Biometric device is a piece of hardware that can be used to enroll and compare people’s information; based on biometric features such as fingerprints, facial features, iris features, and palm vein features, which are captured by special sensors and then integrated into a single device with the help of algorithms that are compatible with these features.
History of Biometric Devices
The earliest concept of a biometrics device was proposed in 1858 by a British scientist, William James Herschel, and was first used in the Gumpur region of India.
Type of Biometric Device

Fingerprint identification technology is a biometric identification method with a long history and mature technology. By obtaining the unique ridge and valley images on each person’s fingertip, the fingerprint information of each person is extracted and compared by fingerprint recognition algorithms;
The two commonly used fingerprint modules are the optical fingerprint head and the capacitive fingerprint head.

Optical fingerprint scanners utilize optics (light emitting diodes (LEDs) and lenses) to capture the ridges and valleys of your fingertip. Simply put, an optical fingerprint scanner takes a picture of your finger through the lens and then parses the picture you took through a fingerprint algorithm. From there, it accomplishes the entry of people’s information for comparison
Capacitive Sensor
Capacitive fingerprint scanners are another type of fingerprint scanner that uses electronic sensors to capture the change in capacitance between two conductive plates when the fingertip is pressed down.

Palmprint recognition and palm vein recognition are both collectively known as palmprint recognition. But these two technologies are different. The lines in the palm that are visible to your eyes are palm print recognition, and the blood flow signals that are invisible to your eyes are palm vein recognition;
Palmprint recognition is based on the different characteristics of each person’s palm to identify the personnel, and now palm vein recognition technology has gradually replaced palmprint recognition.

Iris recognition is also a type of biometric device that is gradually increasing in frequency as well as place of use. Iris recognition is done by using a camera to capture the iris image, and since each person’s iris information is different, each person contains this different pattern information. Iris algorithms are also utilized to compile and parse the captured iris images to complete the comparison of the person’s information’.

Speech recognition is currently one of the lesser used biometric devices, where algorithmic pairs are used to analyze different characteristics of speech, such as pitch, tone, and frequency, among others.
Multimodal Biometric Device
Multi-modal biometric equipment is now used more a kind of equipment, multi-modal refers to you can freely choose different biometric features for use, such as selecting face + fingerprint; face + iris; iris + fingerprints, etc., and no longer a single biometric device; which includes multi-modal biometrics also includes handheld terminal equipment and access control terminal equipment. Handheld terminal equipment is convenient for you to carry, and is used in places where mobile enrollment and identification are required;
Multimodal access control terminal equipment is mainly used to recognize the authority of personnel.
How Do Biometric Devices Work?
The biometric workflow can be divided into three parts, enrollment, verification, and matching
Ghi danh:
The process of enrollment in a biometric device is the process of binding and storing the user’s personal information with biometric data. Depending on the user’s needs, the enrollment process can be subdivided into initial enrollment and re-enrollment. Re-enrollment allows you to enroll for the first time without enrollment;
Verification:
The verification process involves comparing the information you submit with the biometric trait required to perform the verification and confirming that you are the owner of that trait.
Matching:
The matching process is used to confirm that your information already exists is the system.
Accuracy of Biometric Devices?
The accuracy of the data from a biometric device has to be considered in a number of ways, the type of biometrics, the quality of the sample, the algorithmic technology used, and many other things.
You can consider it on the following levels:
- False Acceptance Rate: FAR, with lower data indicating fewer false acceptances
- False Rejection Rate: FRR, with lower data indicating fewer false rejections;
- Fingerprint recognition: FRR interval values between 1% and 1%; FAR interval 0.001% to 0.1%
- Facial recognition: FRR interval value between 1%~5%; FAR interval 0.001%~0.1%
- Palmprint recognition: FRR interval value between 1%~5%; FAR interval 0.001%~0.1%
The above interval values are just to give you a reference, the specific value will change because of the specific equipment and so on;
Pros and Cons of biometric devices
Ưu điểm
