Last updated on: May 7th, 2023 13:10 pm

What is QR code turnstile?

QR code turnstile is a kind of pedestrian turnstile gate that uses QR code recognition to control the pedestrian turnstile to open the gate. In more detail, the QR code scanner is embedded in the pedestrian turnstile gate to open the gate. QR code turnstile uses the QR code scanning method to open the gate and achieve the purpose of controlling personnel access.

The security performance of the QR code turnstile is very high, mainly because it can realize data management, every time you use it, the access information will be recorded effectively, making the data management easier and more accurate. This can not only reduce the pressure on staff, but also greatly improve the security level of scenic spots, subway stations, houses, office areas, and other application places, and the efficiency of opening the gate by scanning the QR code is very fast.

In recent years, with the continuous demand of the security market, convenient carrying, and acquisition, QR code has quickly become one hot spot in the industry of turnstile gate recognition.

Integrate with ticketing system

Turnstile gates are access control and blocking devices used to manage the flow of people and regulate pedestrians in and out. Nowadays, with the rapid development of the market economy, the demand for turnstile gates is increasing day by day. Turnstile gates have been set up in various scenic areas, office buildings, factories, and station entrances and exits.

However, a complete set of access management devices can be completed not only by turnstile gate machines, but also by combining the access control system, turnstile gates, and QR code scanning equipment are jointly completed, and the turnstile gate can interface with different ticketing systems. Therefore, paid and non-paid areas are also formed in different places, and pedestrians are allowed or prohibited to enter or exit according to different permissions.

Next, let’s use a video to make a simple description:

This is a QR code turnstile, ticketing turnstile gate in the video. The clients have their own QR code generation platform. They will provide the QR code to their members. The members will take tickets with the QR code to operate at our turnstile gate. They have an API built out which can take QR codes and provide a response if the gate should open or stay closed. They provide the API of the system and QR code to us. Our IT people use postman to test the API call.

After several tests, we called the API successfully. And our IT people do the integration of the client`s system with our ticketing board. This video mainly shows how the QR code system works with the turnstile gate.

How does QR code turnstile work?

Next, we are going to talk about how does QR code turnstile work? (The principle is not complicated)

QR code turnstile gate is opened by connecting QR code scanner embedded in the turnstile gate to the door opening signal of the turnstile gate. The personnel gets a QR code through software authorization, takes the QR code, and scans it on the turnstile gate to realize the door opening state. The QR code without authorization cannot pass through the turnstile gate. It is the same as swiping an IC card ID card, but the card is replaced with a QR code. The card reader was replaced with a QR code scanner.

If the RFID card reader and QR code scanner are added together on the turnstile gate, the scanning QR code and card swiping can be used together at the same time. If you want to know more details about turnstile gate with card reader, please check our another article: turnstile gate with card reader

In the related technology, in the campus, the amusement park, the subway station, and so on management, in order to realize the personnel flow control, generally sets the turnstile gate at the entrance and exit, one kind of swipe card type gate, needs the magnetic card to carry on the identification, the magnetic card processing is complex, the cost is high, and carries inconvenient, easy to lose, has brought many inconveniences to the user.

In addition, the turnstile’s switch circuit of the existing gate is complex, the cost is high, and it is easy to break down, which affects the access of personnel.

In view of the shortcomings of the existing technology, Mairsturnstile proposes a gate control system based on QR code turnstile scanning recognition, which is based on QR code information recognition. It solves the problems of high cost and inconvenient use of the existing swiping card turnstile ; 

The turnstile gate switch adopts an electronic switch, the circuit is simple, the opening and closing efficiency are high, it solves the problems of the before existing turnstile gate is complex, high cost, and easy to break down.

Advantages of QR code turnstile:

With the continuous development of the social economy, QR code access control turnstile machines are increasingly widely used. In order to better improve the safety factor, QR code access control turnstile gate is also increasingly widely used in daily life. What are the specific advantages of the QR code turnstile? Let’s analyze it together.

1. Fast recognition speed: The recognition speed of the code-scanning turnstile gate can basically reach 0.2-0.3 seconds, greatly reducing the waste of time when passing through the turnstile gate. Scan the code to achieve immediate passage without queuing for registration, saving time.

