Transmitting means. The portable lower-level terminal is provided with sound generation means for generating a sound corresponding to the sound data when sound data is transmitted from at least the higher-level device. As described above, since the sound data is stored in the host device and transmitted to the portable lower terminal when a predetermined sound generation condition is satisfied, it is not necessary to always store the sound data in the portable lower terminal. Thus, the configuration of the lower terminal can be made simpler.

  In the invention of claim 8, the operation program includes a transmission program for transmitting predetermined predetermined common data to the portable lower terminal when the predetermined information is acquired from the portable lower terminal. The processing means transmits the common data to the portable lower terminal in accordance with the execution of the transmission program. In addition, the portable lower-level terminal deletes the common data registered in the common data registration unit when a predetermined communication impossible state is established with the upper level device and the common data registration unit that registers the common data acquired from the higher level device. Common data erasing means. According to this configuration, the operation program of the higher-level device, when the predetermined information is acquired from the portable lower-level terminal (for example, when the portable lower-level terminal is turned on), the predetermined common data (for example, sound Data, image data, video data, etc.) are transmitted to the portable subordinate terminal, so the portable subordinate terminal can receive this common data in advance, and the communication load can be distributed. . Further, in the portable lower-level terminal, the received common data is erased when a predetermined communication impossible state with the higher-level device is established. Therefore, the lower-level terminal always stores the common data. There is no need, and the configuration of the lower terminal can be made simpler.

According to this configuration, when the payment processing is performed on the host device side, the function installed in the host-side non-contact communication means is directly used to perform non-contact communication directly with the non-contact communication medium, and normal payment is performed. Processing can be performed. On the other hand, when the payment processing is performed by the portable lower terminal, the portable lower terminal can function as an interface for non-contact communication, and the function on the upper device side can be used for the payment processing. In particular, when a user wishes to make a payment at a portable lower-level terminal, the portable lower-level terminal can be used for accepting payment, and the functions of the higher-level device can be used for the payment function. Convenient settlement is possible while simplifying the configuration and processing of the lower terminal. Also, with regard to the processing accompanying payment, the processing on the host device side can be easily used in the portable lower terminal, which is very advantageous in terms of design.

The unique information is acquired by the portable terminal 30, and the read unique information (read information) is transmitted to the electronic money settlement machine 10 side.

(Reading process)
Next, reading processing performed in the electronic money transaction system 1 (reading system) configured as described above will be described with reference to FIG. Here, the settlement process performed for the IC card C will be described as an example. In addition, the electronic money transaction system 1 can be used in, for example, an island-shaped tenant such as a side dish shop such as Debert. Although the number of portable terminals 30 used in the electronic money transaction system 1 is not particularly limited, here, a payment process performed in an arbitrary portable terminal 30 will be described.

  First, when the portable terminal 30 is turned on or other instructions are input by operating the key input device 35 or the like, predetermined information of the portable terminal 30 (information that triggers the start, and pressing of the predetermined key is performed). As key press information that can be identified), the information is transmitted to the electronic money settlement machine 10 (FIG. 5 (1)). When the electronic money settlement machine 10 receives this “predetermined information”, the sound data (sound data such as “Thank you”) or sound data of settlement sound such as “Chareen”) or image data (“Thank you very much” Predetermined common data such as “image data” is transmitted to the portable terminal 30 (not shown). When the portable terminal 30 receives this common data, it registers it in the memory 33. When the portable terminal 30 transmits predetermined information (key press information) (corresponding to “when a predetermined sound generation condition is satisfied”), the external interface 21 that transmits sound data stored in the memory 13 is “sound data”. This corresponds to an example of “transmission means”.

  Thus, when predetermined information (key press information) is transmitted from the portable terminal 30, as shown in FIG. 6, in the portable terminal 30, an identifier for identifying the portable terminal 30 (for example, a terminal When there is A and terminal B, an identifier (terminal unique information) that can identify each terminal is transmitted to the electronic money settlement machine 10. The electronic money settlement machine 10 starts up a processing screen (thread) corresponding to each portable terminal 30 and operates a predetermined settlement program (operation program) for performing settlement.

