Method for providing payment service and electronic device thereof

An electronic device comprising:

• a housing;
• a display exposed on one side of the housing;
• an input device integrally formed with the display, mounted on the housing, or wirelessly connected to the electronic device;
• a user authentication device integrally formed with the display, or mounted on the housing;
• a conductive pattern disposed in the housing, and configured to transmit a signal to an external transaction device;
• a first communication circuit electrically connected to the conductive pattern;
• a second communication circuit configured to provide at least one of cellular or short-range communication;
• a processor electrically connected to the display, the user authentication device, the first communication circuit, and the second communication circuit;
• and
• a memory electrically connected to the processor, and configured to store token information used for payment and information on a plurality of payment cards,
• wherein the memory stores instructions that, when executed, cause the processor to:
• receive a first user input through the input device,
• receive information on at least one of the transaction merchandise or a payment card through the second communication circuit,
• select, after receiving the first user input, one of the plurality of payment cards based at least partly on at least one of the received information or a payment history,
• display the selected card on the display,
• receive user authentication information through the authentication device, and
• after receiving the authentication information, transmit a signal generated based on the token information, to the external transaction device through the first communication circuit and the conductive pattern.
