What Is Finger Vein Recognition – How It Functions?

Being a tech-savvy is not easy because you have to get yourself updated with latest addition to the technology. New programs are being introduced every day and old programs are going away. Let’s take the example of fingerprint verification method which would soon be replaced with Finger Vein Recognition Method.

Biometric verification methods have been very effective in dealing local to cybercrimes and fraud to online scams. Security threats and issues are much under control only because of recognition methods and therefore, the technology experts have always been busy in finding better tech solutions like vein recognition after fingerprints.

Those who follow technology news might have already known about this latest sensation and without any doubt, it is another big step towards security. Lets’ put some light on finger vein recognition technology:

What is Finger Vein Recognition Technology?

It is latest biometric verification technology and it works with a recognition pattern. The veins exist under human skin help this particular method work effectively for individual recognition and identification. Each individual has a different vascular pattern and it distinguishes every human from the other.

Technology experts have taken advantage of this amazing system of human veins to develop this latest technology. In vein recognition system, an infrared light camera and off course vascular patterns are used for individual human identification purpose.

How This Recognition System Works?

Finger vein recognition machine works in the same way as a traditional finger impression verification machine. In the very first step, each individual is registered with the nationwide system of vein verification. The same data is used to verify the person somewhere else in any part of the country. Let’s have a close look at this newly introduced sensation in the world of technology:

  • Similar to the human fingerprints, the fingers have veins as well which are usually found under the skin. Basically these are small blood vessels which allow deoxygenated blood pass through the body in an amazingly natural way.
  • This is the natural process and technology experts have used this unique natural system for individual identification purpose. The near infrared rays are used through a light camera to help veins react to it.
  • The process involves placement of one finger inside an attester terminal which threw light on the veins to highlight. This is done through near-infrared light and monochrome charged coupled device (CCD) that capture veins images.
  • The hemoglobin in the blood absorbs the light from the near infrared light and makes veins visible as dark lines to the camera.
  • The image of veins is captured and kept in the database for future biometric verification. The same image is used in future for comparing with the existing image in the database.

Brief Comparison of Finger Prints and Vein Recognition Methods

You might be wondering why there is a need to create another system of biometric verification when fingerprint method was already there and working effectively. Well, let’s have a quick comparison of both systems:

Fingerprints Recognition Method Finger Vein Recognition Method
When we compare both the methods, it is revealed that the fingerprint sensors might give false acceptance as well as rejection in many cases. While the vein sensors have proven to produce much better results because the system works directly with the veins under skin.
Many users fear hygiene issues because every user is touching the same device for verification. This may cause transmitting of viruses and germs from one to another. Since vein system, a person does not touch biometric device, the chances of hygiene issues are quite lower.
A person may have wrinkles, cuts, scars, burns or various other external reasons which may cause trouble in accurate recognition by the finger biometric. As compared to the fingers, the veins are usually safer for being under the skin. These are not usually affected by the external sources. Thus produces better and more accurate results.
As mentioned above that the fingerprint device may have hygiene issues, it definitely requires regular maintenance and cleaning which may increase its operational cost as well. Vein device does not require regular cleaning and maintenance. Therefore, the cost usually remains under control.
The risk of fingerprint forgery is too high in fingerprint method because when you touch the sensor, you leave your impression and it might be copied by criminals. On the other hand, vein recognition simply works with an alive human and therefore it is impossible to misuse it.

Advantages and Disadvantages of Vein Recognition Method

Biometric verification method has been known as the most trustworthy method of individual identification and verification. However, the addition of Vein Recognition System is definitely a breakthrough in the industry. It has got various advantages as well as disadvantages but first we will discuss some of its best advantages.


1: Forge Safety  

It is reliable because it is almost impossible to be misused by the criminals. The verification devices works on veins of a living person and therefore, nobody can forget your veins images. In short, you can verify yourself anywhere without the fear of being exploited by others.

2: Health Safety

You will not have the risk of health issues because you are not putting your figure on the same device where thousands others are putting like in fingerprint method. Therefore, you can use it safely without the fear or viruses, germs and other infections.

3: Accurate Verification

There could be various external factors which may affect the overall performance of a biometric device such as growing age, external cuts, and wrinkles and most importantly weather. However, in case of vein method, the external factors can’t bring impact on results.


1: Higher Cost

The finger vein recognition technology is comparatively newer and therefore, it may cost much higher than the previous method. Due to the cost, it is not yet adopted by most of the organizations.

2: Less Common

The technology is recently introduced and thus it has not reached to most of parts of the world yet. Besides, many cultures might also reject it because it directly works with blood vessels.

3: More Concerns

Since, it uses human veins for identification purpose users might have fears and concerns about it. Moreover, the patients with arthritis might not be able to use it because they are unable to balance their hands and limbs.

Final Words

Hope you have understood about Finger Vein Recognition much clearly after reading this article. This method is the latest addition to biometric verification so it will take some time before it becomes the only trusted way of identification.
