Differences between Touch ID and Face ID

For us who use cell phones on a daily basis, whether for work, studies or simply as a hobby, it is important to keep all our information protected in a secure manner.

As we know Apple devices have years using the method unlock Touch ID on their devices using the Home button, but since the launch of the iPhone X Apple decided to remove the Home button and add a release system using facial recognition Face ID. 

While the vast majority of Apple consumers didn’t think it was the best idea in the world to have removed the Home button and added Face ID, others did find it cool and innovative. Even because they can add and configure Face ID for two different people.

When it comes to unlocking your cell phone with Touch ID, it doesn’t matter if you are wearing gloves or have wet fingers, it will still unlock. Likewise, Face ID will recognize your face whether you wear glasses (either sun or reading) or are wearing a mask, it will still recognize your face.

Differences between Touch ID and Face ID

So is Touch ID or Face ID better? Next we will see what are the differences of these two unlocking methods and which is faster.

Touch ID

Apple introduced Touch ID in 2013 at the launch of the iPhone 5s, from there the other mobile devices that Apple has been announcing over the years have this unlocking method integrated.

The Home button is lined with sapphire crystal, which allows the fingerprint to be detected. This sensor uses advanced capacitive touch technology in order to obtain a high resolution image of the fingerprint from small sections of subepidermal layers. Touch ID classifies the fingerprint into one of three basic types: arc, loop, or spiral.

Touch ID can read multiple fingerprints , and it is capable of doing so at a 360 degree angle and thus creates a mathematical presentation of the fingerprint and compares it with the data already recorded to identify the match and thus be able to unlock the device.

All fingerprints are unique so it is impossible for two different fingerprints to be close enough for Touch ID to register as a match. You can use Touch ID to buy apps and songs instead of entering your Apple ID account key. The best thing about this unlocking system is that it is super easy to configure.

This locking system does not store photos of your fingerprint, it only uses a mathematical representation, which makes it impossible for someone to redesign the image of your fingerprint from this stored data.

Face ID

Face ID technology was launched by Apple in 2017 at the launch of the iPhone X, where Apple announced that it would no longer have a Home button with a Touch ID unlocking system but would have facial recognition, so it is only available in iPhone X or later.

The TrueDepth camera accurately captures facial data by projecting and analyzing more than 30,000 invisible points that create a depth map of the face from which an infrared image is obtained.

Face ID automatically adapts to changes in appearance, such as makeup or facial hair growth. If there is a very noticeable change in the face, Face ID confirms the identity through the user’s code before updating the face data and it is quite easy to configure .

It is designed to identify your face regardless of whether you wear many accessories on your face. It works indoors and outdoors, even in total darkness, so under any circumstance you will be able to unlock your cell phone.

Touch ID or Face ID?

After many tests they have come to the conclusion that Touch ID is a little faster than Face ID facial recognition. The difference is minimal. It all depends on the comfort and preference of the consumer, since for some it is faster and more comfortable to lift the phone and for others it is better to simply place your finger on the home button.
