Abstract:
An electronic device capable of sensing a contact by a peripheral device according to various embodiments may comprise: at least one coil configured to be linked to the peripheral device; and at least one processor configured to sense a contact by the peripheral device. The at least one processor may be configured to: detect a first reception signal from the at least one coil during a first period; apply a first transmission signal to the at least one coil during a second period after the passage of the first period; detect a second reception signal from the at least one coil during a third period after the passage of the second period; and check whether or not the peripheral device has been inserted in the electronic device based on the first reception signal and the second reception signal, wherein the first reception signal is not generated by the peripheral device, and the second reception signal is generated in response to the reception, by the peripheral device, of the first transmission signal.