2. High security: Prevent unidentified persons from entering relevant areas to ensure environmental safety.

3. Simple and easy to use: The QR code turnstile gate embodies intelligent visitor management: it not only simplifies the registration process, but also enables one-stop service. At this stage, the QR code turnstile can only be used through simple training and learning, and maintenance can only follow a few simple operating procedures to find common problems, which can be quickly, conveniently, and quickly eliminated.

4. Good visitor experience: The QR code turnstile verifies whether the ID card is uniform, identifies the authenticity of the ID card, scans the code to verify the registration of identity information, and opens the access control of the channel gate. This not only provides a good user summary, but also is efficient and convenient.

5. Multiple entry data coordination: Data can be statistically stored, multiple entry management, access records can be queried at any time, and work efficiency is improved.

6. Excellent technology: Using the current popular network management system, the QR code management method ensures that your intelligent management is not outdated for ten years.

7. Comprehensive cost reduction: From the perspective of installation, adjustment, and cabling, TCP/IP transmission can reduce many investments, and the infrastructure project cycle is short, saving cable and labor costs, and making it very easy to maintain. Therefore, the QR code turnstile has more advantages in cost.

8. Convenient expansion: The computer and intelligent management system adopt wireless communication, and the QR code turnstile can freely expand the number of safety exits.

9. Create a high-end corporate image: Intelligent QR code turnstile gate management, highlighting the corporate image.

10. Diversity of QR code turnstile identification:

When we scan the code to pass through the turnstile gate, because the complex QR code is significantly higher than credit card and NFC payment, when used in many situations, the turnstile gate usually embeds credit card, visitor, and other modules into it, which can identify the turnstile gate in many ways, in order to avoid inconvenience in one way of identification, while the other way of identification can also be used for identification, which further improves traffic efficiency.

Due to the popular trend of QR code payment, the installation of QR code turnstiles in scenic areas has driven the application and development of various industries. In the access control turnstile gate industry, the application of QR code technology is only one module, which has brought a new market for the development of access control turnstile gates and has been widely used.

QR code access control:

QR code access control is a new generation of intelligent products upgraded on the basis of traditional access control, combining traditional door-opening methods with new door-opening methods such as QR codes, ID cards, Bluetooth, and so on. The most commonly used function at the turnstile gate is the QR code and ID card door opening function, which can be understood by those who often take high-speed trains or subways, or those who love traveling. QR codes and ID cards are applied to human access doors due to their flexibility and uniqueness, How to install a QR code scanning device for the turnstile gate?

At present, the QR code access control that we commonly encounter can be generally divided into the following types according to the output format of the signal: Wigan type output, window type output, and USB type output. We only need to connect the corresponding output signal to the turnstile control motherboard to complete the docking between the QR code access control system and the turnstile gate.

According to the actual situation of the customer, it is common to use a QR code card reader or a QR code access control all-in-one machine to connect the turnstile gate. The difference between the two methods is whether an access control controller is required. If the customer has an access control controller, only one QR code reader is required for connection. If there is no controller, an all-in-one machine integrating the QR code reader and the access control controller is required for connection. These two methods can also be selected according to the customer’s wishes.

The security performance of QR code access control is very high because it can achieve effective data-based management. Every time you use it, access information can be effectively recorded, making access control easier and more accurate. This can reduce the pressure on management personnel, greatly improve the safety level of the passage, and make the passage more efficient.

QR code scanning module:

Due to the fact that most of the turnstile gates are located outdoors, we can call it ” outdoor turnstile ”, most have a sunshade, and a few directly do not, the integrated QR code module of the turnstile gates requires very good environmental adaptability.

Firstly, it is waterproof, secondly, it has low power consumption and low heat generation, and also needs to adapt to scanning code under strong light.

Do you have good environmental adaptability for the turnstile gate integration module?

1. Protection level: If the optional QR code module for outdoor use requires the overall protection level to reach IP54 or above, including the integrated design of scanning window, fuselage (upper and lower cover junction), fuselage and wire interface, and wire itself. If it is used in indoor passageways, it is only necessary to select a waterproof surface cover.

2. Strong light adaptability: Since the gate is placed outdoors, there will be strong light interference. In order to improve the user’s code scanning experience and reduce the interference of strong light on the code scanning module to scan the barcode on the phone screen, the camera of the code scanning module needs to be specially tuned for sensor parameter settings such as exposure, automatic gain, and strong light suppression.

