One of the main problems of the optical sensor is that most of them can be fooled easily. Of course the better the camera on the sensor the better the image and better the security. The optical sensors rely on pretty much a camera, that takes a detailed photo of the fingertip and using various algorithms scans the image. Optical fingerprint sensors are the oldest off the bunch, and are still used everywhere. I will be covering the first 2, so let's start off with the optical fingerprint sensor. There are 2 main types of fingerprint sensors present today, optical fingerprint sensors, and capacitive fingerprint sensors, there is also a new type that is being developed currently, the ultrasonic fingerprint sensors. Fingerprints are a unique thing for every person, so they are now used everywhere around us, specially on phones, since the technology allowed them to get so small. Fingerprint sensors, as the name suggests, are used for identifying fingerprints.
