  The method disclosed in Patent Document 1 requires optical means for reading and recognizing a hologram of an ID card at a terminal of the system in order to perform personal authentication, and the input means and display means for personal authentication are cards. It is necessary to provide these functions in the terminal.

  In the technique shown in FIG. 7, personal information such as the cardholder's address and name is stored in the ID card 8, and individual identification information such as the cardholder's fingerprint, voice, and iris is stored in addition to the specific information memory 84. The reference data memory 85 for solid verification / authentication is provided, input from the verification / authentication input detection unit 81 for inputting the fingerprint of the ID card holder, and verified by the verification / authentication function unit 82, Authenticating that According to this configuration, since the individual identification information for verification / authentication is stored in the ID card 8, there is a possibility that the person is authenticated by rewriting the information. In addition, the ID card 8 requires a large current to drive not only the collation / authentication input detection unit 81 but also a mechanism for accessing the outside (access control function unit, external IF, etc.), and battery consumption May be short of current.

  In recent years, when a card with a built-in IC is used for multi-functional authentication such as display and security fingerprints, voiceprints, etc., the current non-contact type IC card has a current and processing time required for communication IC processing. When a large number of functions are processed significantly, there is a problem that the communication IC is not practical due to a shortage of current due to a shortage of current or an increase in processing time.

  The present invention records identification information such as fingerprints and voiceprints on a non-contact type multi-function card having functions such as personal authentication (employee card, pass card, etc.) and authentication of access qualification to a specific facility. It is an object of the present invention to provide a multi-function card system and a multi-function card that can stably supply power for realizing these functions and can improve security.

  FIG. 1 is a diagram showing a principle configuration of the present invention. In the figure, 1 is a multi-function card, 10 is a communication antenna, 11 is an input means for personal physical features such as fingerprints, veins and sweat (for DNA authentication) and a power supply for outputting related information. Power supply antenna to be supplied, 12 is a communication IC with a built-in power supply for wireless communication with a reader / writer, and 13 is a power supply for driving input means such as fingerprints and related information display means. Power supply unit 14, input means including an IC for detecting physical features such as fingerprints (voice prints, finger veins, sweat, etc.), 15 information related to services provided by the multi-function card (for example, available balance) ) Is displayed. 2 is a reader / writer (or RFID or information reader) that reads and writes data of the multi-function card 1 attached to a terminal device (3 to be described later) by contactless (wireless) communication. The terminal device 30 having the above functions (for example, a cash register for store management such as POS) is a display device provided for authentication according to the present invention, and can be added independently of the terminal device 3. . 4 is a line, 5 is connected to each terminal device 3 via a line, manages each terminal device 3 (supply and collection of data), and performs authentication using pre-registered security information, 50 is a host 5 Available for each user (credit card), security information (in the case of a personal authentication card, face, fingerprint, vein, sweat, etc. registered in advance for each user's name) This is a database in which information such as data is stored.

  When the owner of the multi-function card 1 holds the multi-function card 1 near the reader / writer 2 (closes it), the communication antenna 10 and the communication IC 12 communicate with the reader / writer 2, and electromagnetic waves generated from the reader / writer 2 A voltage is generated from the power supply antenna 11, the power supply unit 13 is driven, and the input means 14 and other units are driven. Thereafter, when the user's fingerprint or the like is input from the input means 14, detection information such as the fingerprint is sent to the communication IC, and is output from the communication IC 12 together with the personal information (name and the like) stored in the card. 10 is sent to the reader / writer 2 by radio waves. Information received by the reader / writer 2 is transmitted to the host 5 via the terminal device 3 and the line 4.

  The host 5 searches the database 50 using personal information (name, etc.) sent from the multi-function card 1 and receives the contents of security information (fingerprints, etc.) registered in advance corresponding to the personal information. Authentication is performed by collating information such as fingerprints to determine whether they match, and if they match, the face image (face photo) information registered in the database 50 is extracted and transmitted to the terminal device 3 via the line 4 To do. The terminal device 3 displays the received face image on the display device 30. The operator of the terminal device 3 can determine whether or not the user is the person by comparing the face image displayed on the display device 30 with the face of the owner of the multi-function card 1. When authentication in the host 5 by fingerprint or the like is obtained, data related to the user held in the host 5 (for example, the balance of the user's account) is transmitted to the terminal device 3 together with the face image, The content can be sent from the terminal device 3 to the multi-function card 1 via the reader / writer 2 and displayed on the display means 15.

  The display means 15 of the multi-function card 1 can be realized by using a conventional technique using a liquid crystal having a function of storing and holding with low power consumption, and information such as the balance received from the host is stored by the holder of the multi-function card. It becomes possible to confirm.

  1, the host 5 and the terminal device 3 are connected by a line 4, and the display device 30 displays a face image sent from the host through the same line 4, but the display device 30 and the host are connected. The line can be connected by another line different from the line connecting the terminal device 3 and the host. Thereby, a face image can be transmitted independently of information transmitted and received between the terminal device 3 and the host 5, and confidentiality can be maintained. When the lines are independent, the display device 30 may be provided as a device independent of the terminal device 3 for security check (see FIG. 6 described later).

