4. Say it in more detail, the biometric turnstile is based on the traditional intelligent turnstile gate, which
adds a variety of biotechnology such as fingerprint recognition, finger vein recognition, face recognition,
palm vein recognition, and iris recognition, so as to make the turnstile gate diversified identification
methods and meet the needs of different occasions. For example, if the biometric turnstile is used for
airport security inspection, you can show your ID and boarding pass and pass through the self-service
turnstile gate. Compared with the traditional boarding process, the biometric turnstile can greatly
shorten the waiting time.
The biometric identification method is characterized by identifying the biometrics of the passing people,
with high reliability. For example, the face recognition method uses visible light to obtain face image
information. During the movement of pedestrians, the camera can actively capture the pedestrian’s
face information and quickly identify the pedestrian’s traffic authority. Biometric turnstiles in different
places use different identification methods, some use a single identification method, and some use
multiple combinations.

5. All of our types of turnstiles can integrate
with a variety of biometric devices. We can
also provide a variety of biometric devices,
such as fingerprint scanners and face
recognition cameras, and easily integrate
these biometric devices into the pedestrian
turnstile gate, Usually, there are special
customized biometric devices used on the
pedestrian turnstile gate, which can better
match and achieve more performance. In
this way, it can also save space and look
more beautiful. If you need to buy any

7. Biometric turnstile application site
Biometric turnstile is mainly used in the station, airport, subway ticket checking, and
examination, etc. This setting can effectively ensure the smooth passage of passengers
with valid tickets, improve work efficiency and save financial expenses. In addition,
biometric turnstiles are widely used in many fields, such as office buildings, cinemas,
exhibition centers, libraries, stadiums, and sightseeing attractions, which can not only
realize the efficient control of channels, but also meet the beauty and practicability of
indoor and outdoor decoration design.
Today’s airports can “face recognition” customs clearance. Subway stations have already
started “face recognition” ticket checking. Office buildings use “face recognition” to
manage attendance. Residential areas use “face recognition” to enter the gate. Face
recognition not only brings convenience to people, but also ensures the safety of entering
staff.
Nowadays, many industries use face recognition turnstiles to replace manual services to
carry out real-name authentication, which can establish efficient, convenient, fast, and
accurate management methods for the entrance and reduce the cost of manual service
management methods.

8. The use of face recognition turnstile can develop surveillance cameras from the front end and connect the collected
statistical data with the public security organs, which is conducive to the reconnaissance work, avoid and a
crackdown on criminal personal behavior, improve the safety of public places and improve the efficiency of public
security personnel in handling cases.
Airports, subway stations, customs, and other urban public transport places, the face recognition and identity ID
number city real name authentication integration, visitors self-service security check or check clearance, instead of
manual service detection, and identification speed is very fast, improve the convenience of passengers travel.
The office building is equipped with a face recognition turnstile, which can establish an intelligent office. Customers
can say goodbye to the traditional method of swiping credit cards. They can only go in and out according to the
identification face. This not only strengthens the service management of the office building, but also improves the
customer experience. Together, the company and property management can also use the statistical data collected
according to the gate to improve the management system.
The application of face recognition turnstile in the residential area makes the security mode of the residential area
more modern. It replaces the role of security personnel, identifies more accurately and without notes than security
personnel, creates a convenient and fast entry for the residents of the residential area as soon as possible, and
prevents the illegal entry of migrant workers. When the residents can’t easily find the card, don’t bring or lose the
door card with a large luggage bag, I’m also worried that if I show my face, I can enter the door. It’s very convenient
and can improve the residents’ sense of belonging to the community.
Next, we just briefly introduce two widely used biometric turnstiles, fingerprint turnstile and face recognition turnstile.

9. Fingerprint turnstile is a widely used type of biometric turnstile, but no matter which pedestrian turnstile gate has
unique advantages and disadvantages, it is just that the customer’s choice of specific requirements is different
in specific occasions in practical application. If you want more detailed information, please check out another
article: fingerprint turnstile
Advantages of fingerprint turnstile
The reason why fingerprint turnstile is used in access control management is that fingerprints are unique
features of the human body, and their complexity is enough to provide sufficient features for identification;
If we want to increase reliability, we just need to register more fingerprints and identify more fingers, up to ten,
and each fingerprint is unique;
Fingerprint turnstile is mainly used to scan fingerprints fast and easy to use; It saves time and avoids the trouble
caused by forgetting to bring the card or losing the card.
When people read fingerprints through the fingerprint turnstile, users must contact their fingers with the
fingerprint acquisition head. Direct contact with the fingerprint acquisition head is the most reliable method to
read human biometrics. This is also the main reason why fingerprint identification technology can be applied to
pedestrian channel management.

