Extraordinary fingerprint spoofing prevention was found in the Asus Zenfone 4 Pro and Meizu Pro 6 + with the use of Goodix’s live fingerprint sensor (Goodix AC2201), which features a sensor for sensing your finger’s pulse. So, the sensor not only verifies the users' authenticity via an accurate fingerprint match, it also verifies that blood is flowing in the finger. Crooks can no longer cut off limbs to fool biometric verification. Goodix added a separate LED inside its fingerprint sensor package plus included a light sensor integrated onto the fingerprint sensor die. The combination of LED/light sensor is the same components used for the type of heart rate sensors found in most mobile phones.
