FAQ - Thumb Scanner Dealers in Ashta

1. What is a thumb scanner?

A thumb scanner is a type of technology which recognizes and authenticates the unique thumbprints of an individual depending upon his/ her physiological characteristics. On the basis of these thumbprints, it allows or denies access to any computer system or a physical facility.

2. How does a thumb scanner work?

When a thumb is placed on the scanning area, a digital image of the unique fingerprint patterns is read by the in-built sensor. This digital image is then pre-processed to eliminate any unnecessary noise in order to improve image quality. The image is taken through a thumbprint algorithm to identify unique points such as ridge endings, bifurcation, island, spur, short ridge, etc. The thumb scanner generates a biometric template after post-processing the fingerprint image to store in a database.

3. What are the different types of thumb scanners?

Depending on the technique of capturing and comparing the thumbprints, there are different types of thumb scanners like:

Optical thumb scanners: These scanners capture an optical image, basically a photograph, and use algorithms to detect the unique patterns on the surface like ridges and unique marks, by analyzing the light and dark areas of the image.
Capacitive scanners: This is the most common type of thumbprint scanner used these days. They comprise of tiny capacitor circuits which collect data about a thumbprint. As capacitors store electrical charge, connecting them to conductive plates on the scanner allows them to track the details of the thumbprint. The charge in the capacitor changes slightly when a thumb’s ridge is placed over these conductive plates, whereas an air gap leaves the capacitor charge relatively unchanged. A specially designed op-amp integrator circuit tracks these changes, which are recorded by the analog-to-digital converter.
Ultrasonic scanners: In these scanners, an ultrasonic pulse is transmitted against the thumb. Some pulse is absorbed while some of it bounces back to the in-built sensor, depending upon the pores, ridges and other details that are unique to each fingerprint.
