Abstract

A fingerprint sensing module includes a sensor substrate having a sensing side and a circuit side, an image sensor including conductive traces on the circuit side of the sensor substrate, and a sensor circuit including at least one integrated circuit mounted on the circuit side of the sensor substrate and electrically connected to the image sensor. The sensor substrate may be a flexible substrate. The module may include a velocity sensor on the sensor substrate or on a separate substrate. The module may further include a rigid substrate, and the sensor substrate may be affixed to the rigid substrate.
