Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable wireless telephone having an electronic money function.

[0002]

[Prior art]

 The use of highly secure IC cards as electronic money has been put to practical use in the UK and elsewhere. The desired amount of money is withdrawn from this IC card at the bank, the amount information is written in advance, and when shopping at a store, the amount of shopping is calculated from the amount of the IC card using the IC card reader / writer at the store. Withdraw. In addition, a desired amount of money is withdrawn again from a terminal of a bank or the like and written in an IC card. For example, as shown in FIG. 4, when depositing 10,000 yen from the terminal 1 such as a bank into the electronic money IC card 2 and buying a 120 yen newspaper at a station stand, if the IC card is put out, The card is inserted into the IC card reader / writer 3 of the stand and the above-mentioned 120 yen is withdrawn, and the balance of the IC card is set to 9880 yen. In some cases, the IC card reader / writer 3 has a key so that it is necessary to input a password.

[0003]

[Problems to be solved by the invention]

 However, the conventional payment method using an electronic money IC card has a major disadvantage in that the balance of the IC card cannot be confirmed. Also, since the method of putting the telephone number information of a mobile telephone such as a portable radio telephone into an IC card has been put to practical use in Europe as the GSM method, it is conceivable to use this IC card as an electronic money IC card. . However, the above-mentioned IC card is miniaturized and fixed in the telephone, so it is difficult to remove the IC card when using it as electronic money. To make it removable, the specifications and structure of existing telephones must be significantly changed.

[0004] An object of the present invention is to add an electronic money function without making a significant change to a mobile phone in order to solve the problems of the related art.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the portable radio telephone according to the present invention comprises: a predetermined amount information area in a predetermined storage means; a writing means for writing the predetermined amount information in the predetermined amount information area; The present invention comprises a reading unit for reading out the amount information, an information transmitting and receiving unit for exchanging the amount information with an external terminal device, and a display unit for displaying the amount information.

In the present invention, an IC card built in a portable radio telephone may be used as the storage means.

In the present invention, the information transmitting / receiving means may include an infrared transmitting / receiving section provided in a portable radio telephone, and an infrared transmitting / receiving section provided in an external terminal device.

Further, in the present invention, the writing means, the reading means, and the display means may use a keypad and a display unit of a portable radio telephone.

Further, in the present invention, the writing means, the reading means, the information transmitting / receiving means, and the display means may use a keypad, a transmission / reception part, and a display part of a portable radio telephone.

[Embodiment of the invention]

 FIG. 1 shows an embodiment of the portable radio telephone of the present invention. In FIG. 1, reference numeral 10 denotes a portable radio telephone, and reference numeral 11 denotes an IC card reader / writer (electronic money terminal) provided in a bank, a store, or the like. In the mobile radio telephone 10, 10a is a control circuit (CPU), 10b is an IC card, 10c is a display, 10d is a keypad, 10e is a modulation circuit, 10f is a demodulation circuit, 10g is a transmission / reception antenna, and 10h is infrared transmission / reception. And 10i are speakers, a hardware part provided to add an electronic money function is an infrared transmitting / receiving part, and a software part is an electronic money memory in an IC card 10b as shown in FIG. An area 10b-1 (amount information area) is provided. In FIG. 2, 10b-2 is a telephone memory area, 10b-3 is a directory file area (telephone and electronic money operation instruction area), and 10b-4 is an OS (basic software) area. The IC card reader / writer 11 includes an infrared transmitting / receiving unit 11a and a control circuit 11b corresponding to the above-mentioned 10h, and an output terminal 11c is connected to a terminal such as a bank.

A telephone number, frequency information, authentication (ID) data, and the like necessary for connection are written in a telephone memory area 10b-2 of the IC card 10b. Is read out to perform the function as a telephone. There is no difference in this point from the conventional portable radio telephone.

Next, the function of electronic money is performed as follows. First, a specific code is input by operating the keypad 10d, the portable radio telephone 10 is set to the electronic money mode, and desired amount information is written in the electronic money area 10b-1 of the IC card 10b from the terminal 11 such as a bank. Leave. At the time of shopping, the sales amount is read from the electronic money area 10b-1 of the IC card 10b and input by the IC card reader / writer 11 which is a terminal of the store. In this case, the balance of the amount written on the IC card 10b is displayed on the display 10c. The exchange of information between the terminal 11 and the portable radio telephone 10 is performed between the respective infrared transceivers 10h and 11a. The infrared transmission format conforms to, for example, IrDA (Infrared Data Association) specifications as shown in FIG.

As described above, the money amount information input / output by infrared rays is input / output to / from the IC card 10b, but this information is used to keep the information secret, such as a secret key method (DES) or a public key method (RSA). It is preferable that the scramble is performed by the following method.

Further, the input and output of the amount information and the ID code by the infrared ray can be performed by using the keypad 10d of the portable radio telephone as described above. However, the present invention is not limited to this. A mode setting switch may be separately provided.

Alternatively, in the electronic money mode, the transfer of money amount information to / from the terminal device may use the function of the portable wireless telephone without using the infrared transmitting / receiving device. However, when the electronic money mode is set, the frequency and signal format are changed or the scramble method is used compared to the telephone mode.

Furthermore, when the electronic money mode and the telephone mode conflict, the electronic money mode may be prioritized or vice versa.

[0017]

[Effect of the invention]

 As described above, according to the present invention, the electronic money function is provided to the portable wireless telephone itself, and therefore, the hardware configuration of the existing portable wireless telephone is not changed at all or minimally. The operation is easy because it is only necessary to add and remove the IC card. In particular, if the input / output of electronic money information is of the infrared ray type, it is less likely to be stolen and is advantageous for confidentiality.
