Abstract

A biometric identification apparatus includes a control module, a fingerprint identification module including a fingerprint scan controller and a fingerprint receiver, a pulsatile blood flow detection module including one or multiple light sources and a photo detector, and a holder body defining a fingerprint identification zone and a pulsatile blood flow identification zone. In application, the user simply needs to press the fingertip of one single finger on the fingerprint identification zone and pulsatile blood flow identification zone of the holder body so that the biometric identification apparatus can detect user's fingerprint and pulsatile blood flow signals, fetch and convert characteristic data of detected signals, and then match fetched fingerprint and pulsatile blood flow characteristic data with respective reference data for security access control. The application of this dual-biometric identification technology greatly increases the cracking difficulty, achieving better anti-theft function.
