  • [0026]
    Next, the method of use of the electronic money transaction system organized as described above, with the inventive IC card reader/writer being applied thereto, will be explained.
  • [0027]
    The electronic money originator 6 distributes IC cards 10 to banks, retail stores, vending machines and individual users that are members of the system. The bank receives electronic money in exchange for currency, and stores the electronic money in the value box 15 in the external accounting system 52. The value box 15 stores many IC cards, to which electronic money received from the electronic money originator 6 is distributed and stored. Electronic money stored in the IC cards in the value box 15 of the external accounting system 52 is distributed to IC cards in the value box 15 of the bank branch system 1.
  • [0028]
    Each individual member as a user of the electronic money transaction system possesses a distributed IC card 10. The user draws one's deposit of bank account in the form of electronic money and stores it in one's IC card 10 by using the banking teller terminals 12 or auto-teller machine 14 in the bank branch system 1. The user connects one's personal computer 32 equipped with the PC-type IC card reader/writer 33 or one's card telephone 34 to the bank branch system 1 through the public telephone line 7 and can convert the deposit account money into electronic money and store it in one's IC card 10.
  • [0029]
    At the drawing of electronic money, the user's IC card is linked based on its communication function to a specific IC card in the value box 15 of the bank branch system 1 by way of the banking teller terminal 12, auto-teller machine 14, personal computer 32, or card telephone 34. Electronic money stored in the IC card 10 of the value box 15 of the bank branch system 1 is transferred and stored in the user's IC card 10 under control of the transaction management terminal 16. At the same time, the balance of electronic money stored in the IC card 10 in the value box 15 of the bank branch system 1 is subtracted by the amount of electronic money transferred to the user's IC card 10. The drawing of deposits of bank accounts of individuals is the same as the convention.
  • [0030]
    It is also possible for the user to convert currency into electronic money and store it in one's IC card at the bank or IC card originator, instead of drawing the deposit of bank account explained above.
  • [0031]
    Electronic money stored in the user's IC card can be transferred back to the IC card in the value box 15 of the bank branch system 1 by way of the banking teller terminal 12, auto-teller machine 14 or personal computer 32, and deposited in the user's bank account.
  • [0032]
    The user having electronic money stored in one's IC card as explained above can use the IC card to buy goods and services in retail stores that are members of the system.
  • [0033]
    Specifically, for example, the IC card user who intends to buy goods brings the things to the POS terminal counter in the retail store. The clerk operates the POS terminal 21 or 22 to read the barcode label of each thing thereby to enter its price and total the prices of all things, and charges the total price to the customer.
  • [0034]
    The customer who intends to pay for the goods with the IC card puts the card into the card inlet of the electronic money POS terminal 12 or the IC card reader/writer unit 11 attached to the usual POS terminal 22. The user's IC card is linked to the relevant IC card in the value box 15 in the center facility 24 of the retail store by way of the work station 26 over the internal communication line 13. Electronic money in the user's IC card is transferred to the IC card in the value box 15 of the center facility 24, and the POS terminal issues a receipt to complete the transaction process. Electronic money in the user's IC card is subtracted by the amount of payment, and it is added to electronic money in the IC card of the retail store.
  • [0035]
    Different from the foregoing case of a retail store having a number of POS terminals and a value box in the center facility 24 for storing many IC cards, a small retail shop having only a cash register has the installation of an IC card reader/writer and has a shop's IC card for the cash register, thereby allowing customers to pay with their IC cards through the linkage to the shop's IC card by the IC card reader/writer attached to the cash register. Electronic money stored in the shop's IC card can be deposited to the bank account or can also be cashed at the bank.
  • [0036]
    As a manner of organizing a retail store system having POS terminals, these POS terminals are provided with individual IC cards so that transactions with customer's IC cards are carried out temporarily based on the IC cards of POS terminals, and the contents of the IC cards are transferred from the POS terminals to the IC cards in the value box 15 of the center facility 24 afterward when necessary.
  • [0037]
    The vending machine 42 included in the electronic money transaction system is provided with an IC card reader/writer 41 built in the machine and its own IC card so that transaction is carried out with a customer's IC card put in the IC card reader/writer 41 by the customer.
  • [0038]
    Next, an embodiment of the IC card reader/writer with a built-in modem used in the foregoing electronic money transaction system will be explained with reference to Fig. 2, Fig.3 and Figs. 4A, 4B and 4C showing its perspective and cross-sectional structure. Throughout the figures, reference numeral 35 denotes a telephone set, 36 is an IC card reader/writer, 361 is the casing of card reader/writer, 362 and 363 are card slots, 364 is a card holder, 365 is a display window, 366 is an operation board, 367 is a circuit board.
