Facial recognition: how it works and examples of its use in companies

Facial recognition is a biometric technology that identifies people by their facial features, making access control faster, safer and more accurate. It works by capturing and comparing images with a database. In companies, it is used to clear parking lots, restricted areas and integration with third-party management.

A facial recognition technology is transforming the way companies control access. Fast, secure and contactless, it identifies people by the unique characteristics of their face and releases entry only to those who are authorized.

More than just a modern solution, facial recognition brings more agility and operational securityIt also reduces fraud, improves the user experience and can be integrated with other technologies, such as parking release, third-party management and control of restricted areas.

Do you want to understand how this technology works in practice, its benefits and examples of its use in companies? Read on!

What is facial recognition and why is it so effective?

O facial recognition is a biometric technology that identifies and authenticates people through unique facial features, such as the distance between the eyes, the shape of the nose and the contour of the jaw.

Unlike passwords or cards, which can be cloned or borrowed, this technology is much more reliable and difficult to circumvent. What's more, it doesn't require physical contact, which makes it more hygienic and convenient for environments with a large number of people.

In companies, it has become one of the most reliable solutions for protecting critical areas, optimizing the flow in and out and ensuring complete traceability of movements.

How does facial recognition work in practice?

Although it sounds sophisticated, the process is simple and takes place in milliseconds. It is divided into four stages. Shall we get to know them?

Image capture

It all starts with capturing the image. As soon as the employee, visitor or service provider approaches the device, the camera records their face in real time, without the need for physical contact or manual interaction.

Reading and mapping facial points

The system then reads and maps the facial pointscreating a unique "drawing" of the face, with hundreds of reference points that act as a facial fingerprint. This mapping is highly accurate and virtually impossible to replicate or fraudulently.

Processing and comparison with the database

The third stage involves processing and comparison with the database. The information captured is analyzed and compared to the records previously stored in the system. This verification takes place in fractions of a second, guaranteeing extremely accurate identification.

Authentication and access release

Finally authentication and access release. If the correspondence is confirmed and the registration is in order, access is granted immediately. If not, the system automatically blocks entry and generates an alert for the monitoring center.

All this happens without cards, passwords or queuesmaking the process agile, secure and fully automated.

What are the benefits of this technology for companies?

Adopting facial recognition goes far beyond practicality. It has direct benefits for security and operational management.

Want to know the main ones? Check them out below! 

More security against fraud

The first major benefit is security against fraud. As each face is unique, there is no risk of borrowed cards or shared passwords. This ensures that only authorized people have access, eliminating common flaws in traditional methods.

Agile access flow

Another point is access flow. Identification takes place in milliseconds, avoiding queues and optimizing the time of employees, visitors and service providers. This speed improves the user experience and keeps the environment more organized.

Contactless experience

The technology also offers a contactless experienceas there is no need to touch devices or enter codes. This ensures greater hygiene and is especially advantageous in places with a high flow of people, reducing the risk of contamination.

Full traceability

In addition, facial recognition provides full traceabilityby automatically recording every entry and exit. These records are valuable for audits, monitoring critical areas and any security investigations.

Integration with other systems

Finally, the technology allows integration with other systemssuch as third-party management, parking release and control of restricted areas. This connectivity creates a complete corporate security ecosystem that is much more efficient and reliable.

This combination makes facial recognition a strategic technology for companies that need more control and reliability..

What are some examples of the use of facial recognition in companies?

Facial recognition is extremely versatile and can be applied in various corporate contexts. See where it makes a difference!

Physical access control

Restricted areas such as server rooms, warehouses and production sectors are protected from unauthorized access.

Parking clearance

Combined with license plate reading, it automatically allows authorized vehicles to enter.

Monitoring sensitive areas

In industrial or logistics operations, it tracks who has entered critical environments.

Third party management

Integrated with Rainbowtec platformplatform, it automatically blocks contractors with irregular or expired documentation. This way third parties automated and personalized management!

In all these cases, technology brings more security, efficiency and organization.

How does Rainbow offer this integrated and secure solution?

At Rainbowtec facial recognition goes beyond simple face identification. It is fully integrated with management systems and physical access controlensuring a more intelligent and reliable process.

This means that, as well as validating the face, the system checks in real time that the provider or employee has all the necessary documentation up to date. If there are any pending issues, the access is automatically blocked.

Another advantage is compatibility with existing turnstiles, gates and readersmaking the most of the company's investments. Everything is monitored in real time, with reports and dashboards that provide complete visibility and traceability of movements.

O facial recognition is a technology that combines security, agility and modernization. It makes access control more precise, reduces the risk of fraud and integrates easily with other corporate solutions.

With Rainbowtec, you get a complete, automated and reliable system to improve your company's security. Get in touch and find out how to apply this technology to your operation.
