Five years ago, Apple made fingerprint scanners on smartphones popular. Now the company may have found a better technology to replace it. According to Mark Gurman of Bloomberg, the Cupertino-based company is exploring 3D facial detection as a replacement for Touch ID fingerprint authentication. From the article: This is powered by a new 3-D sensor, added the people, who asked not to be identified discussing technology that's still in development. The company is also testing eye scanning to augment the system, one of the people said. The sensor's speed and accuracy are focal points of the feature. It can scan a user's face and unlock the iPhone within a few hundred milliseconds, the person said. It is designed to work even if the device is laying flat on a table, rather than just close up to the face. The feature is still being tested and may not appear with the new device. However, the intent is for it to replace the Touch ID fingerprint scanner, according to the person.
