An electronic device, comprising: a battery; a display receiving power from the battery; a memory electrically connected to the display; and a processor electrically connected to the memory, a power receiver configured to wirelessly receive power transmitted from a wireless charger connected to an external payment device; a magnetic secure transmission, MST, unit having an antenna for outputting or receiving a payment signal according to an MST payment type; a near field communication, NFC, unit having an antenna for outputting or receiving a payment signal according to an NFC payment type; a movable shield (1130; 1140, 1150); a communication unit configured to communicate with a communication unit of the external payment device wherein the memory is configured to store instructions causing the processor to, when executed, - identify (700, 800) a power state of the battery based on a request for a mobile payment, - when the identified power state is within a first range in which a remaining battery charge is less than a minimum amount of remaining battery charge required for the mobile payment, - receive the power from the wireless charger via the power receiver, - when the identified power state is within a second range greater than or equal to the minimum amount of remaining battery charge required for the mobile payment due to reception of the power, and when a payment type is selected between the MST and NFC payment type in a state where the power is within the second range due to the reception of the power, - stop receiving the power from the wireless charger, - activate the selected payment type, and - complete the mobile payment according to the selected MST or NFC payment type, wherein the movable shield is movable to prevent a signal pertaining to the power reception from the wireless charger from flowing to the antenna radiating a signal according to the selected MST or NFC payment type. a battery;
