FAQ - Thumb Scanner Dealers in Delhi

• 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.

• 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.

• 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.

• What is the price of a thumb scanner in Delhi?

  The price of thumb scanner can depend on various factors like brand, certification, type of sensor, waterproofing, etc. Bulk orders can lower the thumb scanner price. You may contact our listed security system dealers in Delhi for more details.
