Will the 8/8 plus be the Last Touch ID iPhone


Recently, Apple has introduced three iPhones on its launch event. Except for the iPhone 8 and 8+ which are on sale, the iPhone X is called to the most attractive and luxurious version in apple family. It will be almost $1000, so what distinguishes the iPhone X from other smartphones?

We know that many smartphones such as Samsung, Huawei and LG move their Touch ID from the front screen to the back or aside to leave users a complete screen, but Apple makes something different. Giving up the Touch ID, Apple adopts Face ID instead on its iPhone X which allows you to unlock your iPhone through facial identity scanner. Sounds a very cool technology, but does it mean that the iPhone 8 and + will be the last Touch ID iPhone? Let’s compare the two different ways of unlocking your iPhone for reliability, privacy, security and convenience.


What is Face ID?

Before we get into its merits and demerits, let’s figure out what is Face ID. In brief, it is a new technology which uses the new TrueDepth camera to create a 3D map of your face and combine with the iPhone X’s A11 Bionic processor chip to help unlocking your phone. But for the sake of security, you have to keep eyes closed so as to avoid other people unlocking your phone while you’re sleeping. Even in the dark, you don’t need to worry the access problem because the Flood Illuminator is found in the TrueDepth camera which can see you wherever you are.


Touch ID VS. Face ID

We always lack of a sense of security when comes to some new technologies. Just like we doubted for Touch ID when it was first introduced in iPhone 5s, we question Face ID’s reliability, but from what iMore testified, it seems not necessarily to worry about its security and our privacy problem. Apple also comments:

“Face ID provides intuitive and secure authentication enabled by the TrueDepth camera system and the A11 Bionic chip, which uses advanced technologies to accurately map and match the geometry of a user’s face. Face ID data never leaves the device, is encrypted and protected by the Secure Enclave.

We’ve tested Face ID on people from many countries, cultures, races and ethnicities, using over one billion images to train our neural networks and defend against spoofing.”


Although, fingerprints are another name of uniqueness, there is still a 1 in 50,000 chance that someone would be able to open your phone with their fingerprint. However this number would be much smaller when it comes to Face ID which is 1 in 1,000,000. Even though you wear glasses or hat, change hair style or have mustaches, it will recognize you.

However, compare to Touch ID, I don’t see there are more convenience on Face ID. Unlike Touch ID, we can use up to 5 fingers for registration, while we only have one face for Face ID. That means no sharing easy access with family members, friends, or colleagues. In some situation, you even have to adjust your position for Face ID to work and if your hand are filled with fruits and vegetables that would be a disaster.



Although, there are obvious merits and demerits of Face ID, it’s hard to judge whether Touch ID will be totally replace by Face ID. To a large extent, it is depend on you. If most users accept it, then why not Face ID!