10. The fingerprint acquisition head adopted by the fingerprint turnstile can be customized into miniaturization, which is
easier to be embedded and used in combination with the turnstile gate.
Disadvantages of fingerprint turnstile
Some people’s fingerprints are difficult to image because they have few fingerprint features;
In the past, the use of fingerprints in criminal records made some people afraid to “record fingerprints”. However,
in fact, the current fingerprint identification technology can ensure that it does not store any data containing
fingerprint images, but only stores the encrypted fingerprint feature data obtained from fingerprints.
Every time the fingerprint is used, the user’s fingerprint marks will be left on the fingerprint acquisition head, and
these fingerprint marks may be used to copy the fingerprint.
It can be seen that fingerprint turnstile is the most convenient, reliable, non-invasive, and cheap biometric
technology solution at present, and has great potential for the application of all walks of life.

11. 2. High recognition degree of face recognition turnstile: for fingerprint verification or iris
recognition, an electronic device liquid level sensor must be used to collect fingerprint
recognition, or infrared induction must be used to collect retinal images. This unique
collection method is very easy for others to find and will be hidden. However, the face
recognition turnstile completely uses invisible light to obtain the content of face image
information, which is not easy to hide.
3. Non-contact of face recognition turnstile: the customer does not need to touch the
machine and equipment immediately. The system software can basically obtain the
facial image without the customer’s active cooperation, saving time and effort.
4. High concurrency of face recognition turnstile: it can carry out express sorting,
discrimination, and identification of several faces in specific application fields.
5. In addition, the face recognition turnstile is also in line with the visual characteristics,
the characteristics of “judging people by appearance”, and its advantages such as
convenient use and visualization of results. Compared with the ID number card, credit
card certification, passport visa certification, QR code picture, and IC/ID card
certification, the face recognition turnstile does not need to carry a card or valid
certificate.

12. It only needs to arrive at the spot to carry out the certification without having to lose the card or
valid document to authenticate the vehicle, and it does not need to carry out the “gate fence”.
The system software can basically obtain facial images when customers do not actively
cooperate with each other, saving time and effort.

13. What are the identification methods of pedestrian biometric turnstile? Let’s briefly introduce it.
1. Fingerprint identification
Fingerprint identification mainly identifies the operator or the operator according to the lines, details, and
other information of human fingerprint. Thanks to modern electronic integrated manufacturing
technology and fast and reliable algorithm research, fingerprint identification has begun to enter our
daily life and become a more in-depth, widely used, and mature technology in biometrics
2. Finger vein recognition
Finger vein recognition is a kind of vein recognition. Firstly, the personal finger vein distribution map is
obtained by a finger vein recognition instrument, and the characteristic values are extracted from the
finger vein distribution map according to the comparison algorithm. Through near-infrared light
irradiation, the image of the finger vein is obtained by a CCD camera, the digital image of the finger vein
is stored in the computer system, and the characteristic values are stored.
Identification mode of biometric turnstile

14. 3. Face recognition
Face recognition is to recognize the input face image or video stream based on human facial
features. Firstly, judge whether there is a face. If there is a face, further give the position and size of
each face and the position information of each main facial organ. Based on this information, the
identity features contained in each face are further extracted and compared with the known faces,
so as to recognize the identity of each face.
4. Palmar vein recognition
Palmar vein recognition is another mature technology in this field. When using the palmar vein for
identity authentication, the image features of a palmar vein are obtained, which only exist when a
palmar vein is living. In this system, the non-living palm can’t get the vein image features, so it can’t
be recognized, so it can’t be fake.
5. Iris recognition
Iris recognition technology has now been widely recognized. Iris recognition technology is more
accurate, but sometimes there will be recognition obstacles when the device scans the retina.
The biometric turnstile needs to customize the appearance and function of the intelligent pedestrian
turnstile gate according to the needs of different occasions.

15. Biometric technology is a solution for authentication
based on human body characteristics. It is also a popular
verification method applied to the intelligent pedestrian
turnstile access control system. The biological
characteristics of the human body include fingerprint,
sound, face, retina, palmprint, skeleton, and so on. The
core of the so-called biometrics is how to obtain these
biometrics, convert them into digital information, store
them in the computer, and use reliable matching
algorithms to complete the process of verifying and
identifying personal identity.
Biometric technology is widely used, especially in the field
of security. At present, the main biometric technologies
include fingerprint recognition, face recognition, iris
recognition, speech recognition, and signature recognition.
Please see the following for the analysis of advantages
and disadvantages.
Biometric technology

16. 1. Fingerprint identification
Fingerprint identification is the most widely used biometric technology, especially in the field of pedestrian access gate
prohibition and attendance.
Advantages: it has a long history, mature technology, small equipment, and low cost. It is widely used in the fields of
attendance, access control, automatic identification, etc;
Disadvantages: contact is required, and there are invasive and health problems. In addition, fingerprints are easy to
wear, and the degree of dryness and wetness of fingers will affect the effect of identity recognition;
Summary: The development of fingerprint recognition technology involves many disciplines, such as image
processing, pattern recognition, machine learning, computer vision, mathematical morphology, wavelet analysis, and
so on. An automatic fingerprint identification system (AFIS), which includes fingerprint image acquisition, processing,
feature extraction, and comparison and equivalence modules, is the most accepted product in this field.

