How under display fingerprint scanner works?? Fingerprint scanners  aren’t just reserved for the very top-tier of smartphones these days, with even many budget phones packing the tech these days. Technology has moved on a lot from the early days too, becoming faster and more accurate in their readings. With all that in mind, let’s take a look at how the latest fingerprint scanners work and what the differences are.   Optical scanners Optical fingerprint scanners are the oldest method of capturing and comparing fingerprints. As the name suggests, this technique relies on capturing an optical image, essentially a photograph, and using algorithms to detect unique patterns on the surface, such as ridges or unique marks, by analysing the lightest and darkest areas of the image. Just like smartphone cameras, these sensors can have a finite resolution, and the higher the resolution, the finer details the sensor can discern about your finger, increasing the...
