Fingerprint sensor module
First Claim
1. A fingerprint sensor module comprising:
- a substrate;
a fingerprint sensing device mounted on a first side of the substrate;
at least one connection pad arranged on the substrate and configured to electrically connect the fingerprint sensor module to an external component; and
an electrically conductive layer arranged on a second side of the substrate, opposing the first side, forming a back surface of the fingerprint sensing module, wherein the electrically conductive layer controls a potential of a finger in contact with the electrically conductive layer using control circuitry of the fingerprint sensor module.
