In other words, the driver (user) of the vehicle checks whether or not the communication is actually performed between the plate attached to the own vehicle and the communication terminal based on the notified communication status. Can be. Further, even when, for example, another person's car is present in the communicable area of the communication terminal, the driver (user) specifies the plate of the own car and the plate of the own car and the communication terminal. Communication can be performed with the.

The mobile information storage to which the present invention can be applied is not limited to the above-described mobile information storage. The present invention stores a unique identifier, and wirelessly communicates with a communication terminal. The present invention can be widely applied to various mobile information storage units that perform communication.

Note that the unique identifier stored in the IC card 2 may be an arbitrary identifier including numbers, characters, and the like.
In this example, it is assumed that an identifier including a unique identification number is stored in the IC card 2.

The communication terminal 1 has an R for transmitting and receiving a radio signal.
A WU (reader / writer unit) antenna unit 11, an RWU control unit 12 for performing communication processing, authentication processing, and the like, a notification unit 13 for notifying communication status and the like, and an input unit 14 for receiving an instruction from a user and the like are provided. ing. The RWU antenna unit 11 is configured by an antenna and has a function of transmitting and receiving a radio signal.

The RWU controller 12 controls a modulator 21 for modulating data, an oscillator 22 for generating a carrier wave, a demodulator 23 for demodulating data, and communication processing by the modulator 21 and the demodulator 23. A communication control unit 24 and a CPU 25 for controlling the processing units 21 to 24 are provided. The modulation unit 21 includes, for example, a modulator that modulates data into a radio signal, modulates data using the carrier generated by the oscillation unit 22, and transmits the modulated data as a radio signal from the RWU antenna unit 11. Let it. In this example, it is assumed that power transmission from the communication terminal 1 to the IC card 2 is performed, and the modulation unit 21 also uses the RWU antenna unit 11 to supply power to the IC card 2 in a non-contact manner.

The oscillating unit 22 is composed of, for example, an oscillator, and generates a carrier wave used for wirelessly transmitting data and the like. The demodulation unit 23 includes, for example, a demodulator that demodulates a radio signal to data, and demodulates a signal wirelessly received by the RWU antenna unit 11 to reproduce the original data. In this example, the above-described RWU antenna unit 1
1. By performing wireless communication with the modulation unit 21, the oscillation unit 22, and the demodulation unit 23, an identifier is received from the mobile information storage unit (in this example, an IC card), and wireless communication with the mobile information storage unit is performed. Communication means for performing the communication is configured.

The communication control section 24 has a functional circuit controlled by a CPU 25 described later to control communication processing by the modulation section 21 and the demodulation section 23 described above. CPU2
Reference numeral 5 includes, for example, a functional circuit for performing various arithmetic processing, a memory for storing data, and the like, and controls processing in each of the processing units 21 to 24 provided in the RWU control unit 12.
In this example, a table that associates the type of the IC card with the identifier is stored in the memory of the CPU 25, and the CPU 25 specifies the type of the IC card 2 based on the identifier received from the IC card 2. Perform processing.

Specifically, assuming a financial institution as an example, the above-mentioned memory stores, for example, “IC card A of bank A”, “IC card B of bank B”, “IC card C of bank C”,.
・ The type of IC card is stored.
In association with these, identifiers for specifying the type of each IC card are stored. The type of the IC card specified by the identifier is not necessarily the type of the financial institution as described above. For example, the type of the bank account and the user's A configuration in which even the name and the like are specified may be used, and any type of correspondence between the type of the IC card and the identifier may be used.

Further, the CPU 25 determines, for example, that the RWU antenna unit 11 or the like has received identifiers from a plurality of different IC cards 2 or that radio signals from a plurality of different IC cards 2 cause interference. Based on R
It detects that a plurality of different IC cards 2 are present in an area communicable by the WU antenna unit 11 or the like.

The notification unit 13 is composed of, for example, a display for displaying and outputting data. The notification unit 13 displays and outputs the status of communication with the IC card 2 on the screen of the display to notify the user. It should be noted that the notification unit 13 does not necessarily need to use a configuration for notifying the user by display output. In short, any configuration that can notify the user of the communication status or the like may be used, for example, to perform notification by voice. Various notification methods may be used.

In the present embodiment, the notification unit 13 notifies the communication status with the IC card 2 detected by the CPU 25 described above, so that the mobile unit serving as the communication partner can be identified based on the identifier received by the RWU antenna unit 11 or the like. The information storage unit (in this example, an IC card) is specified and notified to the user, and a plurality of different areas are communicable by the antenna unit 11 or the like based on the identifier received by the RWU antenna unit 11 or the like. Notification means is provided for notifying and outputting to the user that the presence of the movement information storage body has been detected.

