The Biometrics Attendance System is based on the recognition of self and non – transferable physical characteristic of the people. It is considered as the safest and most effective. It operates through the analysis of DNA, fingerprint, retina, iris, face, voice, hands, among other characteristics.
Currently, it is one of the most used by various companies, industries or public and private entities as part of their security systems. However, biometric devices have also proven to be excellent tools to bring an adequate control of staff attendance, where biometric readers of facial recognition and biometric fingerprint readers are the most used.
This technology, in addition to supporting assistance control, contributes to the good development of companies. In this article, we tell you a little more about the contribution and advantages of biometrics in personnel control. Because the identification element is a part of us and not an external element such as cards or passwords, there is no risk of loss or theft.
- Biometrics can be used in conjunction with other security systems.
- It protects people from possible identity theft.
- It does not require expensive maintenance or complex installations.
- Biometrics has innovative applications that allow a simpler and more fluid work in large corporations.
- It allows the real-time monitoring of each collaborator (control of income and outputs).
- It allows leaders to make informed decisions and avoids unnecessary expenses.
How do biometric systems work?
The biometric systems are automated identification and verification of an individual, where only certain biometric patterns that cannot be altered, tampered with , forged or stolen personal information to recreate or access information from other analyzes.
There are two basic types of biometrics:
Physiological biometrics is the most used for the control of assistance in companies, where the following patterns are analyzed:
Fingerprint: Fingerprint Time Attendance System work very effectively and quickly. They are reliable, safe and quick in identifying workers. First, they take an image of the finger. Then, the reader keeps specific characteristics of each finger analyzed and stores them in the form of an encrypted biometric key.
Facial: Through this technique, people are identified by their characteristics and facial features.
Retina: To analyze the retina, the blood vessel that is located behind the eye is verified, this allows corroborating if it is the same person. To scan the retina, a low frequency light is used.
Signature: For the verification of the signature, the way of writing, the pattern of words, among other specific characteristics is analyzed to corroborate that the signature belongs to the same person.
Voice: It includes the analysis of tone, frequency, among other specific features. Although it is not the most effective, many companies and institutions use it.
Within the biometric behavioral technique, certain characteristics of people are analyzed, such as the way of walking, brain waves, among others. This technique can also be used as assistance control, but the installation of the necessary equipment is very expensive, so it is the least used.
