Top & Best Biometric reader: how to recognize the best options in 2022

Welcome, to! Today we are going to talk about the biometric reader. Increasingly, this device is gaining space in our day today. It is already present in ATMs, modern offices and state-of-the-art smartphones.

In addition to ensuring more security in accessing environments and / or services, the equipment gives greater control of information. You can know, for example, the exact time that your employees arrived or left your company.

In this Buying Guide, we will talk about all the advantages of biometric readers and show which are the best options on the market. Then, you can make a more assertive purchase decision.


First, the most important

  • When we talk about a biometric reader, we talk about equipment that is more present in our daily lives than you imagine. We can see technology in ATMs, next-generation smartphones and modern offices. In fact, it is already being gradually implemented by the Electoral Justice.
  • Practicality, security, easy installation and greater access control. These are the main advantages of a biometric reader. On the other hand, the equipment requires certain care. They cannot be exposed to light, especially to sunlight. Therefore, its use is limited to indoor environments. Another precaution is related to the constant cleaning of the reader.
  • Because of all the technology built into the biometric reader, it is not a cheap product. Its cost varies between R $ 500 and R $ 800.

Best biometric reader models: Our favorites

If you intend to have more security and greater access control in your office, you must understand that buying a biometric reader is an investment, not a cost. Want to know what are the best options on the market? So, check out the list below:

  • Digital biometric reader and RFID card
  • Biometric reader for more than one million touches
  • Small and versatile biometric reader

Buying Guide

The biometric reader is already more common than you think and in this Buying Guide, you will find out how this security and access control equipment works and what are its advantages. Here we go?

How does a biometric reader work?

The functioning of a biometric reader is based on the premise that each human being has unique physical aspects. The technology can be based on several characteristics of the human body, such as finger prints, irises, hand geometry and so on.

For that, it is necessary to make a prior registration. At ATMs, it is common to order digital printing. After registering, you can access your account and make withdrawals and transfers with the fingerprint only. You don’t even need a card anymore.

Home and car keys are expected to be replaced by biometric readers in the future. In this case, only previously registered people can, for example, enter and leave their apartment.

In fact, fingerprint reading technology is already common in most modern smartphones. By pressing your finger on the home button, you can access all data on the device. This guarantees your privacy.

When you install the device, you connect it to software. Thus, it is possible to have access to all the information stored in the biometric reader. Then, you can know who and when entered your office.

What are the advantages and disadvantages of a biometric reader?

To understand all the benefits of a biometric reader, imagine an office with hundreds of employees. This world of people comes and goes at different times. It is difficult to maintain control.

More: it is likely that, each day, one employee enters earlier and another leaves later. Who gets the key? Here comes the first benefit of the biometric reader.

The small device replaces the keys. With the card authentication method or digital biometrics, the equipment releases and locks the entrance door.

It is worth mentioning that the biometric reader only allows the entry and exit of people who were previously registered with their fingerprints. It is, therefore, a security mechanism. As soon as you put your finger on the reader, the device immediately recognizes your identity.

Another interesting point of the device is that it stores all the information of people passing by. Through software that records all the data of the reader, the administrative part of the office is able to know, for example, the time when people arrive and leave for work.

From the point of view of employees, the advantage is due to practicality. That’s because nobody has to carry a lot of cards or keys to get in and out of the workplace. Not to mention that access becomes much faster.

Finally, we can highlight that the easy installation of the device. You don’t have to be an engineer to finish implementing the mechanism. Just follow the manual step by step of the product and, in a short time, everything is ready!

However, the value is somewhat salty. As they are a high-tech device, readers cost between R $ 500 and R $ 800. The situation gets worse when you need to buy more than one biometric reader to install in the desired locations.

As technological as the equipment is, it has a limitation. It is not possible to install biometric readers outdoors. Direct exposure to the sun and rain decreases its efficiency and can cause damage.

From time to time, you need to clean the device’s lens. The accumulation of dirt implies reduced efficiency of the fingerprint reading. Here, the ideal is to do the cleaning with an adhesive tape.

Just apply it to the acrylic so that it covers the entire lens. Then, remove the tape completely slowly.

How much does a biometric reader cost?

Because of advanced technology, the biometric reader is not a cheap device. The price of the models varies between R $ 500 and R $ 800. Usually, the most expensive ones accept two types of authentication: by digital biometrics and proximity to a card.

Where to buy a biometric reader?

Without too many difficulties, you can buy a biometric reader on the internet. In Brazilian Amazon, for example, you can find the most varied models, from the simplest to the most sophisticated.

Among other reliable options, we can highlight Shoptime, Kalunga and Submarino. If you want a more specialized service, you can make the purchase in stores dedicated to automation, such as ZIP Automação and Automatizando.

Purchasing criteria: how to compare biometric reader models

All biometric reader models are designed to ensure more security, convenience and control in people’s access to certain environments or services. But there are some features that change from device to device. Find out what they are before making the purchase:

  • Equipment signaling
  • Authentication methods
  • Design

Equipment signaling

To notify the user if the operation was successful or failed, the equipment emits a signal. It can be via LED lighting, beep or voice message.

For example, when you position your finger in the wrong way, the biometric reader beeps twice. When the operation is successfully repeated, the beep is triggered only once.

It may seem silly, but this is an important detail to be defined before purchasing the device. If there are hearing impaired people in your work environment, it is interesting that the device also emits visual signaling.

Authentication methods

As a rule, biometric readers use fingerprints as their authentication method. However, some people have partial erasure of the fingerprint, which hinders the efficiency of the device.

So that they can be released quickly, some devices come with RFID technology. It allows authentication by both card proximity and fingerprint authentication. Typically, these models cost a little more.


How about having security, practicality and access control in a beautiful and discreet biometric reader? That would be the best of all worlds, right? So, when buying your device, be sure to pay attention to its design.

The ideal is that it is elegant and matches the environment in which you want to install. After all, you don’t have to spoil your home decor due to a security mechanism, right?
