Electronic Money Transaction System With a Radio Transmitter and Receiver Using a Portable Telephone

The present invention relates to an electronic money transaction system for performing transactions by electrically transmitting and receiving electronic money information stored in an IC card in place of money, and more particularly, to an electronic money transaction system for transmitting and receiving the electronic money information by electromagnetic waves through space.

Hitherto, in a transaction system using electronic money for electrically transmitting and receiving electronic money information, for example, as disclosed in Japanese Patent Application Laid-Open No. 3-92966, an individual as a payer (user) carrying an IC card (electronic wallet) in which electronic money information is stored visits a shop and transmits and receives the electronic money information by using a POS (Point Of Sales) terminal or the like installed at the shop. That is, when an individual wants to receive any service, the individual has to always insert the IC card into the POS terminal or the like to transfer the electronic money information.

As disclosed in the foregoing JP-A-3-92966 for example, the electronic money information is once stored in a terminal installed at a shop, and later, transmitted to an apparatus in a bank center via a communication channel. Consequently, it is necessary to connect communication channels to all of terminals installed at shops.

As mentioned above, in the conventional technique, it is necessary to insert the IC card into an insertion port of the terminal such as a POS terminal in order to transfer the electronic money information. It is, therefore, always necessary for the user to directly touch the terminal. For example, even the user inside a car wants to receive service, the insertion of the IC card into the terminal is still required.

It is, therefore, an object of the invention to enable transactions of the electronic money information to be performed at a place away from the terminal.

In the conventional technique, it is necessary to provide a communication channel to every terminal in order to send the electronic money information once stored in the terminal to be collected later on, at an apparatus in a bank center or the like.

It is, therefore, another object of the invention to collect the electronic money information without providing the communication channel to every terminal.

Means of Solving the Problems

FIG. 4 is a flowchart showing the operation of processes in the electronic money information store 9. Processes after the payer operates the portable telephone terminal 3 and notifies the electronic money information store 9 of payment of the electronic money via the radio telephone equipment 7 are shown. First the electronic money information store 9 outputs the payer discriminating signal 10 (S11) and allows the outputted payer discriminating information to be displayed on the character display 11 (S12). The payer then inputs the information displayed in character form at the input unit 55 of the portable telephone terminal 3 (S13). The information in character form is transmitted to the electronic money information store 9 via the radio telephone equipment 7. The electronic money information store 9 compares the inputted information with the outputted payer discriminating information (S14). When they are coincided, the electronic money transaction with the payer is specified. The result is outputted as the payer discriminated signal 12 (S15) and the signal 12 is displayed on the payer discriminated signal display 13 (S16). The payer of the electronic money recognizes the payer discriminated signal display 13 and sends electronic money information stored in the IC card 1 via the portable telephone terminal 3 by operating the terminal (S17). The electronic money information is sent via the communication channel 8 and stored into the electronic money information store 9. After detecting that the electronic money information was correctly stored (S18), the electronic money information store 9 outputs the electronic money receipt signal 14. After receipt of the electronic money receipt signal 14, the electronic money receipt confirming means 15 instructs an operation to provide service to the payer by the service supply command signal 16. The service supply equipment 17 provides service to the payer according to the service supply command signal 16 (S19).

The operation of the first embodiment will be described in further detail with reference to FIGS. 5 and 6. FIG. 5 shows an example of display of the character display 11, payer discriminated signal display 13, and service supply equipment 17. When the payer operates the portable telephone terminal 3 to notify the electronic money information store 9 of payment of the electronic money via the radio telephone equipment 7, the payer discriminating signal 10 is displayed (D11). At this time, instruction of the operation for the payer is also displayed. Subsequently, the payer discriminated signal 12 is displayed (D12). After completion of transfer of the electronic money information, service supply is displayed according to the electronic money receipt conforming signal (D13).

FIG. 6 is a construction diagram showing a case where the first embodiment is applied to a tollgate system of a parking lot.

