THIS OYINBO PEOPLE JUST WANT CHOP PPL MONEY WITH SONIC

.......

I bet local phone engineers don't know this. lol

I think I prefer the ultrasonic cos of it's speed

Ultrasonic and optical on a Tecno phone na trash

eni4real:
Which one is on Samsung A70 pls??

I want to confirm something!!!

Optical scanner. Ultrasonic are usually for high-end phones, like the ones in S10 and Note10

Xneg:


That's the physical finger print scanner.

they now have the inscreen fingerprint

Blastedholligan:
My question is which one are mostly found in smartphones? And what type does that Tecno Camon 12 uses?

Optical sensor.

I guess you've not tried it on the Phantom 9 or the Camon 12 Pro.

nice ,so much to learn from this, i wonder which one is on the camon 12

In recent times In-screen fingerprint sensor has become a trend in the Android smartphone world. There are basically two types of in-display fingerprint scanners: Optical and Ultrasonic scanner. They function the same on the surface.

But underneath, both are vastly different in terms of unlocking method and security. So we're comparing them for you to pick whichever suits your usage.

HOW DO THEY WORK?

Optical Sensor : captures the 2D image of the fingerprint and stores the data on the device. So, when you press the display to authenticate your identity, the screen lights up to illuminate the fingerprint. A tiny camera behind the display takes the image of your finger and then compares it to the stored image.

Ultrasonic fingerprint scanner : they uses very high-frequency sound. The waves are used to map out the details of the user’s fingerprint. The sensor can detect mechanical stress to calculate the intensity of the returning ultrasonic pulse at different points on the scanner, which ultimately generates a highly detailed 3D reproduction of the scanned fingerprint. This data is used to match with the existing fingerprint data on the device.

But when comparing the two side by side, the ultrasonic ones have an upper edge. The optical fingerprint scanner needs to generate a detailed 2D image of the fingerprint. As a result, it requires more press than usual on display. It’s not heartbreaking but coming from a physical scanner, it might feel slow compared to the optical scanner which might be less secure.

So which do you prefer the Ultrasonic fingerprint scanner or the optical Sensor scanner?
