Abstract: Disclosed are an electronic device and operating method thereof. The present invention includes recognizing an electrode initially in contact with the user's body part among a plurality of electrodes as a first pair, recognizing the rest of the electrodes contacted with the user's body as a second pair, measuring a current flowing between the recognized first and second pairs, determining a biometric information of the user based on the measured current and load, and outputting the determined biometric information.