When purchasing a QR code module, it is necessary to perform a strong light code reading test that simulates a real scene on the sample, and also to test whether the dark environment can normally trigger scanning.

Reliability of QR code scanning module:

1. As the QR code module is a peripheral accessory that requires a power supply from the main board or external connection, it is necessary to perform special power supply processing on the hardware circuit and embedded software logic of the QR code module.

That is, if the module itself encounters power supply instability, such as a 5V power supply requirement, but the actual voltage fluctuation causes the voltage to be pulled down to 4.4V, whether it can be used normally, and if it cannot work if it is lower, whether it can automatically restore to the working state after the voltage returns to the normal range, without downtime or damage. In addition, in terms of electrostatic protection, anti-electromagnetic interference, and other aspects, from device selection to circuit design, have special treatments been made.

2. The QR code module includes low-level drivers, image processing, decoding algorithms, application menus, and other parts of the embedded software. The embedded software includes a large amount of software code development and writing workload. Therefore, the writing quality and code testing of the software framework and various modules need to be mature and reliable, so as to ensure long-term stability and reliability in use. This requires selecting and judging whether a supplier’s product launch time, technical research and development, and engineering testing are professional.

Confirm that the QR code module supplier has a complete pre-sales solution, project integration, and after-sales technical support team.

As the QR code scanning module is a component integration that includes technologies such as optics, software, and hardware, and turnstile gate manufacturers do not necessarily have professional technical knowledge of the above knowledge, it is necessary for the module supplier to have a professional pre-sale, product, and R&D team to conduct professional integrated discussion and evaluation of the overall solution based on customer scenarios to prevent structural design, assembly process Problems in integration details lead to various technical and quality issues in the implementation of the project.

QR code turnstile classification:

A QR code turnstile is an ordinary intelligent pedestrian turnstile gate integrated with a QR code system. The turnstile gate is embedded with a QR code scanning module to realize the way of scanning codes through the gate, which is one step smarter than the ordinary turnstile gate with card reader.

QR code recognition:

At the present stage, the QR code recognition we usually touched is divided into the following several classifications, which is also distinguished from the output format of the signal:

 1. Wiegand signal output;

 2. Serial port signal output;

3. USB signal output;

Among these three kinds of output, USB output is more common in the application of two-dimensional code, Wiegand signal is less (Wiegand signal is often used for access control), the serial port signal output is widely used in embedded (professional hardware). So How does QR code turnstile work and what are the features of QR code turnstile?

The above is a brief introduction of QR code turnstile recognition, the specific principle of signal differentiation, we don’t offer too much explanation about this.

I noticed that actually, the QR code with Wiegand output which only in the access control industry has the application, in other industries application is very few. Why does this happen now?

Let’s take a look at the QR code turnstile access gate’s control panel.

A red circle part (WG1/WG2) in the picture is the Wiegand output signal because our swing turnstile gate is usually used for swiping card recognition.

Using QR code to identify is to modify the signal output of the QR code scanner to Weigand interface output. This scheme is very economical compared with the dedicated industrial control computer, but it involves a problem of QR code generation and distribution.

There is content in each QR code. How to generate the irregular QR code, print it or share it with the mobile phone, and then give them authority to open the gate, the problem of QR code generation and distribution. (This problem can be solved through secondary development docking at this stage.)

Looking back on the development of intelligent turnstile gate access control, the iteration of new technology gives birth to different forms of access control, from birth to now can be divided into password access control-card access control- biometrics access control-mobile phone access control-fusion access control. The emergence of mobile phone access control is a milestone recognized by the industry. It breaks the ability boundary of the original access control. Through the smart medium of mobile phones, intelligence will be brought to the extreme, among which the most representative is the QR code access control.

Working principle of QR code turnstile:

In short, the QR code reader reads the QR code containing personnel identity information. The QR code reader will encrypt and convert the QR code into digital form and transmit it to the turnstile controller through the Wiegand protocol. At this time, the turnstile controller will judge whether it is an authorized person by comparing the previously entered personnel information. If the matching is successful, Then the turnstile controller will execute the unlocking command to open the QR code turnstile gate, otherwise, it is the opposite.

