The objective is to allow a portable terminal to access a contactless type IC module with a timing that is resistant to receiving effects of other processing and that is unlikely to impart effects to other processing. An asynchronous payment terminal plays a sound effect indicating settlement completion or settlement failure from a speaker, which is detected by a microphone of a mobile terminal. An electronic money application determines whether the sound effect detected by the microphone is a sound effect produced when payment is completed or a sound effect produced when payment is impossible. The electronic money application makes this determination by comparing the sound effect with a sound pattern stored in a storing section of the mobile terminal. If the sound effect is the sound effect for the case of settlement completion, a charge is performed under fixed conditions. If the electronic money application determines that the sound effect indicating that the payment is impossible has been detected, since there is not enough value balance, the electronic money application immediately performs recharging processing. |