  According to the present invention, a non-contact type IC card reader / writer and display means are attached to a terminal linked with a host, and means for inputting information on the body characteristics of only the person such as fingerprints, voiceprints, veins, sweat, etc. to the IC card (Biometrics Device) and a power supply antenna are sent from the multi-function card to the reader / writer, and the information from the reader / writer is sent to the host via the terminal for authentication. Authentication is performed on the terminal side by displaying the face image on the display unit on the terminal side, so in a short time triple (personal information in the multi-function card, check by physical features such as user's fingerprint, face held by the host By checking the image and the user's face), unauthorized use of the card by others other than the user can be surely prevented.

  According to the present invention, a power source for detecting body features is generated by a power source antenna separately from the power source of the communication IC, so that a multi-function mechanism is quickly started up.

  In addition, according to the present invention, the user of the multi-function card can authenticate while holding the card, and the processing can be completed in a short time (about 2 to 3 seconds), which is faster, simpler and more secure than before. A system that can use a card can be provided.

It is a display unit that displays the current balance (payable limit) and the like when used as a cash card or a credit card.

  According to the conventional non-contact type IC card, if a multi-function process is performed with a large increase in the amount of current and processing time only by the processing of the communication IC, the current of the communication IC becomes insufficient and the communication is interrupted. In the configuration of FIG. 2, the communication antenna 10 has a single layer as in the conventional case in order to realize multi-functions such as the biometric device 14 ′ including an IC for authentication such as display and fingerprint. Establish communication by connecting to the communication IC 12 in about 3 turns (swirled triple wiring), and turn on the power supply for the multi-function display unit 15 ′ and the biometrics device 14 ′ for authentication such as fingerprints. The number of turns of the power supply antenna 11 to be supplied may be adjusted according to a required voltage (for example, 5.0 V or 3.3 V). The power source / driver unit 13 ′ can be configured by using a known technique for generating a necessary voltage by rectifying the power signal (AC) from the power source antenna 11, and by making it a separate circuit from the communication system. Start-up and current can be secured for a short time.

  When the current capacity of the biometrics device 14 ′ or the display unit 15 ′ is low, the communication antenna 10 can be directly connected to the power source / driver unit 13 ′ from three turns.

  A biometrics device 14 'for inputting a fingerprint (vein, DNA, etc.) for fingerprint authentication, vein authentication, or DNA (sweat component) authentication for authenticating the person is an external view of the multifunction card 1 ( As shown in FIG. 3), it can be provided at the end of the card.

  When the necessary power supply voltage is taken out, as shown in FIG. 4, the voltage may be taken out from any tap that generates the necessary voltage from a plurality of intermediate taps provided for the power supply antenna.

(S2 in FIG. 5), communication is started (S3). On the other hand, when the carrier on the terminal device (reader / writer) side is turned on, in the multi-function card 1, the communication IC 12 and the power supply / driver unit 13 'are turned on (S20 and S30 in FIG. 5). When communication between the multi-function card 1 and the terminal device 3 starts (S3 in FIG. 5), data processing is executed by the communication IC 12, and communication is performed between the terminal device 3 and the multi-function card 1 to perform data processing. Is started (S21). On the power supply / driver unit 13 'side, the circuit operation in the multi-function card 1 is started by power-on (S31 in the figure), the biometrics device operation is executed (S32 in the figure), and the card holder's fingerprint, etc. Information is entered. This information is sent from the communication IC to the terminal device, and in order to execute data verification (S4 in FIG. 5), line connection to the host 5 is performed (S5).

  In the host 5, information (name, fingerprint information, etc.) sent from the multi-function card 1, information such as a fingerprint registered for the name registered in the database (50 in FIG. 1) of the host 5, and Authentication is performed by collating information such as a fingerprint sent from the terminal device 3 (S6 in FIG. 5). When a match is detected by this collation, the face display data (face image data) registered for the user is sent from the host 5 to the terminal device 3 via the line 4, and the terminal device 3 It is received and displayed on the display device (30 in FIG. 1) (S7 in FIG. 5), and the operator compares the face displayed on the display device (30 in FIG. 1) with the face of the cardholder in front of him. Confirm (S8 in FIG. 5). When the operator authenticates (S9 in FIG. 5) and gives an instruction indicating that he / she is a correct user, or an instruction indicating that he / she is an unauthorized user without obtaining approval, Data representing the contents is transmitted from the reader / writer connected to the terminal device 3 to the multi-function card 1. If approval is obtained, the balance (usage limit) of the user sent from the host is also sent to the multi-function card 1.

  When the multi-function card 1 receives this via the communication IC, the balance amount is displayed on the display unit (15 'in FIG. 2). This display can be viewed by the operator of the terminal device 3 and the holder of the multi-function card, and can purchase commodities within the balance. If the authentication is OK (S10 in FIG. 5), the operator of the terminal device 3 passes the product (the product that the holder of the multi-function card wants to purchase) to the holder of the multi-function card 1 (S11). The process is completed (S12). Note that processing such as subtracting the product amount from the balance is omitted.

  In the processing flow of FIG. 5, if the authentication at the host in step S6 is NG, an error display is displayed on the terminal device instead of the terminal face display data in S7 of FIG. The error display displays specific specific pictures and numbers so that they can be clearly identified. As a result, it is possible to check errors only by looking at the display on the display device of the terminal device. This error display can be transmitted from the terminal device to the multi-function card via the reader / writer and displayed on the display unit of the multi-function card (S35 in FIG. 5).