The QR code turnstile gate is to embed the QR code scanning head in the gate and uses the QR code scanning to open the gate to control the staff. Like swiping an IC card or ID card, and If adding a card reader and scanning head together, then can scan the QR code and swipe IC or ID card together.

The park QR code turnstile intelligent gate is embedded in the QR code scanning head, combined with the QR code electronic ticketing system, the integrated scanning code ticket function module not only enriches the tourism service level but also improves the tourist experience. So that the park to achieve intelligent management has taken a big step forward.

Features of QR code recognition

Following we will check the features of QR code recognition, let’s go to know it again.

The accuracy of QR code recognition is 100%.

For face recognition access control system, it is synonymous with advanced technology access control in our general consciousness, but face recognition’s accuracy can not reach 100%. Because the face system is judged by comparing face features, because the face information collected through the camera can not be 100% the same, the system intelligence thinks that you are “very similar” to a face in the feature library. You will be judged to have access. Please note: I used the keyword “very similar” rather than “yes or sure”.

On the other hand, the QR code turnstile access control system, its recognition process essentially analyzes the QR code, which belongs to the digital picture of machine identification. The two colors of the QR code represent the “0” and “1” of the computer language respectively.

Therefore, the access control system can accurately identify the information on the QR code, once successfully identified, the accuracy can reach 100%. If the information of the QR code is incomplete because of the light reason or the QR code information, it will be indicated that it can not be recognized, but after the face recognition system is successfully recognized, it may appear that it is not himself.

The authority of QR code access control is flexible and controllable.

We know that there are two forms of QR codes: static and dynamic. The content of the static QR code will not change. Dynamic is an editable QR code form. At the same time, it makes the dynamic code technology in-depth research and development further, through the unique technology, through the management platform can flexibly set the rights of QR code, such as access time, right of access to the entrance, ladder control rights, effective code scanning times, etc. This can maximize the security of QR code passage and the control ability of access personnel.

Remote Access right for Visitors.

For visitors, in addition to mobile access control, other identification methods can not achieve remote intelligent services, and QR code access control perfectly solves this problem. Through the direct application of the visitor’s mobile phone or the direct invitation of the internal personnel, the visitor will receive a short message containing the QR code passage certificate, through checking the QR code link can enter and exit the corresponding occasion.

At the same time, QR code access control also has the function to remote control door’s opening, through the mobile phone can remotely control access control, such as for friends, delivery guy open community access control.

QR code is a building passport

During working hours, stepping into the office you will pass through a number of entrances and exits: lobby gate — elevator hall — elevator — company gate — office — conference room — warehouse… If these access controls are card-controlled, then the manager will eventually fall into the lost card – make cards – lost card this vicious circle. If you go in and out of these scenes through face recognition, it may be expensive and unexpected, such as: one day because you are in a bad mood, and no makeup, may lead to face recognition failure, making your bad mood worse.

The QR code access control is very suitable for the construction of the whole office entrance control system. A mobile phone can pass through the entrance and exit of the whole building, and visitors can also enhance the visitor experience by authorizing the corresponding entrance and exit authority. For example, visitors enter the gate by scanning the code, and entering the elevator scan code to open the ladder permission, at the same time, the elevator button automatically lights up, sends visitors to the destination floor, and finally sweeps the code into the company, the mobile phone becomes a unified pass mark in the whole process.

About the video at the begging of the article, the first QR code displayed by our tester is an invalid ticket QR code. When the QR code turnstile gate recognizes this invalid ticket QR code, the turnstile gate displays no passage and will also send a voice prompt of an invalid ticket. Then the tester clicks it. This time it is a valid ticket QR code. When our tester swipes this valid ticket, the QR code turnstile gate displays normal passage, At the same time, it also sends a voice prompt of welcome.

This voice prompt video shows Chinese and can also be set to English. Of course, special language prompts can be customized according to the needs of customers, such as German prompts, Spanish prompts, French prompts, Polish prompts, Arabic prompts, Swedish prompts, Turkish prompts, and other special language prompts.

After testing the basic function and working principle of the QR code turnstile gate, the video then shows the details of the QR code turnstile gate, including the embedded QR code scanner, the sheet metal process treatment of the chassis surface, the workmanship of acrylic, and the detailed display of various components inside the turnstile chassis.
