What are Biometric Devices?

A biometric device is an electronic device for identifying and verifying individuals.

Biometrics devices have built-in sensors that use a variety of sensing technologies to capture a person's unique physical or behavioral traits, such as fingerprints, facial features, palm prints, iris scans, hand geometry, vocal patterns, human gaits, and others.

Biometric devices can be found anywhere, including:

  • Airports
  • Banks
  • Government buildings
  • Hospitals
  • Offices
  • Schools

and more.

Biometric devices are increasingly widespread; according to Meticulous Research®, the market for biometric systems (including hardware and software) will be worth $51.6 billion by 2029. From 2022 to 2029, the CAGR is 12.4%.

The growth of the biometric system market is expected to be led by the growth of biometric devices. This segment is expanding due to a growing demand for mobile biometrics devices, more attention is being paid to hardware-centric security features, and biometric technology is being used more and more in consumer electronics for authentication and identification purposes.

Types of Biometric Devices

We've made a list of various biometrics devices for you to consider as you search for the ideal solution for your requirements.

There are three types of biometric devices based on how the user interacts:

  • Contact biometric devices
  • Contactless biometric devices
  • Hybrid or combination biometric devices

#1.Contact biometric devices

Contact biometric devices are a type of biometric device that requires physical contact to collect your biometric data. This type of device is typically used to collect fingerprints or palm prints with an electronic sensor.

Contact biometric devices can be classified into three types, which are commonly found on the market, as follows:

Fingerprint scanners

Fingerprint scanners are the most common type of contact biometric devices. There are two main types of fingerprint scanners.

The first type of fingerprint scanner uses optical technology to scan images of fingerprints. It scans your fingers with LED light to find a change in the pattern of reflected light, which triggers an electrical signal that is then turned into digital data.

In another type of fingerprint scanner, capacitive sensors are used to measure changes in electrical current caused by changes in how well the skin conducts electricity.

Fingerprint scanners are a type of biometric device that has been in use for quite some time. It is an extremely useful tool for registering and verifying identity in a variety of situations, including obtaining a national ID, registering to vote, banking, registering a SIM card, protecting cyber security, and so on.

Palm print scanners

Palm print scanners are a form of contact biometric device that take an image of your palm and then use that image to verify your identification. These scanners capture an image of your palm using a optical image sensor. It works similarly to a fingerprint scanner, except it reads your palm instead.

Palm print scanners are able to identify an individual by reading their distinctive palm vein patterns and comparing them to a database of already established patterns. These scanners have been around since the early 2000s, and they are frequently utilized in locations that require a high level of security, such as government buildings and military bases.

Hand geometry scanners

Hand geometry scanners are used to identify people by measuring the size and shape of their hands.

These devices have a plat with embedded pins (pegs) that guide the position of the human hand to achieve the best results. After you place your hand, the charge-coupled device (CCD) cameras capture an image of it, which is then compared to a template stored in the device's memory. If your hand geometry matches the template, the device will unlock.

Hand geometry devices are utilized in a variety of applications, including but not limited to the following: identification verification, time and attendance tracking, and physical access control.

#2.Contactless biometric devices

Contactless biometric devices can capture your biometric data without having to touch you.

Contactless or touchless biometric devices can be divided into three types that are commonly found on the market:

Facial recognition terminals

Today, facial recognition terminals may be the most widely used contactless biometric device.

Facial recognition terminals capture your face images using specialized cameras such as HDR or IR cameras. These cameras can detect facial features such as your eyes, nose, mouth, and even skin tone. When in use, a facial recognition terminal can instantly scan your face as you pass by. Following the acquisition of an image of your face, facial recognition software algorithms are used to determine your identity based on the facial features that were caught on camera and compared to a database of previously seen faces. If a match is found, your identity can be confirmed.

During the COVID-19 period, facial recognition terminals quickly became the most common type of biometric device used for biometric access control systems. This was mainly due to the fact that facial recognition terminals do not require any form of physical contact and have a wide range of capabilities. Infrared sensors and mask detection algorithms, for example, could be seamlessly integrated into these terminals to measure your body temperature and detect whether or not that you is wearing a mask while your face is being scanned. It's an efficient solution of controlling building entries, as it can notify instantly if someone has contracted an infectious disease, making public spaces safer.

Today, face recognition terminals are becoming more widespread in public places such as airports and shopping malls to improve access control security. These secure devices enable you to access buildings or checkpoints without doing or touching anything other than showing your face and walking by, making life easy while also keeping you safe.

Iris scanners

Iris scanners are also a common type of contactless biometric device. These devices captures your iris of the eye with a near-infrared light camera to perform iris recognition. Your iris contains information that is only identifiable to you, this allows iris scanners to identify you based on the distinct pigmentation patterns (the coloration of the iris) that are present in your iris.

Iris scanners are useful for identifying people in a quick and accurate manner. These biometric devices are used as a contactless solution by a variety of organizations including law enforcement agencies, banks, hospitals, airports, government offices, border patrol agents, and others. These devices are also have been utilized for the purpose of identification in a variety of nations, including India, Mexico, the United States of America, and many more.

Palm vein scanners

Palm vein scanners are a type of contactless biometric device that capture an image of the veins in your palm by using near-infrared light to illuminate the veins in your hand (the network of blood vessels underneath palm skin). This picture of your hand veins can be matched to a database in order to confirm your identity within vein pattern recognition process.

Because palm vein scanners are accurate and don't require any physical contact with the user, they have become increasingly popular in recent years. This makes it the ideal choice for use in security applications in a wide variety of settings, particularly in places like hospitals, airports, and office buildings that require a higher level of hygiene and safety.

Retina scanners

A retina scanner is a device that emits a beam of low-energy infrared light into your eye to perform retinal scans while you look through the eyepiece. This makes an image of the tiny capillaries in your retina, which are blood vessels in the back of your eye. A biometric map can be made from this image, which can be used to figure out who you are.

There are no retina scanners on the biometric market because the technology is still new and building them is expensive compared to other types of biometric equipment.

Hybrid biometric devices

A hybrid biometric device, or multi-biometric device is one that captures and verifies an individual's identity using two or more biometric modalities.

Fingerprint, iris, and facial recognition are the most frequent biometric modalities used in hybrid devices. In comparison to single-modality devices, hybrid biometric devices have various advantages.

  • First, they can give a higher level of security since they use multi-biometric or multi authentication factors to authenticate users; it is more difficult to fake numerous biometric modalities than just one.
  • Second, because each modality can provide its own unique verification template, they can be more accurate than single-modality devices.
  • Third, hybrid devices can be more durable than single-modality devices because they can continue to work even if one of the biometric modalities fails.
  • Finally, using numerous biometric modalities can result in a larger false rejection rate because each modality has its own accuracy criteria.

In access control applications, for example, deploying a multifaceted facial recognition terminal with an embedded fingerprint sensor module to perform fingerprint recognition is a great approach to provide stronger security. It could do "1:N" identification first to identify "who you are," then add a second factor to ask you to scan your fingerprint to perform "1:1" authentication to answer "Are You Who You Say You Are?" This makes it more difficult for unauthorized users to gain access to secured areas.

Biometric handheld mobile devices, like the ones law enforcement officers use at airports or voter registration workers use at polling places, often use hybrid biometric or multi-factor authentication to identify and verify people. This makes the identification process more accurate and secure. People can use these mobile biometric devices to scan fingerprints and other biometrics to get accurate information about someone without having to take them into custody.

Overall, hybrid biometric devices provide several benefits over single-modality devices, including increased security, accuracy, and robustness.
