Abstract

There is provided a settlement system comprising a mobile communication terminal, a settlement input device configured to output data of a charge, and a settlement device able to transfer money from a first account to a second account. The settlement input device comprises a first transmission unit configured to transmit the data of the charge to the mobile communication terminal, and a second transmission unit configured to transmit the data of the charge, identification data of the mobile communication terminal, and identification data of the settlement input device to the settlement device. The settlement device comprises a control unit configured to transfer an amount of money determined by the data of the charge from the first account to the second account, and a transmission unit configured to transmit the data of the amount of the transferred money to the mobile communication terminal. The mobile communication terminal comprises a first reception unit configured to receive the data of the charge from the settlement input device, a second reception unit configured to receive the data of the amount of the transferred money from the settlement device, and a display.

Claims

1. A mobile communication terminal which communicates with a first communication device able to transmit data of a list of purchased items or services, and communicates with a second communication device able to generate a settlement report, including data of a list of purchased items or services, based on the data of the list of purchased items or services, the mobile communication terminal comprising:

a local communication unit configured to communicate with the first communication device and receive first data corresponding to data of a list of purchased items or services transmitted by the first communication device;

a radio transmitter/receiver unit configured to communicate with the second communication device and receive second data corresponding to a settlement report, including the first data corresponding to the data of the list of purchased items or services, which settlement report is generated by the second communication device based on the first data transmitted from the first communication device to the second communication device; and

a control unit configured to compare the first data included in the second data received by the radio transmitter/receiver unit with the first data received by the local communication unit, and display a result of the comparison on a display unit,

wherein the result of the comparison displayed by the control unit indicates whether the data of the list of purchased items or services used in a settlement transaction performed by the second communication device is in agreement with the data of the list of purchased items or services received from the first communication device.

2. The mobile communication terminal according to claim 1, wherein the control unit is configured to display, when transmission of a predetermined data is not performed by the radio transmitter/receiver unit even after a predetermined time period elapses from a time the result of the comparison is displayed, a message indicating that the transmission of the predetermined data has not been performed, on the display unit.

3. The mobile communication terminal according to claim 1, wherein the control unit is configured to generate, when the first data is received by the local communication unit, identification data that is varied according to a predetermined rule based on preceding identification data previously generated when previous first data is received, and cause the local communication unit to transmit the currently generated identification data to the first communication device, so that the currently generated identification data is added to the first data which is transmitted from the first communication device to the second communication device.

4. A settlement method for a mobile communication terminal which communicates with a first communication device able to transmit data of a list of purchased items or services, and communicates with a second communication device able to generate a settlement report, including data of a list of purchased items or services, based on the data of the list of purchased items or services, the method comprising:

receiving, by a local communication unit of the mobile communication terminal, first data corresponding to data of a list of purchased items or services transmitted by the first communication device;

receiving, by a radio transmitter/receiver unit of the mobile communication terminal, second data corresponding to a settlement report, including the first data corresponding to the data of the list of purchased items or services, which settlement report is generated by the second communication device based on the first data transmitted from the first communication device to the second communication device; and

comparing, by a control unit of the mobile communication terminal, the first data included in the second data received by the radio transmitter/receiver unit with the first data received by the local communication unit, and displaying a result of the comparison on a display unit,

wherein the displayed result of the comparison indicates whether the data of the list of purchased items or services used in a settlement transaction performed by the second communication device is in agreement with the data of the list of purchased items or services received from the first communication device.

5. The settlement method according to claim 4, further comprising:

displaying, by the control unit, when transmission of a predetermined data is not performed by the radio transmitter/receiver unit even after a predetermined time period elapses from a time the result of the comparison is displayed, a message indicating that the transmission of the predetermined data has not been performed, on the display unit.

6. The settlement method according to claim 4, further comprising:

generating, by the control unit, when the first data is received by the local communication unit, identification data that is varied according to a predetermined rule based on preceding identification data previously generated when previous first data is received; and

transmitting, by the local communication unit, the currently generated identification data to the first communication device, so that the currently generated identification data is added to the first data which is transmitted from the first communication device to the second communication device.