The input unit 14 is composed of, for example, keys and buttons, and performs a process of receiving an instruction or the like from a user. FIG. 2 shows a configuration example of the input unit 14. That is, in this example, the input unit 14 has a plurality of buttons 31, and the buttons 31 include, for example, “1”, “
A number input button that accepts input of numbers such as 2 ”,...,“ 10 ”, a“ clear ”button that accepts an instruction to clear erroneous input, and a“ confirm selection input ”button that accepts an instruction to confirm input items (Shown as a “select” button in the figure).

The user presses the number input button to input a number, presses a clear button to clear an erroneous input portion, and presses a select button to confirm an input item. Various instructions and the like can be input thereto. In particular,
For example, when inputting the number “1”, the user can input the number “1” by pressing the number input button “1” and pressing the select button. For example, if the user accidentally presses the number input button “2”, the user presses the clear button to delete the number “2” from the screen, and then “1”.
By pressing the number input button and the select button, the number "1" can be input.

The input unit 14 may have any configuration as long as it can receive an instruction or the like from a user. For example, the input unit 14 may be a touch panel on the display screen of the notification unit 13 described above. Buttons as shown in FIG. 2 may be provided. In this example, the input unit 14 constitutes an input unit that receives a designation input of a movement information storage unit (in this example, an IC card) from the user.

When the input of the IC card is accepted by the input unit 14 from the user,
The CPU 25 checks whether or not the identifier received by the RWU antenna unit 11 or the like matches the IC card specified by the user as described above. As a result, if the match is confirmed, the communication control unit 24 to control the IC
Wireless communication is performed with the card by the RWU antenna unit 11 or the like. That is, the CPU 25 confirms whether or not an identifier from the IC card specified by the user has been received, that is, whether or not the IC card exists in an area where communication can be performed by the RWU antenna unit 11 or the like.
When it is confirmed that the IC card exists in the area, the wireless communication is performed with the IC card. Thus, the communication terminal 1 can perform wireless communication with the IC card specified by the user.

In the present embodiment, the CPU 25 and the communication control unit 24 perform the above-described processing, whereby the identifier received by the RWU antenna unit 11 and the mobile information storage unit designated by the user (in this embodiment, the IC card) ) Is confirmed, and communication control means for performing wireless communication with the mobile information storage unit by the communication means (such as the RWU antenna unit 11) is configured.

With the above arrangement, the communication terminal 1
When performing wireless communication with the card 2, the user may be notified of the communication status and the like with the IC card 2 or, for example, when a plurality of different IC cards exist in the communicable area. Even the IC specified by the user
Wireless communication with the card is performed. In addition,
In this example, the communication terminal 1 is configured to further include the notification unit 13 and the input unit 14 in the reader / writer function unit such as the RWU antenna unit 11 and the RWU control unit 12, but for example, the notification unit 13 and the input unit 14 A configuration that is included in the reader / writer function unit may be used.

In this embodiment, the IC card 2 has a ROM or R
A memory such as an AM is provided. For example, a unique identifier is stored in a ROM. Further, it is assumed that the RAM stores, for example, data of the balance of the amount of money deposited by the user at the financial institution. In this example, the IC card 2 itself is not provided with a power supply,
Are configured to operate using power supplied wirelessly from the communication terminal 2. For example, the battery may be provided in the IC card 2 itself, and the IC card 2 may be operated by the battery.

FIG. 3 shows an example of a communication system in the case where a plurality of different IC cards 2 exist in the communicable area of the communication terminal 1. FIG. RWU antenna unit 11 and three IC cards 2
a, 2b, and 2c. As described above, only the RWU antenna unit 11 is shown as a configuration of the communication terminal 1, and other components are not shown. In addition, as the IC card 2, the three IC cards shown in the figure are used.
In order to distinguish the card 2, as described above,
It is shown using symbols such as card 2a, IC card 2b, and IC card 2c.

The communication terminals 1 use the IC cards 2a, 2b,
The area where wireless communication can be performed with the IC card 2c is generally determined depending on the output strength of wireless signals communicated with the IC cards 2a, 2b, 2c and the communication terminal 1, and the like. In FIG. 3, the communicable area R is indicated by a dotted line.
In FIG. 2, two of the three IC cards 2 shown in FIG.
The two IC cards 2 a and 2 b exist in the communicable area R of the communication terminal 1. In this case, the IC card 2a,
2b is in a state where it can communicate with the communication terminal 1, and the IC card 2c is in a state where it cannot communicate with the communication terminal 1. The case where a plurality of different IC cards 2 exist in the communicable region R of the communication terminal 1 includes, for example, a case where one user has a plurality of different IC cards 2 There may be a case where a plurality of users having one or a plurality of IC cards 2 are present near the communication terminal 1 at the same time.

