What is Fingerprint scanner or sensor in mobile? 

Fingerprint sensor 

Fingerprint scanner is a type of technology that identifies and authenticates a person's fingerprint to allow or deny access to a mobile phone system or physical facility.

This is a type of biometric protection technology that uses a combination of hardware and software techniques to identify a person's fingerprint scan.

How works Fingerprint scanner.

There are three types of fingerprint scanners. 

1. Optical scanner
2. Capacitive scanner
3. Ultrasonic scanner 

Optical Fingerprint scanner. 

It is the oldest type of technology digital scanner used to capture and compare a person's fingerprints. it is a sensor that uses an optical image capture technique, along with the use of algorithms, to detect unique patterns on the surface of the finger, including crests or unique marks, all through an analysis of the light and dark areas of the picture. 

Capacitive Fingerprint scanner. 

It is the most common type of fingerprint sensors in smartphones, which accurate use a capacitive scanner. Unlike the previous technology, with capacitive fingerprint scanners, instead of creating a 3D image of a fingerprint, tiny capacitor circuits are used to collect fingerprint data. Because capacitors can store an electrical charge, by connecting them to the conductive plates on the sensor surface, a traceable trace can be tracked digital.

Ultrasonic fingerprint scanner. 

It can be this is the latest technology used in fingerprint sensors, in which to really capture the details of a fingerprint the hardware consists of a receiver and an ultrasonic transmitter. What does it do, an ultrasonic pulse It is transmitted on the finger that is placed on the sensor. Some of this pulse is absorbed and part of it is recovered by the sensor depending on the crests, pores and other details that are unique in each fingerprint.
