Why and How to choose fingerprint scanner

fingerprint scanner device

Currently, many companies opt ​​for biometrics when choosing the technology of time and attendance terminals. Here we explain the benefits of fingerprint biometrics.

The three primary functions of a perfect time and access control terminal are authentication, authorization and traceability. Technology providers are committed to high technology through integrated solutions that adapt to the needs of your company. Therefore the fingerprint readers of our devices are innovative tools that allow us to fulfil the functions as mentioned earlier. But why should you install them in your company?

Advantages of a fingerprint reader

The fingerprint reader system is considered today as one of the best biometric methods, one that bases recognition through a personal characteristic -in this case, the fingerprint- that can be verified in an automated way. And instant. What are the advantages of this system?

  • Avoid identity theft: each person has a unique and irreplaceable design of their fingerprints.
  • Eliminate the problems of forgetting codes and passwords.
  • The user does not need to use traditional keys, cards, … So there are no risks of losing physical identification elements.
  • It is a safe, reliable and quick verification system.
  • It is the simplest, most efficient and economic recognition of all those based on biometric characteristics.

Biometry of the Fingerprint

Fingerprint Biometrics Security

The fact that judicial bodies can collect fingerprints to identify suspects at crime scenes highlights the vulnerability of this biometric. In other words, fingerprints can be managed by a third party without consent. Moreover, when used for security applications, the fingerprint is one of the least secure identification methods, as hackers can easily forge fingerprints to fool scanners.

Accuracy

The accuracy of any biometric is measured by its False Acceptance Rate (FAR) and False Rejection Rate (FRR). The FAR measures the probability that an unauthorized user is incorrectly accessed, while the FRR measures the likelihood that an authorized user is wrongly denied access.

Privacy of Fingerprint Biometrics

Privacy is essential in biometrics because of its sensitive and personal nature. Because biometrics uses our bodies to identify us, it is highly subjective, so any biometric technology must require thuser’s’sthuser’s’s explicit consent before it can capture their biometric data.

Although the fingerprint is not as invasive to privacy as other biometrics (for example, facial recognition), it still has an essential level of vulnerability. You leave your fingerprints on everything you touch, which makes it possible for them to be collected without your consent.

Ease of Use

The benefit of the fingerprint scanner is that the vast majority of people are already familiar with it, so it requires very little instruction to be used properly.

Since palm vein biometric technology is newer, fewer people are familiar with it, and there is a small learning curve that new users will have to go through initially. New users should be taught the correct technique for scanning the palm of the hand, which involves rapid movement of th” “suspend” d” hand, but without contact on the sensor.

Best types of fingerprint readers for your business

Among the best types of fingerprint readers:

Capacitive fingerprint reader

It is a system whereby when the finger is placed on the reader, the circuit generates an electrical fingerprint that is analyzed by the device’s system. You can find it at the Secugen access and time management terminals.

Optical fingerprint reader

After placing the finger on the sensor, it is illuminated by an LED that recognizes the characteristics of the fingerprint: you can find this type of reader in Secugen time control terminals.

Fingerprint scanner and the new data protection regulation

After implementing the New Data Protection Regulation, we give you some hints of how the fingerprint readers of Grupo SPEC work. These readers automatically extract and save fingerprint points, called minutiae, during the initial employee registration process. Once these spots have been removed, immediate technical measures are applied to destroy the previously scanned fingerprint image. You should note that this process is irreversible: later, it is impossible to reproduce or obtain the original image of the fingerprint from the minutiae of a person.

Each time an employee identifies himself, the system re-extracts his minutiae and compares them with the rest of the stored template without any data transmission. The result obtained allows us to know if the previously registered user has been correctly identified or not by the system.

By the provisions of article 5.1 of the General Data Protection Regulation (RGPD), in its letter (b), it must collect personal data for” “specific, explicit and legitimate purposes. Accordingly, they may not be further processed in an incomparable way with said purpose” “. Consequently, in those cases, incomparably rise out technical operations with the minutiae extracted from fingerprint readers; these will be used solely and exclusively for the presence or access control function.

Hygienic

Another disadvantage of fingerprint scanners is that they require direct contact with the sensor to identify the user.

This makes the fingerprint perfectly acceptable for individual use, such as for personal mobile phones. However, the fingerprint creates hygienic concerns when a scanner is shared among large numbers of people.

On the other hand, palm vein biometry uses a non-contact burst of infrared light to map the internal structure of the veins, so you will never need to touch the sensor to be identified; this gives this biometry a significant hygienic advantage over the fingerprint.

This is even more important in industries requiring high sanitation standards, such as hospitals, restaurants, and food factories.

I'm working as a technician. I like to gather knowledge about new technology. And also inform others.
