Abstract

An electronic money system terminates communication to a management center indistinguishably from a case in which the communication to the management center is completed within a predetermined period when it is impossible to complete the communication to the management center within the predetermined period. By switching an operation mode, a predetermined portable terminal is used instead of a communication line to upload and download data. When it is impossible to obtain data required for processing through the communication line, processing is performed based on data possessed up until that time.

9. An electronic money transaction processing method comprising:

a determining step of comparing a payment amount with the amount of credited electronic money and determining whether the amount of the credited electronic money is sufficient to pay the payment amount; and

a menu providing step of providing, when it is determined in said determining step that the payment amount exceeds the credited amount, a menu allowing execution and cancellation of the payment transaction using the electronic money.

10. An electronic money transaction processing method comprising:

a determining step of comparing a payment amount with the amount of credited electronic money and determining whether the amount of the credited electronic money is sufficient to pay the payment amount;

a setting step of setting, when it is determined in said determining step that the payment amount exceeds the credited amount, an amount to be paid using the electronic money in accordance with payment terms; and

an updating step of subtracting the amount to be paid using the electronic money, which has been set in said setting step, from the credited amount.

11. An electronic money transaction processing method according to claim 10, wherein:

the payment terms include terms allowing the giving of change in preset currency units; and

the amount to be paid using the electronic money is obtained by rounding down the amount of the electronic money to a preset currency unit.

12. An electronic money transaction processing method according to claim 10, wherein the payment terms include terms allowing a predetermined input unit to input the amount to be paid using the electronic money.

13. An electronic money transaction processing method comprising:

a first instructing step of instructing a portable electronic device that stores a value of electronic money to update the amount of the electronic money; and

a communicating step of communicating, in response to communication from said portable electronic device that the updating is completed, the updating of the electronic money to a management section for managing the updating of the electronic money.

14. An electronic money transaction processing method according to claim 13, further comprising a second instructing step of again instructing, subsequent to said first instructing step, the updating of the electronic money when the completion of the updating is not communicated from said portable electronic device.

15. An electronic money transaction processing method comprising:

an updating step of updating the amount of electronic money stored in a portable electronic device that stores a value of the electronic money;

a communicating step of communicating the updating of the electronic money to a management section; and

a canceling step of canceling, by a predetermined operation, the updating of the amount of the electronic money and the communication of the updating of the electronic money to said management section.

16. An electronic money transaction processing method according to claim 15, wherein:

the canceling of the processing by the predetermined operation is accepted until said portable electronic device is instructed to update the amount of the electronic money;

the canceling of the processing by the predetermined operation is not accepted within the period from the time at which said portable electronic device is instructed to update the amount of the electronic money to the time at which the completion of the updating is communicated from said portable electronic device; and

when the completion of the updating is communicated, the updating of the electronic money can be communicated to said management section.

17. An electronic money transaction processing method according to claim 15, wherein, subsequent to the cancellation of making a payment using the electronic money, the payment can be made by cash.

18. An electronic money transaction processing method comprising:

an updating step of subtracting part of a payment amount from a portable electronic device that stores a value of electronic money and updating the amount of the electronic money stored in said portable electronic device; and

a communicating step of communicating the partially-paid amount to an external unit or subtracting the amount partially paid using the electronic money from the payment amount and communicating the outstanding amount to the external unit.

19. An electronic money transaction processing method according to claim 18, wherein the payment amount is obtained from the external unit.

20. An electronic money transaction processing method according to claim 18, wherein the external unit includes a cash accounting machine.

21. An electronic money transaction processing method according to claim 18, wherein, in said updating step, the full amount of the electronic money stored in said portable electronic device is used to pay the amount to be paid using the electronic money.

22. An electronic money transaction processing method according to claim 18, wherein, in said updating step, the amount of the electronic money in said portable electronic device is updated, and update information is communicated to a management section.
