苹果后悔了：指纹识别重新回归iPhone
iPhone、iPad Pro已经悉数切换到了以Face ID面部识别为主要方式的生物交互形态，不过，安卓那边除了跟进人脸解锁，也同时没有放弃指纹的探索，除了光学屏下指纹，很快，超声波方案也将商用。
数天前(12月13号)，苹果在欧洲提交的一项新专利浮出水面，今年1月份提交刚刚公开。
文件显示，苹果有意愿整合Touch ID和Face ID，其中Face ID作为第一选，Touch ID是备选，甚至Touch ID可以作为Face ID之外的增强加密或者说二重加密。
专利图上引用的手机形态仍旧是宽额头、实体指纹，显然，苹果应该不会在工业设计上走回头路。如果考虑让Touch ID回归，应该也是屏下方案了。
当然，专利尤其是苹果的专利并不一定100%转化产品，也可能仅仅是技术储备或保护原创。毕竟，要想善于做减法的苹果重新拾起指纹，似乎是一件有悖常理的事情。