17. 2. Face recognition
Face recognition is a very active research field in recent years.
Advantages: it has the characteristics of good intuition,
convenience, friendliness, and easier acceptance;
Disadvantages: the existing face recognition system can
achieve satisfactory results under the condition of user
cooperation and ideal acquisition conditions. However, when
the user does not cooperate and the acquisition conditions are
not ideal, the recognition rate of the existing system will drop
sharply. In addition, the user’s face changes, which will greatly
reduce the recognition effect;
Summary: face recognition includes two research fields: face
detection and faces recognition. There are four kinds of face
detection algorithms: knowledge-based, feature-based,
template-based, and representation-based. Face recognition
needs to use facial stable features for recognition. Such
algorithms include methods based on LDA, PCA, ICA, Gabor,
and feature face. At present, the research direction of face
recognition has entered the stage of 3D face recognition.

18. 3. Iris recognition
Iris recognition technology is recognized as the most accurate recognition method among the existing biometric
means.
Advantages: high accuracy, anti deception, high practicability, and no contact. The feature template is formed by
using the features of the iris region (ring, wrinkle, spot, and crown) in human eye image, and the recognition is
completed by comparing these feature parameters;
Disadvantages: iris image acquisition equipment is expensive and troublesome. However, because it has high
accuracy and can provide accurate identity, it is the first choice for effective identity verification;
Conclusion: iris recognition is an eye-related biometric with low human interference. It uses quite common camera
elements and does not require the user to contact the machine. In addition, it has the ability to achieve higher
template matching performance. Therefore, it has attracted the attention of all kinds of people.
4. Speech recognition
Speech recognition is the application of a speaker’s voice and linguistic patterns based on biological and behavioral
characteristics. It recognizes the speaker by analyzing the unique characteristics of speech, such as the frequency
of pronunciation.

19. Advantages: easy to use, large distance range, and simple installation. Only
one microphone is needed to receive the signal;
Disadvantages: low accuracy, limited application range, easy to be affected by
background noise, physical condition, and emotion. In addition, the recording of
the same person will also deceive the speech recognition system;
5. Signature recognition
Signature recognition is a biometric technology based on behavioral
characteristics. It makes identity confirmation by analyzing the handwriting of
the signature and the pressure and speed of the signature process.
Advantages: identification of different styles;
Disadvantages: a signature is related to mood, writing tools and other factors,
especially the signature can be forged and the anti deception is poor;

20. Summary: signature recognition can be divided into online
signature and offline signature. Online signature is the
collection of signature samples by handwriting pad. In
addition to collecting the coordinates of writing points,
some systems also collect data such as pressure and pen
holding angle; Offline signature is to enter a signature
sample through the scanner. Obviously, offline signatures
are easy to forge and difficult to identify. Online signature is
not easy to forge because of dynamic information. At
present, the recognition rate can also reach a satisfactory
level.
At present, fingerprint recognition is the most widely used
identity recognition technology, and face recognition has
been paid more and more attention. The innovative
pedestrian access gate identity recognition technology
mostly adopts fingerprint recognition, face recognition, and
iris recognition, which can meet the requirements of users
such as attendance and security protection, and the
biometric turnstile gate can be customized.

21. 1. User acceptance
The most important thing for all product solutions is user acceptance. For example, many users will refuse such
fingerprint turnstile on the grounds that fingerprint identification is not hygienic enough, and there are certain
requirements for identifying users’ fingers. In this case, non-contact technology has developed rapidly. Therefore,
understanding which patterns are acceptable to users is the key to deploying biometric solutions.
2. Security
Like the hidden dangers of network security, the popularity of biometric solutions has become the target of criminals
trying to destroy. Many criminals enter interactive instructions to access restricted areas or direct attacks have become
serious problems. Therefore, when choosing biometric turnstiles, we should consider the security of the biometric
turnstile.
3. Accuracy
With the maturity of technology, the application of biometrics is constantly improving, but it is still one of the most
fundamental needs of customers. To measure the accuracy of a product, there are usually indicators such as false
acceptance rate (FRR), false alarm rate, recognition rate, false rejection rate (far), etc. Although face recognition has
high convenience, its recognition accuracy will be affected by environmental light, recognition distance, and other
factors. When users change the face by means of makeup and cosmetic surgery, it will also affect the recognition
accuracy.

22. 4. Cost
Cost is a common consideration for users, especially when selecting the best and most effective identification
hardware, cost is often the decisive factor.
5. Environment
The installation environment has a great impact on the use of the product. The recognition rate of face recognition or
iris recognition will be reduced in a dark environment. Before deciding which biometric turnstile to choose, the
environmental factors must be considered, and the environment can be modified when necessary.
6. Trend
Due to the early cost and technical constraints, fingerprint turnstile is the most popular form in the market. However, in
recent years, biometrics is becoming popular, especially in the financial and prison industries. Due to the relatively
high accuracy, face recognition turnstile and iris recognition turnstile are popular in some high-end projects.
It is worth noting that these elements are only general standards, because there is no single best model in different
projects. The most appropriate biometric turnstile can be selected only by fully considering factors such as location,
environment, and application population.
