指纹识别已成为过去式被代替，这项功能将接替他成为未来的趋势！
首先，要明确的一点是，人脸识别肯定是未来发展的趋势，因为它和指纹识别相比有很大的优点，可以给用户更好的体验，比如只需要看一眼屏幕便可以解锁，不需要动手，冬天在外面带着手套时解锁手机也很方便！
人脸识别应用场景主要不在于身份认证。人脸识别技术由于误识率太高，作为身份认证安全性不够，用于支付更是不行。人脸识别要用在海量人脸中找人，在城市几十万个摄像头中找出所需要的人。
它和屏下指纹相比各有千秋，后置式指纹迟早被前两者淘汰是必然趋势。虽然人脸识别已经越来越成熟，是未来发展的趋势，但我认为人脸识别在未来的一段时间内不会全面取代屏下指纹，未来一段时间很有可能是二者相互共存。
