作为全球第二大智能手机和半导体厂商,他们没有能力研发和应用跟 Touch ID 相近的技术吗?三星 Galaxy S5 的这种垂直滑动式指纹识别跟 Thinkpad 时代的没有本质区别。同样识别率低,对滑动速度和贴合度以及垂直度有很高要求。
Touch ID 的技术门槛体现在哪?
> The sensor itself works in a swipe manner, which means that you would need to swipe the entire pad of your finger, from base to tip, across the home key to register your fingerprint properly. Also, you would need to keep your finger flat against the home key and swipe at a moderate speed or else it won’t recognise your fingerprint.