  When information related to payment (information such as the amount of goods) is input by the key input device 35 of the portable terminal 30, this information is transmitted to the electronic money payment machine 10 side. Then, the electronic money settlement machine 10 calculates a total settlement amount based on this information (summing process), generates drawing data corresponding to the settlement amount, and transmits it to the portable terminal 30 ((2 in FIG. 5). )). More specifically, in the electronic money settlement machine 10, on the display device 37 of the portable terminal 30, drawing information including character information specifying characters to be displayed and position information specifying the display position of the character information. Is generated. In this way, instead of transmitting information such as the payment amount to the portable terminal 30 as raw data, it includes character information specifying characters to be displayed and position information specifying the display position of the character information. By transmitting with drawing information, the amount of transmission data can be reduced, and security can be further improved. In addition, the electronic money settlement machine 10 sends drawing information such as “Please despise the card” along with information such as the payment amount (FIG. 5 (3)). Note that the message information such as “Take a card” may be transmitted as prescribed common data when the portable terminal 30 is turned on. In this case, the message information from the electronic money settlement machine 10 may be transmitted. It is read from the memory 33 according to the command information (command information for instructing reading and display of the message). Then, when receiving the drawing data, the portable terminal 30 displays the drawing contents corresponding to the drawing data on the display device 37. The control unit 11 that generates drawing data corresponds to an example of “drawing data generation unit”. The external interface 21 that transmits the drawing data corresponds to an example of a “drawing data transmission unit”.

  Next, the electronic money settlement machine 10 transmits instruction information (RW modulation instruction) that is a condition for starting communication with the IC card C in the modem 43 of the portable terminal 30 and performs polling (FIG. 5 (4)). )). At this time, the electronic money settlement machine 10 transmits a command to be transmitted to the IC card C (such as a command for reading information from the IC chip in the IC card C) to the portable terminal 30 (FIG. 5 (4)). . On the other hand, in the portable terminal 30, when this instruction information (command) is acquired from the electronic money settlement machine 10, the modem 43 is operated, this command is modulated and transmitted to the IC card C, and non-connected to the IC card C. Perform contact communication. The portable terminal 30 acquires information such as unique information (card number, personal information, etc.) and balance (in the case of a prepaid card) uniquely assigned to the IC card C, and modulates the acquired card information. Then, it is transmitted as response information to the electronic money settlement machine 10 (FIG. 5 (5)) (card processing). In the portable terminal 30, when the transmitted card information is stored in the memory 33, it is forcibly deleted after being transmitted to the electronic money settlement machine 10. The control unit 31 corresponds to an example of “non-accumulating means”. Note that the information in the memory 33 may be erased immediately after transmission, or may be volatilized and erased when the power is turned off.

  Then, the electronic money settlement machine 10 performs a known negative determination (determination as to whether or not the IC card is valid) for the IC card C based on the card information received from the portable terminal 30. If it is determined to be valid, a settlement process (for example, a process of calculating a new balance by subtracting the settlement amount from the current balance and registering the billed amount as sales) is performed. It transmits to the terminal 30 (FIG. 5 (6)). When receiving the rewrite instruction information, the portable terminal 30 modulates the instruction information and transmits it to the IC card C, thereby rewriting the information of the IC chip in the IC card C. In the IC card C, when the rewriting is normally performed, the fact is returned as result information. When the portable terminal 30 receives the result information from the IC card C, The result information is transmitted to the electronic money settlement machine 10 side as a card response result (FIG. 5 (7)) (writing process).

  When the electronic money settlement machine 10 receives this card response result, it draws drawing information including character information (message information) such as “Thank you” and position information designating the display position of this character information. It is generated and transmitted to the portable terminal 30 side (FIG. 5 (8)). Further, the electronic money settlement machine 10 transmits ringing information (settlement completion sound such as “Chareen”) to the portable terminal 30 (FIG. 5 (9)) (completion process). Note that the message information such as “Thank you” and the sounding information can be transmitted as prescribed common data when the portable terminal 30 is turned on. In this case, electronic money can be used. It is read from the memory 33 in accordance with the command information from the settlement machine 10. Then, the portable terminal 30 displays the message information “Thank you” and makes a settlement completion sound to end the processing. Note that the portable terminal 30 deletes the common data stored in the memory 33 when communication with the electronic money settlement machine 10 becomes impossible. It corresponds to an example of “erasing means”.

  In this embodiment, the electronic money settlement machine 10 corresponding to the host device is also provided with a wireless reader unit 15 corresponding to the host-side non-contact communication means, and the IC card C (as a recording medium used for settlement) Non-contact communication medium). In this configuration, when the IC card C is deceived with respect to the electronic money payment machine 10 and payment is performed, the electronic money payment machine 10 performs payment processing by a general method. In other words, in this configuration, the control unit 11 (information processing unit) of the electronic money settlement machine 10 (higher level device) is connected between the wireless reader unit 15 (upper side noncontact communication unit) and the IC card C (noncontact communication medium). When non-contact communication is performed, the payment processing is performed based on the read information (identification information, balance, etc.) read from the IC card C by the wireless reader unit 15 and the settlement amount input at the cash register 60 or the like. become. On the other hand, as described above, the control unit 11 (information processing means) of the electronic money settlement machine 10 (higher-order apparatus) is portable when non-contact communication is performed between the portable terminal 30 and the IC card C.
