Abstract: A method of controlling power supply for a fingerprint sensor is provided. The method includes receiving sensor data obtained from the fingerprint sensor; determining whether the received sensor data is a fingerprint form of data; if the received sensor data is the fingerprint form of data, determining an amount of change in sensor data received over a predetermined time is greater than or equal to a predetermined value; and if the received sensor data is not the fingerprint form of data or if the received sensor data is the fingerprint form of data but an amount of change in the received sensor data is less than the predetermined value, allowing the fingerprint sensor to enter a power saving mode.
