Top 8 Advantages and Disadvantages of Biometric

Top 8 Advantages and Disadvantages of Biometric

In this article, you will know the answer to the query “Top 8 Advantages and Disadvantages of Biometric“.

Currently, biometrics is a technology that is used in most workplaces as an automatic authentication method.

Biometric systems come in a variety of forms, but the most commonly used are fingerprint scanners, face recognition systems, and retina scanners.

The first biometrics system can be traced back to the Chinese emperor Ts’In, who verified seals by matching fingerprints in the second century B.C.

Business owners have been greatly assisted since then by the system. As it offers enterprise security and reliability, business owners have been greatly assisted.

Top 8 Advantages and Disadvantages of Biometric

Advantages of Biometric

As well as speeding up and making authentication easier, the system has these other benefits:

1. Quicker Authentication

Businesses traditionally employed the ‘pen and paper method’, where employees signed in by pinning their signatures to their attendance sheets.

By eliminating physical attendance, the biometric system eliminates the need to perform the manual process.

To record their attendance, employees can simply use the retina or fingerprint scanner.

2. Improves the Security System

Some people have trouble remembering passwords, pins, and security codes. Passwords are no longer necessary with the biometric system.

You can use it to recognize your retina, fingerprint, or face.

As a bonus, fingerprints cannot be forged, but passwords and pins can be stolen, so the system can assist in protecting sensitive data.

3. Maximizes Convenience

The biometric system provides authentic data when employees sign in and out of an organization, which is a convenient way to track each individual employee.

As a result, Human Resources officers do not have to search through piles of attendance sheets to determine leaves, late sign-ins, and overtime.

All the information is gathered by the tool.

4. Complete Control Over Access

Human resources officers and organizations can use physical authentication to control who has access to the office building, vaults, sensitive data, and lockers.

Unauthorized personnel cannot access the facility using the biometric system. Only those who are entitled to access the facility can do so.

5. Scalability

Each organization has its own biometric system.

If the organization is launching a new department or undertaking a special project, technology can be used to enhance the process. Regardless of the size of the organization, security software is scalable.

Mobile app development and biometrics are two areas in which banks are investing! Users can sign with their smartphones using their fingerprints!

6. Flexible

Using biometrics eliminates the need to remember passwords or pins because users can use their physical characteristics.

In the present day, almost all smartphones come with fingerprint scanners that allow quick access to files on the phone.

WhatsApp, for example, offers finger recognition, which helps users keep their data safe.

7. Offers the best ROI

When compared to other security solutions, biometric authentication has a tremendous ROI.

Across a large organization, it manages all employee access and sign-ins.

Devices like these are superior to resources that would cost a lot of money to do the same work.

8. Complete Data Accuracy

Authentic and reliable company biometrics are provided by the company.

Only authorized personnel can access the biometric system, keeping intruders out.

By restricting outside access, the security of data is guaranteed once the physical trait has been logged on.

Disadvantages of Biometric

There are many advantages to enterprises from using this system; however, if you decide to use it, here are some disadvantages to consider:

1. Physical Disabilities

If even a slight change in the physical traits occurs, the authentication system does not recognize the user.

Some traits might change for the following reasons:

  • The result of burns or damage to a finger
  • Transplantation of the retina
  • Hands with tattoos
  • If the user wears contact lenses (and normally doesn’t) or vice versa

It can be inconvenient to have to change authentication methods in such instances in order to grant authorized access.

2. Expensive on the Pocket

The system is convenient and reliable, however, the cost can be very high.

Especially for small businesses, the setup, integration, and hardware for the biometric system are expensive since it hasn’t yet become mainstream.

3. Physical Traits Can’t Be Altered

Biometric systems are not perfect, just like any other system. They continue to improve.

Therefore, users are unable to rely on the safety of their data.

A person who had their identity stolen cannot alter their identity traits like they can change their passwords if their data were stolen.

4. Scanner Issues

When there is even the slightest change in the system, some biometric systems can encounter problems, especially if the company is using retina scanning.

Iris scanning is still not completely accurate due to the fact that the system will not work if the user has long eyelashes, different colored eyes, or a reflection in the corneal surface.

5. Software Malfunction

Biometric systems, which are automatic and rely on electricity for their operation, are also unreliable.

No one can enter or exit the building if there is a power outage.

Moreover, if there is a bug in the software or it fails for any reason, users lose access to the software until it is repaired.

6. No Remote Access

The system has a major disadvantage when a crisis arises, like a security breach, and HR professionals are unable to access the system remotely to remove sensitive data.

7. Security Breaches

Hackers usually steal all data in a security breach, so they can later gain access to unauthorized parts of the business.

As soon as the data is stolen, it cannot be altered and can’t be recovered.

8. Fake Positives

A hacker can make a fake positive by manipulating stolen biometric data, which is an undying cybercrime.

Biometric security is compromised by false positives, which are silicone prints made to access sensitive data of organizations.


As an innovation that is improving with the latest technology to become perfect, the biometric system can contribute to the security of enterprises. However, it’s not yet a perfect system, even though the pros outweigh the cons.
