摘要:
An improved fingerprint sensing device is provided with multiple sensing apparatus, two or more of which operating on different sensing principles. For example, a capacitive sensor may be integrally formed with an optical sensor on a single substrate. Ideally, the multiple sensing apparatus are disposed such that they may sense nearly identical portions of a fingerprint simultaneously. A primary sensor may be employed to establish the identity of a user based on a fingerprint, while a secondary sensor may be employed to establish that the fingerprint is part of a live human (anti-spoofing). Integrated light sources may be provided to drive an optical sensor. The light sources may also provide visual cues for usage, and enhance the aesthetics of the device.
