Fingerprint scanners - Access Control Products

A fingerprint reader or scanner is a type of electronic security system that uses fingerprints for biometric authentication to grant a user access to information or to approve transactions. It used to be that fingerprint scanners are mostly used in access control and time and attendance devices.
Biometrics are unique physical characteristics, such as fingerprints, that can be used for automated recognition. ... This system, called the Automated Biometric Identification System or IDENT, is operated and maintained by OBIM.

Fingerprint scanners work by capturing the pattern of ridges and valleys on a finger. ... As a finger rests on the touch-capacitive surface, the device measures the charge; ridges exhibit a change in capacitance, while valleys produce practically no change at all. The sensor uses all this data to accurately map out prints.
Fingerprint scanners are security systems of biometrics. They are used in police stations, security industries, smartphones, and other mobile devices

The main purpose of biometrics in these applications is to determine or verify someone's identity in order to prevent unauthorized people from accessing protected resources.

TAS offers a wide range of quality fingerprint readers for access control.

Fingerprint Scanners

A direct fingerprint scanner (DFS), also called a fingerprint scanner or fingerprint reader, is a biometrics device that uses automated methods of recognizing a person based on unique physical characteristics of a person's fingerprint. It works by capturing the reflected light of the fingerprint through the OLED pixels. So, when you touch the screen, the display lights up to illuminate the fingerprint. The sensor then captures a high-res scan of your fingerprint through the light reflected from the gaps between the pixels.

A fingerprint scanner performs a very basic function: it takes an image of your fingertip and compares it against the data of a previously scanned fingerprint. If the two match, then security is granted.

Fingerprint Scanners

A fingerprint scanner, also known as a fingerprint reader or fingerprint sensor, is a biometric device used to capture and analyze the unique patterns of ridges and valleys on an individual's fingertip for the purposes of identification and authentication

fingerprint scanners are integral to modern security systems, offering a balance of security, convenience, and reliability.

Components and Functionality

1. Sensor: The primary component that captures the fingerprint image. Different types include:

  • Optical Sensors: Use light to create an image of the fingerprint.
  • Capacitive Sensors: Measure electrical currents to form the image.
  • Ultrasonic Sensors: Use sound waves to produce a detailed image.
  • Thermal Sensors: Detect heat patterns from the fingerprint.

2. Processor: Converts the captured image into a digital template and performs the matching process by comparing the new scan with stored templates.

3. Storage: Stores the digital templates of fingerprints, either locally on the device or in an external database.

4. Interface: Connects the fingerprint scanner to other systems or devices, often via USB, Bluetooth, or wireless connections.

Working Mechanism

  • 1. Enrollment: Initial fingerprint capture and storage of the digital template in the system’s database.
  • 2. Scanning: Capturing a new fingerprint image when authentication is required.
  • 3. Matching: Comparing the new fingerprint image with the stored templates to verify identity.
  • 4. Access Control: Granting or denying access based on the matching result.


  • Security and Access Control: Used in buildings, secure facilities, and for personal devices to control access.
  • Consumer Electronics: Common in smartphones, laptops, and tablets for user authentication.
  • Financial Services: Ensures secure transactions and user verification in banking.
  • Healthcare: Verifies identities to secure access to medical records and systems.
  • Law Enforcement: Identifies individuals and manages criminal records.


  • High Security: Difficult to forge due to the unique nature of fingerprints.
  • Convenience: Quick and easy to use with just a touch.
  • Reliability: Consistent and generally stable over time.


  • Accuracy: Can be affected by external factors like dirt, moisture, and skin conditions.
  • Privacy: Requires secure handling and storage of biometric data to protect user privacy.
  • Cost: Initial investment can be high, but it provides long-term benefits.