  • [0039]
    The IC card reader/writer 36 of this embodiment is intended to serve as an adapter of the usual telephone set 35, thereby carrying out the electronic money transaction between two IC cards coupled to this card reader/writer, or between one IC card coupled to this card reader/writer and other IC card linked through the telephone line.
  • [0040]
    As shown in Fig. 2 and Fig.3, the IC card reader/writer 36 has a display window 365, e.g., liquid crystal device, and an operation board 366 including a ten-key set, control keys, etc. all arranged on the top of the casing 361, and has a card slot 362 for one IC card 10 provided on the front wall and another card slot 363 for another IC card 10' provided on the side wall of the casing 361.
  • [0041]
    The casing 361 accommodates a circuit board 367, on which circuits for the processing of electronic money transfer, key operation and information display, and of the modem for interfacing with the telephone line are packaged, as shown in Fig. 4A. The IC cards 10 and 10' are in electrical contact with the circuit board 367 by means of a contact device (not shown).
  • [0042]
    The card holder 364 has a cylindrical structure in which the card slot 363 for the IC card 10' is provided, and it can be turned to provide a proper card insertion angle. For example, the cylindrical card holder 364 is slightly turned counterclockwise on the drawing so that the user can easily put in the IC card 10' from the front as compared with the vertical setting of the card slot shown in Fig.4A.
  • [0043]
    In another case of the installation of the IC card reader/writer 36 on the wall as shown in Fig.4B, the card holder 364 is slightly turned clockwise on the drawing so that the user can easily put in the IC card 10' oblique-downwardly for example. Shown in Fig.4C is the case of the slant installation of the IC card reader/writer 36 on the wall, with the card holder 364 being turned properly, so that the user in sitting attitude can easily put in the IC card 10' vertically or at an arbitrary angle.
  • [0044]
    The IC card reader/writer of this embodiment can be used for transferring electronic money between the user's IC card 10 and other IC card 10' possessed by one's child, for example, by putting it in the card reader/writer. It can also be used for the electronic money transaction between the user's IC card 10 and other IC card of other person, bank, etc. (not shown) in a remote place through the telephone line.
  • [0045]
    For the electronic money transaction through the telephone line, only one IC card is needed, which is put in one of the card slots 362 and 363, and electronic money can be transferred between this card and other IC card linked through the telephone line. Accordingly, for the electronic money transaction through the telephone line, the IC card reader/writer suffices to have only one card slot, and even the IC card reader/writer with only one card slot can attain the objectives of this invention.
  • [0046]
    The manner of electronic money transaction proposed by the inventors of the present invention is described in detail in Japanese patent publication JP-A-Hei-7-320646.
  • [0047]
    Next, the internal arrangement of the IC card reader/writer with a built-in modem based on an embodiment of this invention will be explained with reference to the block diagram of Fig.5. In the figure, reference numeral 1104 denotes a loading/unloading circuit, 1105 is a connector, 1106 is an IC card activation control circuit, 1107 is a clock generation circuit,1108 is a reader/writer, 1109 is a read/write control circuit,1110 is a ROM, 1111 is a wavef orm shaping/data extracting circuit, 1112 is an I/O port, 1113 is a main program ROM, 1114 is a RAM, 1115 is a CPU, 1116 is a card check data memory, 1117 is a modem interface circuit, and 1118 is a power supply circuit. The modem interface circuit 1117 is included since the IC card reader/writer of this embodiment is designed to be connected to the telephone line as an adapter of a usual telephone set.
  • [0048]
    Namely, the IC card reader/writer 36 of this embodiment incorporates inside the casing 361 a card slot 362 in which an IC card 10 is put in, a loading/unloading circuit 1104 which manipulates the IC card 10, a connector 1105 which couples with the IC card 10, an IC card activation control circuit 11 which supplies the power voltage and clock signal to the IC card 10, a clock generation circuit 1107, a reader/writer 1108 which writes and reads data to/from the IC card 10, read/write control circuit 1109 which controls the operation of the reader/writer 1108, a ROM 1110 which stores a program run by the CPU 1115 for implementing the ISO-stated basic IC card operations, a wave form shaping/data extracting circuit 1111 which shapes the wavef orm of the signal read out of the IC card 10 and extracts data, an I/O port 1112 which implements data transfer between the reader/writer 1108 and CPU 1115, a ROM 1113 which stores the main program run by the CPU 1115 for the process of electronic money transfer for the IC card 10, a RAM 1114 used for data processing by the CPU 1115, a card check data memory 1116 which stores identification (ID) data used for verifying as to whether the IC card 10 stores electronic money information, a modem interface circuit 1117 which implements the data communication of the card reader/writer with other IC card through the telephone line, and a power supply circuit 1118 which distributes electric power fed in through a connector to the whole circuitry.
