<p>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 settlement terminal (7) plays a sound effect indicating settlement completion or settlement failure from a speaker (146), which is detected by a microphone (20) of a portable terminal (5). An e-money application (29) determines whether the detected sound effect is the sound effect for the case of settlement completion or the sound effect for the case of settlement failure. The determination is performed by comparison with audio patterns stored in a storage unit (18). If the sound effect is the sound effect for the case of settlement completion, a charge is performed under fixed conditions. If a determination is made that the sound effect for settlement failure has been detected, value balance is insufficient, and therefore, charge processing is performed immediately.</p> |
