Classification: CPC G | IPC G

Claim 8:
9. The system of claim 1:
further comprising a touch sensor layer:
interposed between the substrate and the cover layer; and
comprising:
a set of sense electrodes arranged across a top surface of the touch sensor layer; and
a set of drive electrodes arranged across a bottom surface of the touch sensor layer and cooperating with the set of sense electrodes to form an array of drive and sense electrode pairs;

wherein the fingerprint reader is bonded to the bottom surface of the touch sensor layer; and
wherein the controller is configured to, at a second time, preceding the first time:
read a second set of electrical values from the array of drive and sense electrode pairs;
detect presence of the first fingerprint input on the cover layer based on deviations of the second set of electrical values from baseline electrical values; and
in response to detecting presence of the first fingerprint input on the cover layer, read the first set of electrical values from the first multi-layer inductor.
