1. A method of controlling an active fingerprint sensor area of a fingerprint sensor system, the method comprising:
determining, by a control system of a device that includes the fingerprint sensor system, one or more active fingerprint sensor area criteria, wherein at least one of the one or more active fingerprint sensor area criteria involves a security level; and
controlling, by the control system, the active fingerprint sensor area according to the one or more active fingerprint sensor area criteria, wherein controlling the active fingerprint sensor area involves activating a relatively larger fingerprint sensor area for a single-digit authentication process corresponding to a relatively higher security level and activating a relatively smaller fingerprint sensor area for a single-digit authentication process corresponding to a relatively lower security level.
