The Touch ID fingerprint recognition system appeared in 2013 with the iPhone 5s. It was the first time that an Apple device integrated another type of protection beyond the classic numerical code. The user could register several fingerprints to unlock the terminal with different fingers. It was such a degree of acceptance that the company moved it to the iPad and the MacBook with Touch Bar.
However, with the iPhone X was unlocked by facial recognition, named Face ID. A safer and faster system than the Touch ID capable of working in many situations and that was sweat-proof hands. However, it has some drawbacks with certain types of glasses that can be solved.
Although some rumors claimed that the smartphone of the tenth anniversary would also include the unblocking by footprint, it was not implemented. It seems that Apple had problems placing the Touch ID under the screen, something that other manufacturers have managed to do successfully.
Face ID is also available in the new iPad Pro 2018, and everything seems to indicate that it will reach the Mac in the future. However, Apple keeps spinning the Touch ID under the screen, doing research to possibly bring it back on future devices.
Apple wants Touch ID to be available on the entire screen
The Cupertino has published a patent called “Acoustic pulse coding for images of input devices. ” According to AppleInsider, it describes the way in which sound could be used on a surface to detect objects that approach and make contact with it. In other words, when we put our finger on the screen the device will detect it and be able to “read” it.
This technique would have many benefits, including reducing the thickness of the components needed for fingerprint recognition. Also, it would be faster to process the request and it would not need so much energy to function.