Next, an example of a procedure such as a communication process performed by the communication system including the communication terminal 1 and the IC card 2 described above will be described. First, in the communication terminal 1 installed near the gate, for example, when communication is not performed with an IC card, power is always transmitted to the communicable area R and the IC to which power is supplied is provided. A request signal including a request command for transmitting an identifier from the card 2 is wirelessly transmitted. In this example, the communication terminal 1
To the IC card 2 by polling processing, that is, communication in which an inquiry is periodically made to each communicable IC card 2. In addition, as a method of communication performed between the communication terminal 1 and the IC card 2, any method may be used as long as it is a non-contact communication.

In such a situation, when a person (user) trying to pass through the gate approaches the communication terminal 1, the IC card 2 possessed by the user enters the communicable area R of the communication terminal 1. And the communication terminal 1 in the IC card 2
And the request signal described above. Then, the IC card 2 that has received the request signal transmits a response signal including its own identifier to the communication terminal 1. For example, one IC owned by the user
When only the card 2 exists in the communicable area R,
The communication terminal 1 specifies the IC card 2 based on the identifier received from the one IC card 1.

In this case, on the display screen 32 as shown in FIG. 4, for example, the notification unit 13 informs that communication with the IC card 2 (for example, “card A”) specified by the communication terminal 1 is started. For example, the user is notified using a lighting display. By viewing the display screen 32, the user can grasp and confirm the type and the like of the IC card 2 with which the communication terminal 1 communicates. Note that the timing of such notification is not limited to when communication between the communication terminal 1 and the IC card 2 is started.
For example, while the wireless communication is being performed between them, a notification such as “communication with card A” may be given to the user.

A display screen 3 as shown in FIG.
Before the communication between the communication terminal 1 and the IC card 2 is started, the communication terminal 3 notifies the user of the IC card 2 to be the communication partner of the communication terminal 1 as described above, and communicates with the IC card 2. It is also possible to allow the user to select whether to actually perform the communication between them (for example, the number “1”) or not (for example, the number “2”). That is, in the communication terminal 1, the input unit 14
I according to the designated input received from the user
It controls processing in two cases, such as performing communication with the C card 2 or not performing communication with the IC card 2. Note that the above notification is not limited to the case where only one IC card exists in the communicable area R of the communication terminal 1. For example, when a plurality of IC cards 2 exist in the area R, May also be done if you have.

Also, for example, the communicable area R of the communication terminal 1
When there are a plurality of different IC cards 2 in the
As described above, the communication terminal 1 recognizes that the response signals from the plurality of IC cards 2 are interfering, and that the identifiers from the plurality of different IC cards 2 have been received. In this example, the communication terminal 1 is provided with a function of measuring a predetermined fixed time, and when a plurality of different identifiers (response signals) are received within the predetermined time, the communication possible area is set. It is determined that there are a plurality of different IC cards 2 in R. This determination process is performed by inputting the identifier received by the RWU antenna 11, the demodulation unit 23, the communication control unit 24, and the like to the CPU 25 as described above.

As described above, when the communication terminal 1 recognizes a plurality of different IC cards 2 in the communicable area R, the communication terminal 1 communicates with any of the IC cards 2 existing in the communicable area R, for example. 6, the display screen 34 as shown in FIG. 6 makes it impossible to determine which of the IC cards 2 to communicate with because there are a plurality of different IC cards 2 in the area R. Next, the user is notified that the gate cannot be opened.

With such a message, the user can immediately recognize that there are a plurality of different IC cards 2 in the communicable area R of the communication terminal 1. For example, the IC card 2 to be communicated can be identified. By moving the IC card 2 not to be communicated further away from the communication terminal 1 by bringing the IC card 2 closer to the RWU antenna unit 11 of the communication terminal 1 away from the communication terminal 1, the communication area of the communication terminal 1 is limited. It can be made to exist in R.

That is, when a plurality of different IC cards exist in the communicable area R of the communication terminal 1, the user may not be able to perform normal communication between the communication terminal 1 and the IC card 2. Can be checked quickly,
The time required to avoid the passage restriction state in which the gate is closed due to this cause can be relatively shortened. This allows the user to smoothly achieve the original purpose of passing through the gate.

In addition to notifying the user that a plurality of different IC cards 2 are present in the communicable area R of the communication terminal 1 as described above, a display such as that shown in FIG. The screen 35 can also be used to accept a designation input of the IC card 2 from the user. That is, for example, when a plurality of different identifiers are received by the communication terminal 1, details such as types of a plurality of different IC cards 2 recognized based on these identifiers are displayed on the display screen 35.

