The objective of the present invention is to enable the equivalent value for products and services to be paid by means of corporate currency in every country in the world. A variable setting unit (201) variably sets the correspondence relationship between a key currency and a corporate currency according to prescribed conditions. On the basis of the correspondence relationship variably set by the variable setting unit (201), and a conversion rate between the key currency and an exchange currency at an activity location identified by an activity location identification unit (212), a corporate currency conversion unit (221) converts an amount in the exchange currency at the activity location, as recognized by an equivalent value recognition unit (213), into an amount in the corporate currency. A corporate currency management unit (222) uses corporate currency associated with a card medium (C) to execute a process for debiting the equivalent value amount after conversion to the corporate currency. A billing processing unit (211) controls the execution of a billing process for the equivalent value amount of the product or service, using the exchange currency at the activity location or the key currency. |
