Abstract: An electronic device is provided. The electronic device includes a display and a processor. The processor transmits registration information relating to a user's payment means to an external electronic device, receives state information on the payment means, which is generated by the external electronic device using the registration information, from the external electronic device, and displays an indication corresponding to the state information in relation to an object for representing the payment means, through the display.

Abstract: A method of operating an electronic device capable of operating a plurality of execution environments including a first execution environment and a second execution environment is provided. The method includes generating a first authentication value, using a first application executed in the first execution environment, transmitting the first authentication value from the first application through the second execution environment to a second application executed in the first execution environment, transmitting, based on reception of the first authentication value, a second authentication value and a result of authentication of the user from the second application to the first application through the second execution environment, and performing, when the second authentication value corresponds to the first authentication value, payment based on the result of the authentication, using the first application.

Abstract: An electronic device includes a display, a local wireless communication circuit, a memory, a payment application, and a processor. The memory is configured to store a financial application. The processor is configured to launch the financial application. The processor is also configured to output account information of a user and a graphic user interface (GUI) object associated with the account information on the display. The processor is also configured to launch the payment application in response to selecting the GUI object. The processor is also configured to transmit data of a card linked to the account information to an external device via the local wireless communication circuit.