In the case of FIG.
To specify and enter the number, and any one of Bank A's card ("Card A"), Bank B's card ("Card B"), and Bank C's card ("Card C") You can select and specify. In the communication terminal 1,
When the specification from the user is received, it is confirmed that the identifier received from the IC card 2 existing in the communicable area R matches the specified IC card 2, and the RWU antenna is communicated with the IC card 2. The wireless communication is performed by the unit 11 or the like.

More specifically, for example, the number “
When "Card A" is designated by inputting "1", the communication terminal 1 confirms that the identifier of Card A has been received, and checks the data of the balance of Card A in the communicable area R from the data. Withdrawing the amount of the passing fee, opening the gate and passing the card to the holder (user) of the card A. In this way, a plurality of different IC cards 2 exist in the communicable area R of the communication terminal 1. Even in the event of a failure, communication can be performed between the IC card 2 specified by the user and the communication terminal 1. That is, communication with the IC card 2 that the user wants to withdraw a fee from is performed. While reliably communicating with the terminal 1, it is possible to prevent communication between the IC card 2 and the communication terminal 1, which the user does not want to withdraw charges or the like.

When it is detected that a plurality of different IC cards 2 exist in the communicable area R of the communication terminal 1, the gate is closed and the user is notified, and necessary for passing through the gate. By preventing the gate from being opened unless the communication process is normally performed between the IC card 2 designated by the user and the communication terminal 1 and the communication terminal 1 is finished, the passage management of the gate can be reliably performed. In the above description, the user specifies one of the IC card 2 recognized based on the identifier received by the communication terminal 1, that is, the IC card 2 recognized as existing in the communicable area R. Although the configuration is used, for example, the user is allowed to specify one of a plurality of different types of IC cards 2 set in advance, and the specified IC card 2 is designated.
When the card 2 exists in the communicable area R, a configuration in which communication is performed between the IC card 2 and the communication terminal 1 may be used.

Further, in the above description, the configuration in which the communication status between the communication terminal 1 and the IC card 2 is notified to the user and then the designation input of the IC card 2 is received from the user is used. It is also possible to adopt a configuration in which a designation input of the IC card 2 is received from the user before or when the IC card 2 existing in the communicable area R is detected. In this case, in the communication terminal 1, for example, when the user approaches the gate, the IC card 2 from the user is displayed on the display screen 36 as shown in FIG.
Accept the specified input. Then, when the designation of the IC card 2 is inputted by the user, the identifier received from the IC card 2 existing in the communicable area R and the designated IC card 2
After confirming that the card 2 matches, the wireless communication with the IC card 2 is performed by the RWU antenna unit 11 or the like.

For example, in the case of FIG.
By operating No. 4, any one of "Card A", "Card B", "Card C", and "Card D" can be designated. For example, when the number “3” is input by the user and “card C” is specified, the communication terminal 1 confirms that the card C exists in the communicable area R based on the received identifier. When it is confirmed that the card C exists in the card C, the amount of the passing fee is deducted from the data of the balance of the card C, and the gate is opened to allow the user to pass.

As described above, by accepting the designation input of the IC card 2 from the user, even when a plurality of different IC cards 2 exist in the communicable area R of the communication terminal 1, the user can communicate. Communication can be performed between the specified IC card 2 and the communication terminal 1 because the user wants to perform the communication, while the IC card 2 and the communication terminal 1 that are not specified because the user does not want to perform the communication. It can be prevented that communication is performed between the two. This allows the user to smoothly achieve the original purpose of passing through the gate.

Here, in the above embodiment, the communication terminal and the IC
Communication with the card using wireless signals,
Although the communication is possible even when the distance between them is relatively large, the form of communication performed between the communication terminal and the IC card is, for example, a non-contact communication. Communication using electromagnetic coupling in a short distance may be performed. That is, for example, when the user holds the IC card over an antenna of a communication terminal or the like, a configuration that enables communication between them can be used. In this case, for example, a plurality of different IC cards are used. The present invention has a particularly effective effect in a situation where the user holds the stored wallet or the like over the antenna of the communication terminal or the like.

In the above embodiment, the case where an IC card is used as the movement information storage is shown. However, the present invention can be applied to various movement information storages such as a name plate and a tag as described above. Things. Further, in the above embodiment, the case where the communication system according to the present invention is applied to a system for performing passage management of a gate has been described.
For example, the present invention can be applied to various systems such as a system for managing entry / exit to a predetermined room and a system for managing transaction processing such as deposits at a financial institution. It is possible to notify the user of the status of the wireless communication described above, and to perform communication between the mobile information storage designated by the user and the communication terminal.