In FIG. 6, one display 22 is used and the payer discriminating signal 10, payer discriminated signal 12, and electronic money receipt signal 14 are displayed on the display 22. A passing gate controlling and driving means 23 is provided as service supply equipment. By opening the gate, the supply of the service to the payer is completed. The payer can operate according to the display of, for example, the payer discriminating signal 10 shown in FIG. 5 displayed on the display 22.

The effects of the above-mentioned first embodiment are as follows.

According to the embodiment, the payer who pays the electronic money information to receive the service can perform transactions of the electronic money while being apart from the service supply equipment. By using the payer discriminating information, the transfer of the electronic money can be recorded every service given to the payer. Consequently, the transactions of the electronic money information for a plurality of services can be processed by a single electronic money information store. Further, since the electronic money information is not stored in each service supplying device but is stored in a lump, it is unnecessary to collect money from each of the service supplying devices.

A second embodiment of the invention will be described with reference to FIG. 7.

FIG. 7 is a construction diagram showing the second embodiment of the invention. The construction will be described hereinbelow with reference to FIG. 7. The same components in the second embodiment as those in the first embodiment are designated by the same reference numerals. In the second embodiment, a plurality of service supply equipments 24 are disposed and are controlled by a single electronic money information store 9. In this case, a plurality of the radio telephone equipments 7 are also installed and transmitting and receiving ranges are not overlapped. Each service supply equipment 24 lies within the transmitting and receiving range of each radio telephone equipment 7. Each portable telephone terminal 18 used by the payer receives a signal that specifies one of the plurality of radio telephone equipments 7 and sends the signal specifying the radio telephone equipment 7 together with electronic money information to the electronic money information store 9. The signal is shown in FIG. 8.

FIG. 8 shows the signal sent from the portable telephone terminal 18. In FIG. 8, reference numeral 36 denotes electronic money information and 37 indicates an information signal specifying the radio telephone equipment sent from the radio telephone equipment. By receiving the signal 37 specifying the radio telephone equipment 7 together with the electronic money information, the electronic money information store 9 can recognize that the portable telephone terminal 18 of the payer transmits and receives electromagnetic waves to/from the radio telephone equipment 7.

The operation of the second embodiment with the above construction will be described. In the embodiment, by sending the information by which the radio telephone equipment 7 can be discriminated together with the electronic money information, the electronic money information store 9 can recognize that the information came through which radio telephone equipment 7. Since the service supply equipment 24 is allocated to the radio telephone equipment 7 in a one-to-one manner, the electronic money information store 9 can specify that the electronic money information is sent to which service supply equipment 24. Therefore, the service supply equipment is specified without the operation by the payer of inputting the information specifying the payer as described in the first embodiment.

According to the second embodiment, each payer transfers the electronic money information directly to a single electronic money information store in a manner similar to the first embodiment. However, since it is unnecessary for the payer to input the signal for specifying the payer, the operation is easier than that of the first embodiment.

A third embodiment of the invention will be described with reference to FIG. 9.

FIG. 9 is a construction diagram showing the third embodiment of the invention. The construction will be described hereinbelow with reference to FIG. 9. The third embodiment relates to an example of applying the invention to a parking lot. Reference numeral 60 denotes an antenna provided at the entrance of the parking lot; 61 another antenna; 70 IC cards each storing electronic money information; 62 portable telephone terminals of the embodiment, to which the IC cards 70 are connected, respectively; 63 radio telephone equipment for transmitting and receiving electromagnetic waves to/from the portable telephone terminals 62 via the antenna 60 arranged at the entrance of the parking lot; 64 an electronic money information store for transmitting and receiving electronic information to/from the radio telephone equipment 63; and 65 radio telephone equipment for transmitting and receiving electromagnetic waves to/from the portable telephone terminals 62 via the antenna 61. The electronic money can be stored in the electronic money information store 64. Reference numeral 66 denotes service supply equipment which is a gate of the parking lot in the embodiment; 67 a car to receive the service; 68 cars which are in the parking lot of the embodiment; and 69 a car going out from the parking lot of the embodiment.

The construction of the third embodiment will be described more specifically with reference to FIGS. 10 and 11.

