An electronic settlement system which is similar to cash settlement and which is usable in a gaming parlor is provided. In the electronic settlement system, a mobile phone communicates with a ball lending machine using a contactless IC card to acquire a device ID from the ball lending machine, and transmits a payment request message including the device ID and a user ID to an electronic settlement server. The electronic settlement server notifies an in-store server of a transfer amount from a user account to a settlement provider account, and the in-store server stores the transfer amount as a deposit. In response to a payment request message from the mobile phone, the in-store server instructs the ball lending machine to provide gaming media corresponding to a gaming medium cost, adds an amount corresponding to the gaming medium cost to a consumed amount, and issues a transfer request to a receiving network so as to transfer the consumed amount from the settlement provider account to a gaming parlor operator account. Upon receiving a provision instruction message from the in-store server, the ball lending machine provides gaming media corresponding to the gaming medium cost.
