Refurbished Laptops With Fingerprint Scanners

A fingerprint reader on a laptop makes it easier to log in and unlock your device. It can also improve security because you don’t have to type in an alphanumeric password. Most cybersecurity experts agree that a fingerprint scanner is more secure than an alphanumeric password.

There are many different types of fingerprint scanners on laptops but they all work in fundamentally similar ways. The first step is to program the scanner by pressing your finger against it multiple times so that it can create a profile of your unique fingerprint. The software then looks for all the ridges and valleys, or minutiae, to create a digital representation that it recognises. When you need to use the scanner, it compares the current image of your fingerprint with its stored mathematical representation to decide if it is a match.

To ensure that your fingerprint is recognised every time, most scanners have a sensor, microprocessor, ARM IC or DSP and an LCD. Sensors can be optical, capacitive or ultrasonic. Optical scanners take a picture of your fingerprint using a camera. Capacitive or CMOS scanners measure the electrical currents in your finger to generate an image, and are generally more accurate than optical scanners. Ultrasonic scanners use high-frequency sound waves to penetrate the outer layer of your skin, and can detect thermal differences in between the ridges and valleys.

Although fingerprint scanning is a convenient way to login to your computer, it should be coupled with a strong password to prevent unauthorized access to your files and local data. In addition, it may not be foolproof and can be bypassed by a photograph or fake print.