FIG. 10 is a diagram showing the construction of the IC card 70 and the portable telephone terminal 62 shown in FIG. 9. Components similar to those in the first embodiment are designated by the same reference numerals. In addition to the construction of the first embodiment, a memory 73 for storing a number particular to the radio telephone terminal 62 is provided in the third embodiment. A central processing unit 74 has a function of transmitting the information of the particular number memory 73 to the outside according to necessity via the modem 34, radio transmitter and receiver 35, and antenna 4. For example, a telephone number is recorded as a particular number.

FIG. 11 is a diagram showing a construction of the electronic money information store 64 of the third embodiment. Components similar to those in the first embodiment are designated by the same reference numerals. In the third embodiment, a clock 76 for generating time information is provided. A particular number and information memory 77 is also provided.

The operation of the third embodiment with the constructions shown in FIGS. 9 to 11 will be described. In the embodiment, the payer of the car 67 to receive the service has the portable telephone terminal 62 and approaches the service supply equipment 66. The antenna 60 is provided in a range near the service supply equipment 66 and the portable telephone terminal 62 automatically sends a signal indicating that the portable telephone terminal 62 enters the range to the radio telephone equipment 63. The signal includes the particular number stored in the particular number memory 73 in the portable telephone terminal 62. The radio telephone equipment 63 which received the signal recognizes that the portable telephone terminal 62 having the particular number exists at the entrance of the parking lot. After that, the radio telephone equipment 63 notifies the electronic money information store 64 of the particular number. The electronic money information store 64 generates a signal to operate the service supply equipment 66 so that the car 67 can enter the parking lot. After that, in the electronic money information store 64, the time when the car 67 entered the parking lot is read from the clock 76 and is recorded together with the particular number into the particular number and information memory 77.

The operation when the car goes out from the parking lot will be described. A processing flow at this time of the CPU 74 in the portable telephone terminal 62 is shown in FIG. 12. The payer in the car 68 to go out from the parking lot makes a phone call to the electronic money information store 64 by using the portable telephone terminal 62 (S21). The electronic money information store 64 first receives the particular number of the portable telephone terminal 62 which made the phone call. After that, the time when the car entered the parking lot recorded every particular number is read, the present time is detected, and a fee of the parking lot is calculated. The calculated fee is transmitted to the portable telephone terminal 62 which made the phone call, via the radio telephone equipment 65 and the antenna 61. The fee transmitted is displayed on the portable telephone terminal 62 (S26). After receiving confirmation of the payer (S27), the electronic money information is sent from the connected IC card (S28). In the electronic money information store 64, after confirming the transmitted electronic money information, the particular number, information indicative of completion of the payment, and time when the payment is completed are recorded into the internal memory.

The payer in the car 69 who completed the payment moves to the exit of the service supply equipment 66. When the portable telephone terminal 62 of the payer in the car 69 who completed the payment enters the transmission and reception range of the antenna 60, the portable telephone terminal 62 entered the transmission and reception range of the antenna 60 automatically sends the particular number. The radio telephone equipment 63 transmits the sent particular number to the electronic money information store 64. The electronic money information store 64 compares the received particular number with the recorded particular number under which the payment was completed. When it is found from the comparison that the payment has been already made, the present time is acquired. The obtained present time is compared with the recorded time when the payment was completed. When the difference is equal to time required for the movement in the parking lot, a signal to operate the service supply equipment 66 is generated so that the car 69 can go out. As a result of the comparison of the time, when further payment is necessary, it is displayed on a display 71.

According to the third embodiment as mentioned above, the particular number, for example, telephone number of the portable telephone terminal is used and automatically discriminated for discrimination of the service supply. It is, therefore, unnecessary for the payer who is to receive service to operate equipment such as ticket issuing equipment for registering entering time. According to the embodiment, the operation for payment can be also performed at a place away from the service supply equipment, so that there is an effect that it is unnecessary to perform the operation at a place near the service supply equipment. Although the particular number is recorded in the portable telephone terminal in the embodiment, it will be obviously understood that a particular number is recorded in the IC card and the service supply can be discriminated by using the particular number recorded in the IC card without problem.

