1. A method of controlling a fingerprint sensor system, the method comprising:
receiving a contact indication corresponding to a contact of an object with a surface of an apparatus;
determining multiple force values corresponding to the contact of the object with the surface during a force monitoring time interval;
determining whether at least a plurality of the multiple force values exceeds a force threshold;
determining whether the plurality of the multiple force values matches a digit touch force pattern;
responsive to determining that the plurality of the multiple force values exceeds the force threshold and matches the digit touch force pattern, controlling the fingerprint sensor system to initiate a fingerprint sensor scan;
estimating, based at least in part on fingerprint image data associated with the fingerprint sensor scan, whether the object is a digit; and
initiating fingerprint image data processing functionality responsive to estimating that the object is a digit.
