In one aspect a fingerprint sensor device includes a touch panel with an integrated touch sensor module. The integrated touch sensor module includes sensing circuitry to generate a sensor signal responsive to detecting a contact input associated with a fingerprint. The sensing circuitry includes a fingerprint sensor to detect the contact input and generate a signal indicative of an image of the fingerprint and a biometric sensor to generate a signal indicative of a biometric marker different form the fingerprint. The generated sensor signal includes the signal indicative of the image of the fingerprint and the signal indicative of the biometric marker different from the fingerprint. The sensing circuitry includes processing circuitry communicatively coupled to the sensing circuitry to process the generated sensor signal to determine whether the contact input associated with the fingerprint belongs to a live finger. In another aspect a device includes a touch screen and an optical sensor module located below the touch screen to provide optical fingerprint sensing.
