Purpose: To provide a laundry system with improved customer services by utilizing portable information terminals having a radiocommunication function such as mobile phones and PHS. Constitution: Upon completion of washing or drying in a laundry machine 102, data for notifying the user of the completion of the treatment are transmitted to the user's mobile phone 100. In addition, when a prescribed time, for example, 10 minutes, elapses after washing or drying finished, a request for permission to unload the laundry is transmitted to the user's mobile phone 100 so as to ask the user whether the clothes can be taken out from the laundry machine 102 or not. The system charges the user when a prohibition response is sent back or there is no response to the request for permission to unload the laundry.
