A charge settlement system is capable of settling a charge, even during movement, without access to any card-inquiry terminal such as a magnetic credit card. The system is relatively inexpensive to construct and includes a transaction terminal and a portable wireless settlement device. When the transaction terminal requests a payment to the portable wireless settlement device via a communication network, the portable wireless settlement device accesses a server via a wireless communication network for settlement. The portable wireless settlement device includes wireless communication with a transaction terminal; a button section for payment and receipt; a key-entering section; a display device for displaying various kinds of information; and a controller having various types of data stored therein. Payment information is transmitted on a payment mechanism to the transaction terminal, and a payment-confirmation signal is transmitted for payment and receipt, to the transaction terminal via the wireless communication.
