A method for performing a service related to a credit card with a communication terminal is provided to enable the communication terminal to register/manage a plurality of credit cards, transmit credit data to a payment window of a PC, report the loss of the credit card easily, and search credit card usage information easily. A credit data transfer service is verified and kinds of registered credit cards are displayed when the credit data transfer service is requested(519). The credit data of the selected credit card is displayed when one of the displayed credit cards is selected(523). The displayed credit data is transmitted to a PC by using NFC(Near Field Communication) such as Bluetooth(527), and the PC displays the received credit data in an input column of a payment window. The PC transmits the displayed credit data to a credit card company server when a user requests transmission of the displayed credit data.
