Why Apple prefers Face ID to the fingerprint sensor under the screen

Last summer, before the official presentation of Apple's iPhone X , all were speculations that varied from one day to the next . That if there would be Face ID, that if not, that there would be a fingerprint sensor on the screen or in the logo of the apple. As you can see, a lot of talk until finally the cake was discovered on September 12 in the keynote .

And it seems that the decision to use the ID system biometric Face ID, was already taken a year before the device came out, and it was so clear because they think it is a much better system than the one that has come using Touch ID so far.

This is how John Gruber, an American blogger who has to invent the Markdown writing system , so used in digital media.

    There were, of course, the first attempts to incorporate a touch ID sensor under the screen as a plan B. However, at Apple they were convinced that Face ID was the way to go more than a year ago. I heard this yesterday from several people at Apple, including engineers who have been working on the iPhone X project for a long time. They stopped developing the Touch ID below the screen, not because they could not do it, but because they decided they did not need it.

That is to say, in Apple they had it crystal clear . Moreover, there are companies that do integrate Touch ID on the screen , personally I think it is a very good identification system and that it could complement the one that is currently being used in the iPhone X. For sample, we share a video in which you can compare between these systems and see a model in action that does, the Vivo X20 Plus UD . This technology, developed by Synaptics, is called Clear ID.

Although everything apparently flows like silk, this system has a couple of disadvantages . The first one is that it can only be mounted on devices that have an OLED screen. Ok, the iPhone X does incorporate it, but as we have been talking about a couple of months here, it is assumed that Apple will launch three different models of iPhone for this year 2018, and the one that is focusing attention It is an economical 6.1 inch device and it does not incorporate this screen technology, it would carry an LCD screen. The OLED panel makes any phone that makes it very expensive .

The other drawback that we find is that the fingerprint sensor integrated into the screen is practically a switch, which can be visible depending on the degree of lighting and the angle at which the screen is viewed, and this seems to be that does not like anything in Cupertino . In addition to this, this sensor emits a pulse of light that must be reflected on the finger of the user, and whose mission is to indicate the owner of the device where he has to place the finger. In short, complications.

In another order of things we talk about security, in 2013 when the Touch ID technology was incorporated into the iPhone 5s it was a kind of revolution. With an error rate of 1 in 50,000, it was assumed that it was materially impossible to unlock a device using any deception technique. It is still more as a very secure system , since in recent models such as the iPhone 8 and iPhone 8 Plus has been incorporated in 2017, and who uses it is usually very satisfied with it.

It also has an advantage that does not have the Face ID, and is able to register different tracks of different people . It is clear, my iPhone is mine and I will not let anyone use it, but there is a range of users who are interested in the possibility of having registered the footprint of any of their children to use the device to convenience.

And referring to security, and despite all the videos we saw from the launch of the iPhone X, Face ID seems to be the cornerstone of Apple for the future , since it has an error rate of 1 in 1,000,000 , and remember that it is a new technology for Californians, who will be polishing and surely improving for the future. So you know, long life to Face ID!
