A self-service machine using a communications terminal and a service providing method thereof. The self-service machine includes an antenna for receiving a radio signal including identification information of the self-service machine and price information, a radio transceiver for processing the radio signal from the antenna, an information processor for extracting the price information from the signal processed by the radio transceiver if the identification information from the radio transceiver is identical to its actual identification information, a controller for controlling the self-service machine so as to provide a predetermined service according to the price information from the information processor, a service providing unit for providing the predetermined service under the control of the controller, and a memory for storing predetermined information about the service provided by the self-service machine after the provision of service by the service providing unit. Therefore, the self-service machine such as a vending machine or a ticket vending machine, can be used by a cellular phone or a wire/wireless telephone, without the need for cash or a card.
