Face ID is a new feature in the new gadget from Apple iPhone X, which came to replace the Touch ID. With it, you can unlock your phone only with your own face. Technology works in such a way that it is sharpened on the unique features of a person's face. But the publication Business Insider interested in how the technology manifests itself in the case of twins? Representatives of the company admitted that it could fail.

Nevertheless, Business Insider conducted an independent experiment thanks to the help of two male twins, who are very similar in appearance. The bottom line is simple: they were asked to unlock the iPhone X, which is imprisoned only for one of them and to see if the phone of the two men has a very similar face.

Greg and Bryan Fiber, who agreed to the experiment, recognize that they are not always distinguishable not only by acquaintances, but even by native people, that's why it's doubly more interesting to learn how this technique will deal with it.

As a result of the experiment, it turned out that the iPhone X belonging to Brian did not react to his brother Greg's face, no matter how they tried.

"I was shocked that the iPhone X can catch some difference between me and my brother when most people can not. Yes, and it was a pleasant surprise that my brother will not be able to scour in my phone, "Brian commented.
