1. An apparatus, comprising:
a fingerprint sensor system;
a touch sensor system;
a user interface system, the user interface system including one or more displays; and
a control system configured for communication with the fingerprint sensor system, the touch sensor system and the user interface system, the control system being further configured to:
receive, from the touch sensor system, an indication of a digit touching a surface of the apparatus in an active fingerprint sensor area of the fingerprint sensor system;
obtain, via the fingerprint sensor system, current fingerprint image data from the digit;
perform a first authentication process based, at least in part, on the current fingerprint image data;
responsive to determining that the first authentication process is an unsuccessful authentication process, obtain, via the fingerprint sensor system, non-digit image data after the digit has been removed from the surface;
perform a second authentication process based, at least in part, on the non-digit image data; and
control the user interface system to provide a notification regarding the outcome of the second authentication process, the notification including at least a visual notification via the one or more displays.