  • [0049]
    Although the arrangement of Fig. 5 is shown to treat only one IC card 10, the IC card reader/writer 36 actually has two sets of loading/unloading circuits 1104, connectors 1105, reader/writers 1108 and I/O ports 1112, thereby dealing with two IC cards simultaneously.
  • [0050]
    The IC card reader/writer 36 of this embodiment operates as follows. The user puts the IC card 10 into the card slot 362, and the card is loaded automatically by the operation of the loading/unloading circuit 1104.
  • [0051]
    The CPU 1115 detects the IC card 10 in a state of contact with the connector 1105, and operates on the control circuit 1106 to supply the power voltage and clock signal to the IC card 10. Subsequently, the CPU 1115 reads out the ID data from the IC card 10 through the connector 1105 and reader/writer 1108.
  • [0052]
    These operations are carried out in compliance with the ISO standard by the program stored in the ROM 1110. The program includes a format converting routine which makes the data format match with the IC card protocol, an IC card activating routine, and a card reading/writing routine.
  • [0053]
    The CPU 1115 compares the ID data read out of the IC card 10 with the record in the card check data memory 1116 thereby to verify the electronic money information in the IC card 10. Upon certifying the information stored in the IC card 10, the IC card reader/writer 36 is ready to run the main program of electronic money processing stored in the ROM 1113. The foregoing operations take place automatically regardless of the operational state of other IC card handling apparatus which is linked to the IC card reader/writer 36 through the telephone line.
  • [0054]
    Fig. 6 shows the internal arrangement of the IC card 10 of electronic money. In the figure, reference numeral 103 denotes a contact device, 104 is a CPU, 105 is an EEPROM, and 106 is a ROM.
  • [0055]
    Namely, the IC card 10 has a contact device 103 for the communication of the power voltage and the clock, reset, data and other signals with the circuitry of card reader/writer, and incorporates a CPU 104 which controls the operation of the card, a re-writable EEPROM 105 which memorizes data of electronic money, etc., and a ROM 106 which stores a program of the card.
  • [0056]
    The CPU 104 implements the data input/output protocol in compliance with the ISO standard and the encryption process based on the program in the ROM 106. Electronic money information and transaction history information are memorized in the EEPROM 105.
  • [0057]
    The IC card reader/writer 36 of this embodiment has its basic operation carried out by the main program stored in the ROM 1113 which is accommodated in the casing 361 of card reader/writer 36. Based on the confinement within the IC card reader/writer of the function of access to electronic money in the IC card 10, the security against incorrect operations on the IC card and illegal access to electronic money in it can be enhanced.
  • [0058]
    Fig. 7 shows a different external structure of the inventive IC card reader/writer. This IC card reader/writer has a liquid crystal display window 368 which takes up the entire top surface of the casing 361. The display window 368 displays information, and also displays the keytops of a ten-key set and function keys, thereby functioning as a touch-panel operation board. This structure provides the enhanced visibility of display and operability of the IC card reader/writer.
  • [0059]

In this example, ¥3000 of electronic money has been transferred from IC card a to IC card b. According to the operational manner shown in Figs.12A and 12B, the user of the receiving device B is simply required to put in the IC card (step 1201'), and can receive electronic money by the automatic operation on the side of the sending device A.
  • [0084]
    Next, another operational procedure of receiving electronic money into IC card a on the device A from IC card b on the device B which is linked through the telephone line, as in the case of the preceding example of Figs.11A and 11B, will be explained on the flowchart of Figs.13A and 13B. This is the same case where the amount of money transfer is determined mainly by the receiving party, e.g., money reception by a mail-order retailer from a customer who has bought commodities.
  • [0085]
    In the figures, operations and displays 1301-1314 on the part of the device A and operations and displays 1301'-1314' on the part of the device B are identical to those 1201-1214 and 1201'-1014', respectively, shown in Figs.12A and 12B. The procedure of Figs.13A and 13B is different from Figs.12A and 12B in that the user of the sending device B has operations (1315'-1317') of confirming the amount of money to be sent which has been determined and entered by the user of the receiving device A.
  • [0086]
    Following the entry of money amount to be received, the device A remote-controls the device B over the telephone line to display a sign of prompting the confirmation of the amount on the display window of the device B as shown by 1316'. In response to the pushing of Enter key 1413 (step 1317') by the user of device B upon confirming the money amount (step 1315'), the outgoing and incoming of electronic money take place:(steps 1311 and 1311').
