1. An apparatus, comprising:
a display;
a fingerprint sensor system; and
a control system configured to:
access a data structure that includes historical fingerprint location data, the historical fingerprint location data including information corresponding to prior instances of fingerprint image data obtained from each fingerprint sensor area of a plurality of fingerprint sensor areas of the fingerprint sensor system, wherein the historical fingerprint location data indicates a success ratio S/T for each fingerprint sensor area of the plurality of fingerprint sensor areas, S being a number of successful attempts to obtain prior fingerprint image data from each of the plurality of fingerprint sensor areas and T being a total number of attempts to obtain prior fingerprint image data from each of the plurality of fingerprint sensor areas;
identify, based at least in part on the historical fingerprint location data, a selected fingerprint sensor area of the plurality of fingerprint sensor areas, wherein the control system is configured to identify the selected fingerprint sensor area based, at least in part, on the success ratio;
control the display to prompt, via at least one visual notification on the display, a user to place a digit within or on the selected fingerprint sensor area; and
obtain, via the fingerprint sensor system, current fingerprint image data of the digit from the selected fingerprint sensor area.