A fourth embodiment of the invention will be described with reference to FIG. 13.

FIG. 13 is a construction diagram showing the fourth embodiment of the invention. In FIG. 13, reference numeral 25 denotes an IC card in which the electronic money information is stored; 26 a card ID memory storing a card ID particular to the IC card 25; 27 a card ID memory storing IDs of other IC cards; 28 an information processing unit for controlling the information of the card ID memories 26 and 27 and also controlling the transmission and reception of the electronic money information therein; 44 a terminal for controlling electronic information with the IC card 26; 45 an IC card reader/writer connected to the IC card 25, which transmits and receives the electronic information; 46 an IC card non-contact reader/writer that is provided in the terminal 44 and transmits and receives information in a non-contact manner; 47 an IC card as one of the other IC cards; 48 a card ID memory having a particular ID in the IC card 47; 49 another IC card; and 50 a card ID memory having a particular ID in the IC card 49.

FIG. 14 is a diagram showing the constructions of the IC card 25 and the terminal 44 in FIG. 13. As an IC card non-contact reader and writer, a code processing unit 79, a modem 80, a radio transmitter and receiver 81, and an antenna 82 are provided. The code processing unit 79 encodes electronic information from the CPU 51 and decodes the encoded electronic information from the modem 80 to the original electronic information. In the modem, the electronic information is changed to a form of a signal which can be transmitted and received to/from the outside via the radio transmitter and receiver 81. It is obviously understood that the IC card 25 has therein an electronic money information store 78 for storing the electronic money information.

FIG. 15 is a diagram showing the construction of a portable telephone terminal 88 connected to the IC card 49 shown in FIG. 13. Components similar to those in the first embodiment are designated by the same reference numerals. In addition to the construction of the first embodiment, according to the fourth embodiment, a code processing unit 84 has functions of decoding the encoded electronic information, and encoding electronic information and transmitting the encoded information to the modem 34.

The operation of the fourth embodiment with the above construction will be described. In the embodiment, an ordinary payer who is going to receive service makes payment by using the IC card 47. In the IC card 25, the particular ID of the ID memory 48 in the IC card 47 inserted through the terminal 44 is read out and is checked with the ID of a specified IC card stored in the card ID memory 47 in the IC card 25. When it is found that the particular ID of the card ID memory 48 in the IC card 47 is different from the ID stored in the card ID memory 27 in the IC card 25, the IC card 25 functions only to receive the electronic money information. When an encoded particular ID is sent to the IC card 49 via the IC card non-contact reader and writer 46 in the terminal 44, the terminal 44 decodes the code and sends the transmitted ID to the IC card 25. Similarily, the IC card 25 checks the ID stored in the internal ID memory 27 with the ID recorded in the ID memory 50 in the IC card 49. When the two IDs coincide, the information processing unit 28 permits that the electronic money information in the IC card 25 is transferred to the IC card 49. Consequently, the electronic money information stored in the IC card 25 is sent via the modem 80 and radio transmitter and receiver 81. In the portable telephone terminal 88, the transmitted electronic money information is received and is transferred from the IC card reader 32 via the modem 34 to the IC card 49. The IC card 49 stores the transmitted electronic money information into the electronic money information memory 87.

According to the fourth embodiment, the payer of the electronic money who is to receive the service pays the electronic money by inserting the IC card 47 into the terminal 44 provided in the service supply equipment. Further, the electronic money information stored in the IC card 25 in the terminal 44 can be transferred to the IC card 49 in such a manner that the collector operates the electronic money transaction button 56 of the input unit 55 in the portable telephone terminal 88 having the IC card 49 to transmit and receive radio waves via space. An IC card which can receive the electronic money is the IC card 49 only, whose ID coincides with the stored ID. There is an effect that the person who installed the service supply equipment can collect the electronic money stored in the service supply equipment from a remote place by using the IC card 49 without inserting the IC card into the terminal.
