In 2022, the biometric systems market worldwide was worth about $42.5 billion. By 2027, this number is expected to almost double, reaching $82.9 billion. Such rapid growth can be explained by biometric solutions becoming an indispensable part of the professional services industry, particularly in finance and banking. People prefer this verification method because of its ease of use, time efficiency, and high protection level.
As of now, biometrics in banking is one of the most reliable security solutions, considering that each person bears unique biometric characteristics. In this article, we will look at the essence of biometric authentication from the technical side. Whether you are a business founder planning to integrate this feature into your application or a finance & banking representative striving to learn more about this notion, we have a lot to share with each of you.
Keep reading to learn what biometrics authentication in banking is and how it facilitates user experience.
What Is Biometric Authentication?
Biometric authentication is one of the security measures that leverages people’s biometric characteristics to check the user’s authority and identity. The biometric characteristics can include fingerprints, facial characteristics, voice or retina characteristics, etc. The data on these characteristics is recorded by technology and stored in the database.
To log into an application or perform some operation with the help of biometrics in banking, a person has to use their biometrical data to verify the identity. The system will scan the data with scanners suitable for the given data type. The scanner will check if the presented data corresponds to the data in their database recorded initially by a user. If the match is successful, the user will get permission to proceed with their actions.
Biometrics authentication is a highly secure and innovative method that has a lot of benefits. The biometric data is usually encrypted and stored on the remote server. In contrast to traditional methods like passwords that can be guessed or ID cards that can be lost or stolen, biometric authentication in banking uses people’s unique characteristics as the power to differentiate them and protect their data.

Biometric security types
We can differentiate between 3 major categories of biometric security. These include:
- Behavioral. This type of biometric data captures the behavioral patterns of a person. An example of behavioral biometrics is the handwriting pattern.
- Morphological. Morphological biometric is the term denoting physiological peculiarities each person has. For example, a particular voice structure or fingerprints.
- Biological. This category covers biological material like blood, hair, or saliva used to check one’s identity usually applied in criminology. In common life, this method is not used because of the time inefficiency and discomfort for a client.
Top 5 Biometric Authentication Methods
There are various mobile biometric authentication methods that people use daily on their devices, from facial and speaker recognition to finger geometry or retina scans. Let’s discuss each type.
This type is based on the work of convolutional neural networks (CNN). At first, CNN creates a face template based on the scanned data on the user’s face features, including nose, eyes, and mouth. Then, at each attempt, CNN compares the new data to the template and allows a user to proceed with their action in case the match happens. Here is more about this method:
Signature recognition techniques can be static or dynamic. For static signature recognition, the technology will record the result of your signature and compare your next signature to the initial copy. For dynamic signature recognition, the technology will focus on the process instead of the result. It will record the patterns, timing, pressure, etc. of your writing and compare the next copies to this template.
Under this method of biometric authentication in banking, the technology scans the user’s retina or iris. Retina scans are more precise and take more time to complete compared to iris scans. The drawback of such a method is that the scans should be performed from a very close distance, which may be uncomfortable for users. However, the manufacturers of smart devices are now trying to make this method easier to use.
Each person has a unique fingerprint ridge, also used in biometric security techniques. For fingerprint scans, the system first records the data on the user’s fingerprint ridge as a template. Then, all a user has to do is place their finger at a scan and hold it for a second or few. It’s important to use the same finger the data on which has been stored in the template.
The voice recognition technique is based on collecting data on one’s speech and voice, including pitch, accent, and speed. Voice recognition is implemented for security purposes, voice search, and even assigning commands to smart devices.
So, these were the top 5 methods of using biometrics in banking. There exist some other, less common types, including vein recognition, gait recognition, and finger geometry. For vein recognition, a hand vein scanner is applied. In the case of gait recognition, the technology studies a person’s speed, style, and angles when running or walking and uses this data to create a template. Finally, for finger geometry, biometric scanning technology scans the form, structure, lengths, etc. of fingers, usually in three-dimensional imagery for better accuracy.
Biometric Authentication in Banking: Application and Benefits
One of the most common applications of this technology is the use of biometric authentication in the finance and banking sectors. For financial entities, biometric authentication is the means of ensuring security and convenience for their clients. With the rise of mobile banking, this security method has become even more widely used.
Typically, mobile banking apps leverage biometric authentication scanning with the help of mobile phone cameras or sensors. Among the most popular types of biometric authentication in banking, we can mention facial mapping, fingerprint identification, and voice recognition. They are used for the following purposes:
- Verifying and using bank accounts. To confirm their identity, clients can use biometric authentication, which eases the process of logging into the bank account, opening a banking app, confirming changes in the app, etc.
- Confirming financial operations. A biometric authentication app can be used to confirm financial operations like money transfers or online payments. Instead of typing in the identity data manually, a user can choose the biometric authentication method to complete the action in a few seconds.

Top-notch operation security
When it comes to money operations and transactions, security is a top priority that can be well ensured with biometric authentication practices. All clients’ sensitive data and confidential data of a business are well protected. It’s extremely hard to fake the unique biometric characteristics of each person, which is why leveraging biometrics for banks is a good way to eliminate the risks of identity fraud.
This benefit is tightly connected to the previous one. As biometric authentication relies on the unique physical traits of each person, using this authentication method is always available for a client. Anytime, they can scan their face or fingers and get access to the banking services they need. This, in turn, saves a lot of time and makes the user experience more pleasant.

Ease of use
Biometric authentication is simple and easy to use. When it comes to traditional security measures like using passwords, people often forget them and lose access to their financial accounts. With biometrics data, such cases cannot happen, as the identity proofs are literally “always with a client.”
5 Components of Biometrics in Banking
To implement biometric authentication in banking, you will have to incorporate the key 5 components:
Mind these components at the project planning stage because each of them will require effort and attention from your software engineering team. Let’s look at what stands behind these components.
Mobile biometric authentication is a preferable method for confirming a person’s identity. However, it shouldn’t be the single method implemented by a company. Some problems with scanning may occur, and a user will need to use alternative methods. Thus, you should implement multifactor authentication in which different methods are available, including password checks, the confirmation of the user’s data, etc.
Integration of APIs
If you partner with other companies, you will also have to build a financial API allowing them to easily use the mobile biometric authentication method leveraged by you. It will simplify the implementation of your services and ease cooperation with other companies.

As the number of mobile users increases, more and more services are shifted to mobile and require profound protection. This is why you should also care about the mobile security of your banking solutions. For this, implement advanced mobile security measures like debugging protection, root detection, anti-hooking, and others.
Transaction data signing
Transaction data signing is a part of the authentication process that generates the encrypted code to confirm user action. Such a method is obligatory for sensitive operations. For example, for transfers where big sums of money are involved or when the user requests a change in personal data.
The implementation of biometrics in banking should comply with the rules and regulations imposed by the organizations governing the finance & banking sector. Among the most important regulations to follow, we can mention FFIEC (Federal Financial Institutions Examination Council), PSD2 (Payment Services Directive 2), and NIST (National Institute of Standards and Technology).
