Description

  The present invention relates to a train ticket gate system including a mobile phone terminal having an IC card function.

  In recent years, various commercializations are planned in various industries for the purpose of full-scale spread of IC cards. For example, it is an electronic ticket (IC commuter pass) scheduled by JR East. These IC cards are non-contact type IC cards in terms of reliability and application.

  Non-contact type IC cards are classified into “contact type”, “proximity type”, and “neighboring type” according to the communication distance and method (frequency used, etc.), and international standards ISO / IEC10536 and ISO / IEC14443 are respectively used. ISO / IEC15693 is being standardized. For example, the maximum communication distance with the “contact type” reader device is about 2 mm. Similarly, the “proximity type” is about 10 cm and the “neighbor type” is about 70 cm.

  In general, a non-contact type IC card has a business card size and does not have a power source. Therefore, power for operating the IC card is supplied by electromagnetic waves from the reader / writer device.

  Normally, information is input to and output from an IC card through a reader / writer device.

  As described above, normally, an IC card is not provided with a power source, and power for operating the IC is supplied by electromagnetic waves from a reader / writer device, and the power is stipulated by the Radio Law. Then, there is a drawback that the communication distance is shortened.

  Further, since the IC card does not have a display function, when viewing information data recorded on the IC card, there is a disadvantage that the reader / writer device must be separately provided.

  Furthermore, when information on electronic commuter passes is held, it is necessary to perform the information via a reader / writer device each time information data such as deposit is input, which is inconvenient.

  Accordingly, a first object of the present invention is to provide an IC card and a mobile phone terminal equipped with an IC card function that can easily input necessary information and confirm or authenticate the information. A second object is to provide a mobile phone terminal having an IC card function capable of extending the communication distance without changing the shape or the like.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The unit (16) detects an electromagnetic wave transmitted from the reader / writer device (35), and the power supply device (20) receives the detection signal and supplies power to each unit of the IC card function unit (6a). The IC card function unit antenna It operates only when (18) is present in the magnetic field region of the reader / writer device, and supplies power from the power source (9) only for the communication time determined by the CPU (17) to each part of the IC card function unit. And the power supply is stopped based on an instruction from the CPU (17).

  In addition, when the expiration date expires, it is preferable to automatically deposit the money at a predetermined place (electronic periodic issuance station) so that the expiration date of the electronic commuter pass is updated.

  As described above, according to the present invention, the content of information data recorded in the memory of an IC card or a mobile phone terminal having an IC card function can be easily confirmed, and the mobile phone also functions as an electronic commuter pass. It can be a telephone terminal and is convenient. Further, even if recording to the memory of the IC card function unit does not use a reader / writer, the information data can be recorded in the memory of the IC card function unit only by connecting to the mobile company and receiving the information data. Furthermore, the communication distance can be extended by supplying power for operating the IC card as an external power supply from the outside to the power supply circuit of the IC card function unit.

  When making a payment for purchasing a product in the store 4, the communication terminal 2 is held near the reader / writer device 35 (in the magnetic field region 45) provided in the store 4. In the reader / writer device 35, a predetermined electromagnetic wave is transmitted by a transmission circuit 37 serving as a transmission means (step S1). The card function unit 6 receives the electromagnetic wave (step S2). The IC card function unit 6 that has received the electromagnetic wave extracts necessary information data from the memory 15 (step S3), modulates the information data, and transmits it to the reader / writer device 35 (step S4). The reader / writer device 35 receives the information data (step S5) and demodulates it. The demodulated information data is converted into a predetermined format and then displayed on the terminal 36 (step S6). The store clerk of the store 4 confirms the information data displayed on the terminal 36 and is settled (step S7). After the settlement, settlement information data such as a payment method (single payment, installment payment) is transmitted to the communication terminal 2 (step S8). The communication terminal 2 receives the payment information data (step S9) and stores it in the memory 15 of the IC card function unit 6 (step S10). The stored information data can be confirmed by the display unit 12 (step S11).

  FIG. 2 is a system diagram of this embodiment. In FIG. 2, the same reference numerals are given to portions common to FIG. 1, and description thereof is omitted.

  As illustrated, the IC card function unit 6 a includes a power supply device 20. The power supply device 20 is a device for receiving power for operating the IC card function unit 6a from the power source 9 of the mobile phone terminal 5 and supplying the power to each unit of the IC card function unit 6a. The power supply device 20 operates only when the antenna 18 of the IC card function unit 6a exists in the magnetic field region 45 of the reader / writer device, and power is supplied to each unit of the IC card function unit 6a.

Further, in order to avoid wasteful power consumption, power is supplied to each part of the IC card function part 6a only for a minimum necessary time (equivalent to communication time). Therefore, it is possible to increase the communication distance between the IC card function unit 6a and the reader / writer device 35, and useless power is not used. Further, the antenna 18 of the IC card function unit 6a can be made smaller by setting the power supplied to the IC card function unit 6a and the communication distance.

  In the present invention, the reader / writer device 35 is provided at the ticket gate of the train, thereby functioning as an electronic ticket or electronic ticket. Moreover, it functions as an electronic commuter pass by storing information such as the expiry date of the commuter pass in the memory 15 of the IC card function unit 6 of the communication terminal 2 in advance.

  Further, when this communication terminal 2 is used as an electronic wallet, if the balance as the electronic wallet stored in the memory 15 of the IC card function unit 6 is zero or less than a certain amount, it is affiliated. It is advisable to automatically deposit money at a bank or the like through a communication line. In addition, when it is used as an electronic commuter pass, if the expiration date expires, it will automatically be paid into a predetermined place (electronic publishing place) and the processing to update the expiration date of the electronic commuter pass will be performed It is good to.
