Contactless Biometric Identification From Hitachi

May 5, 2021

There has been the possibility to use the finger as a form of recognition for some time, but now it is quicker and easier. It used to be the case that the finger had to be pressed onto the device for it to be read. While this was not a big problem, it did take a little time. There were times when it may have seemed the odds of being accepted the same as when playing ruletka online, but recently, there have been big improvements. 


Passwords and swipe cards were once enough to ensure things were secure, but as time moves on, there is the need to upgrade. Hitachi, which is a Japanese company, has taken this technology a step further. There is no need for the person who needs to be identified to stop and touch the reader. At present, when it is known that Covid-19 can be spread by touching infected items, this is particularly good news.

It is considered that the ideal place for this technology to be used is in airports. People are often rushing to catch a flight, and the last thing they need is to be stuck in a queue, realizing that they are likely to miss the plane. It can deal with a high volume of users, and sports stadiums will also benefit from them.

How It Works

All that the user needs to do is place the hand in the area, and the scanner will be able to read the veins. This technology involving veins is already in use, but Hitachi has expanded on this. It is thanks to this that the process has been speeded up. It does not even matter how the hand is presented. The position of the finger does not matter, it will be read, and if it is recognized, it will be able to pass through. 

The days when there had to be a single finger used, and it had to be kept still, are long gone. A Hitachi spokesperson explained that the lighting was controlled in such a way that the finger was lit up regardless of the position or angle it was in. This allows for speed and prevents queues.

Why Are Veins So Important?

The new biometric technology is more secure than previous ones. Even though it is still the finger that is being used, there is a great difference between scanning a fingerprint and finger vein authentication. It is not just the ridges of the finger that are being checked, but the blood in the veins. This is a better system because:

  • It is not possible to fake the veins as they are internal vessels.
  • Fingerprints can alter over the years, but veins in the finger do not.
  • There is no need to touch the scanner when viewing the veins.

The person being scanned must be alive and present. It may seem strange that this is an improvement, but it would be possible to scan a recently severed finger when prints only were needed.
