Is Apple going to bring a Fingerprint scanner?
For some time, reports have alleged that Apple is testing in-screen Touch ID technology using an optical fingerprint sensor. The rumors are also confirmed by one former employee, who previously worked on the Touch ID technology. So will the new iPhone 13 have an in-display fingerprint sensor?
Apple and Touch ID
Apple introduced the Touch ID feature back in September 2013 and the iPhone 5s was the first gadget that came with the new feature. It was embedded on the home button and allowed users to easily unlock the device. Apple was one of the first companies to introduce the technology that offered better security than the pattern lock, pin code, or password text. Soon, after that many companies adopted the technology.
In 2017, Apple came up with a new technology that allowed the company to replace the fingerprint scanner. That technology was the facial recognition system also known as Face ID.
Is Apple bringing back the Touch ID scanner?
So why would Apple bring back the Touch ID sensor, a technology that was dumped four years ago? Maybe it has something to do with the fact that most Andriod smartphones already come with the feature.
However, the new optical Touch ID is going to be in the form of an in-display fingerprint sensor. It will be an add-on along with the Face ID that uses a 3D scanner and neural sensor to unlock the gadget.
How does the optical fingerprint scanner work?
The optical in-display fingerprint technology captures the image of the finger when it’s placed on the sensor. The process is done using light to detect the fingerprint. This is why you will notice the screen light up when you touch the display.
However, the technology isn’t as reliable as an ultrasonic fingerprint sensor that uses inaudible sound waves. Also, the ultrasonic sensor is faster and works through dirt, oil, grime, or water.
There are other drawbacks to consider. Optical scanners have been shown to be tricked by high-resolution photos of fingerprints making them less secure. Also, if the finger happens to be wet, or dirty, it can interfere with the scanning making it less accurate.
