Abstract
A biometric authentication device uses IR-VCSELs as light sources for performing a better biometric authentication by providing clearer images. A light guide module is introduced to minimize the size of the device. Moreover, the biometric authentication device uses a single image sensing module to gather the vein image and the fingerprint image into the same detection signal which is then analyzed and compared with the pre-stored vein feature data and fingerprint feature data. Therefore, the biometric authentication device can achieve an approach in lowering hardware costs, simplifying circuit designs and providing an outstanding performance.
