Part 1: What is Palm Scanning Technology?

Palm scanning technology is a biometric authentication system that uses your palm veins to verify your identity.

Unlike fingerprints and facial recognition biometrics, palm scanning technology uses distinct vein patterns under users skin surface to create a blueprint for verification. It uses your internal biological traits to check your identity, creating an authentication system that is difficult to replicate.

How does Palm Scanning Technology Work?

Palm scanning technology relies on the principle that every individual has a unique vein pattern on their palm. It uses near-infrared light to penetrate your skin and illuminate its user’s veins, such that the hemoglobin within the user’s blood absorbs the infrared light and creates a distinct pattern.

Once the user’s vein pattern is captured, this system uses its advanced algorithms to convert the user’s vein pattern into a digital image that serves as a blueprint to create a unique biometric template.

The biometric template is a digital representation of the user’s palm data, such as vein pattern, bifurcation (where the vein splits), and other important characteristics.

After the biometric template is created, it is saved in a secured database, such that when a user scans their palm, it compares the vein pattern to the stored template, and if there’s a match, it grants the user access.

Where Can Palm Vein Unlocking Be Used?

Palm vein unlocking can be used in many sectors for a variety of purposes. Some of the applications include the following:

• Access Control

Palm vein biometric system cancels out the use of conventional authentication methods such as keycards or PINs that may be misplaced or even shared, preventing unauthorized access into high-security areas.  

• Hospitality & Entertainment

In the hospitality and leisure industries, palm vein unlocking can help to enhance how businesses can verify guest check-ins, ticketing, and access to special services. Its contactless nature also ensures hygiene and convenience.

• Education

It can be used by educational institutions to identify students at examinations, library access, or attendance tracking, in preventing and other critical scenarios.

• Financial Transactions

Palm vein authentication systems can be used in ATMs to verify customers' identity in ATM withdrawals and point-of-sale payments, reducing problems such as card skimming, phishing, and identity theft.

• Border Control & Immigration

Palm vein unlocking will also help in mitigating document fraud, improving security, and reducing queues at immigration borders.

Advantages of Palm Vein Scan

• High Security

Palm vein scan uses a biometric system that is highly encrypted. Since vein patterns are internal and invisible,  this authentication system is almost impossible to replicate or forge, providing a level of security far superior to external biometrics.

• Contactless Technology

Unlike traditional biometric verification like fingerprint, Palm vein scanning uses a non-intrusive, contactless method to authenticate user identity, making it hygienic and convenient. This is very valuable in healthcare and hospitality.

• Accuracy and Reliability

External factors like cuts, dirt, or moisture do not affect the scanning process in palm vein unlock. This is because vein patterns are unique to each individual and remain stable over a lifetime.

• Ease of Use

Palm vein scanners are simple to operate, requiring users to hover their hands over the scanner for quick verification. This makes them user-friendly for a wide range of applications.

Disadvantages of Palm Vein Scan

• Expensive Cost

Palm vein unlocks are expensive to develop, install, and maintain due to their sophisticated hardware and software. This could limit their adoption to industries that can’t afford the investment.

• Bulky Hardware

The size of palm vein scanners can be a challenge, especially for integration into compact devices like smartphones or small-scale systems.

Part 2: Other Types of Biometric Authentications 

Let's take a look at the other types of biometric authentications to understand how they differ from palm vein unlocking.

1. Facial recognition

Unlike fingerprint locks, face recognition is a biometric authentication system that identifies people by the distinctive characteristics of the face. This system makes use of cameras with infrared sensors that take pictures of the main facial features of a person: the distance between the eyes, the shape of the nose, and the contours of the jawline.

This security system in biometric authentication is very common in the latest smartphones, airports, and law enforcement. However, it is also prone to the lighting conditions, angles, or even facial changes with age and medical conditions.

2. Voice recognition

Voice recognition, on the other hand, listens for the peculiarity of a person's tone, pitch, even accent as an identification authentication. This voice recognition finds applications in telephone customer services, smartphones, and virtual assistants such as Alexa and Siri.

It is non-intrusive and simple-to-operate, but its reliability can be impacted by noise in the environment, voice changing due to illnesses, or even the imitation of voice.

3. Iris recognition

Iris recognition is a biometric authentication that scans the unique patterns in the colored part of the eye to authenticate individuals.

This biometric verification system uses cameras to capture high-resolution images of the iris, mapping its intricate patterns. These patterns are then compared to stored iris templates to verify identity. Because irises are unique, even among identical twins, iris recognition offers a high level of security. This method is commonly used in high-security areas like airports or government buildings due to its accuracy and non-intrusiveness.

However, it’s less commonly used in consumer devices because it requires specialized equipment.

4. Fingerprints

As the widely used biometric authentication method, fingerprint unlocking is based on the structural pattern made by the fingerprint of an individual. It basically works on optical or capacitive sensors that click a highly defined picture of the ridges and valleys at the surface of the finger. In simple words, when the finger is placed upon the scanner, it reads this particular unique pattern and then digitizes the code. This code is then matched against the pre-registered fingerprints in the system.

However, fingerprints deteriorate due to injuries or wear and tear over time, and they are susceptible to spoofing.

Palm Vein Unlocking vs. Fingerprint Lock: Which is Better?

Palm vein unlocking and fingerprint lock are two powerful biometric authentication systems that offer secure and convenient ways to verify identity. But have you ever wondered which is better between these two?

If your answer is yes, you're not alone.

Both systems rely on unique human traits, but their technologies, applications, and benefits differ significantly. See the table below;

FAQs

How Accurate is Finger Vein Recognition?

Generally, finger vein recognition is very accurate, often with an accuracy rate of more than 98.45%.

The reason behind this technology is the structure of veins beneath the skin's surface, which is quite hard to replay or forge. It captures the patterns using infrared light, making it rather reliable in several instances, such as when the skin is dirty or sweaty.

Vein recognition technology also has less tendency to give out false positives or false negatives, compared to fingerprint scanning, because the vein is inside and hence not influenced by external circumstances such as scars, cuts, or dirt covering it.

What is the Difference Between Finger Vein Recognition and Fingerprinting?

The major difference between finger vein recognition and fingerprinting is the captured biometric data.

While fingerprinting uses the external patterns of ridges and valleys present on the surface of the finger, Finger Vein Recognition detects the pattern below the surface in infrared light that depicts the flow of blood underneath the skin's surface.

Also, unlike fingerprints, finger veins cannot be affected by such factors as dirt, cuts, or wear; thus, they are more accurate and less vulnerable to spoofing. So does palm vein unlocking.

Is Palm Scanning Technology Safe?

Among the safest ways of biometric authentication today is palm scanning authentication - the fact that it uses vein patterns in the palm makes it extremely difficult to forge or replicate.

In addition, the technology is contactless, hence ensuring hygiene and reducing the risk of contamination in shared spaces.
