What distinguishes technology Face ID from Touch IDТехнологии protect user data is not the first year actively used in Apple technology. One technology recently celebrated its fifth anniversary, and the second there is barely more than a year. It’s time to compare Touch ID and Face ID, find the advantages and disadvantages of each of the chips.

What is Touch ID
Touch ID fingerprint scanner, which is actively used in Apple technology. For the first time this thing appeared in 2013 in the iPhone 5S. Since that time, the scanner was equipped with:

iPhone 5s/SE/6/6s/7/8
mini iPad 3/4, iPad Air/2017/2018/Pro 9.7″/10.5″/12.9″

MacBook Pro with TouchBar 2016/2017/2018

MacBook Air 2018

IPhone 5S/6/SE iPad Mini 3 and iPad Air 2 has Touch ID the first generation, the other devices got more sophisticated second generation Touch ID. The fundamental difference between the generations of no sensor, the second is considered more rapid and accurate in operation.

Fingerprint scanner integrated into the physical or virtual button on the device and reads the topography of the applied finger, comparing it with the one stored in the settings.

What is the Face ID
To replace Touch ID in 2017 came the technology of facial recognition Face ID. Special block True Depth Camera scans the three dimensional shape of a human face and compares it to existing memory.

Technology is smoooches based on neural networks in the smartphone processor. This allows the device to recognize the user even when the changed appearance with a new hairstyle, a mustache, a beard, etc.

At the moment, the Face ID is used to:

iPhone X
iPhone Xs/Xs Max
iPhone XR
iPad Pro 2018

Camera True Depth features on the face of the user a dense grid of infrared points and accurately determines the distance to each of them. So the system to model the human face.

Why do we need these technologies

Both technologies were a logical development of the banal password lock in smartphones and tablets. Instead of multiple repetition symbol combination was enough to put finger on the sensor, or look at the camera to unlock.

With the development of the operating system the Face ID sensors and Touch ID started to use to confirm purchases, and transition to protected sections of system settings and to identify some third-party applications.

At the moment, both systems are equally recognized as safe and are used for the same range of tasks in iOS. In macOS, the Touch ID sensor appeared relatively recently and the system is just beginning to acquire the features with the use of the fingerprint scanner.

Advantages and disadvantages

Each of the systems have their pros and cons. Select the device on the basis of the protection system is impractical, will have to put up with the existing system in a specific device.

Touch ID has the following advantages:

time-tested system, the modules work reliably, and repairs in case of breakdown, is inexpensive (repair Face ID much more expensive)

it is possible to use without looking at the machine, convenient to use at an angle or when the smartphone is on the table (Face ID required to comply with a certain angle between face and screen)

you can set 5 prints, which in theory allows you to make the device up to five different users (Face ID in iOS 12 taught to remember only a few individuals)

On the side of the Face ID these strengths:

a more modern protection with less chance of breaking

requires no special button/area on the device

you can unlock your smartphone with gloves

Of course, the newer technology Face ID is more progressive and interesting, unfortunately, the cupertinos are in no hurry to implement it in notebooks. Now models are widely equipped with Touch ID, to a couple of years to give the Face ID in the MacBook for the big innovation.
