4. How does QR code turnstile work and what are the features of QR code turnstile?
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.
How the QR code turnstile gate is opened.
Today we are going to talk about how the Mairs’s QR code turnstile gate is opened. (The principle is not
complicated)
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.

5. 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.
QR code recognition:

6. 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 the
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.)

7. 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, the intelligence
will be brought to the extreme, among which the most
representative is the QR code access control.

8. Working principle of QR code turnstile:
The QR code turnstile gate is to embed
the QR code scanning head in the gate
and use the QR code scanning to open
the gate to control the staff. Like
swiping IC card ID card, and If adding
card reader and scanning head
together, then can scan QR code and
swipe IC or ID card together.
Working principle: 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.

9. 1. Machine core is composed of special high-speed motor, the door board with fast swing speed, low noise,
smooth operation;
2. Adopts the advanced decelerating motor + coding electric control positioning device, efficiently realizes the
synchronism when the door board swings, the localization accuracy;
3. The best feature of QR code turnstile gate is speed fast, the speed of opening / closing can reach 0.5
seconds ~ within 1 second;
4. Adopts the special ARM microprocessor as the core technology module electrical control system, the
performance is determined and reliable;
5. Has the RS232 standard protocol communication interface, through the computer management system
realizes the remote control to open / close the gate machine, may network the operation, may also run offline,
realizes the gate machine intelligent management truly;
6. Has the-on self-check, fault self-check and automatic reset function;
7. QR code turnstile gate has the traffic red/green light indication prompt function, causes the access to be quick,
accurate, safe, relaxed;
Technical features of QR code turnstile gate:

10. 8. Has strict anti-tail with alarm function and anti-reverse illegal traffic function to ensure the legitimacy and
effectiveness of traffic;
9. Has anti-clamping function, when the door board in the process of closing the door, someone / object
blocking / trailing / forced punching card is clamped by the door board, the door board will immediately force to
open, prevent clipping personnel, and constantly sound and light alarm warning, Until the person / object leaves
the passage, the door board will automatically reset to ensure the safety of passage;
10. Has the fault self-check and alarm prompt function, causes the problem to solve becomes high efficiency,
easy;
11. A variety of mode options, the gate can choose one-way/two-way, swipe card in/out, swipe card out/free
card in/out, fast pass/open function and other modes, to meet the needs of various occasions;
12. After the card reading is valid, the door board automatically opens, and when the QR code turnstile gate
detects that the person / object has passed the infrared sensing area, the door board automatically closes
immediately;
13. Free passage after power off.

11. Follow 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.
Features of QR code recognition

12. The authority of QR code
access control is flexible and
controllable.
We know that there are two forms of QR
code: 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.

13. 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 check 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.

14. 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, no makeup, may lead to
face recognition failure, make 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, enter the elevator scan code
to open the ladder permission, at the same time, the elevator button
automatically lights up, send visitors to the destination floor, and
finally sweep the code into the company, the mobile phone
becomes a unified pass mark in the whole process.
The QR code becomes a building passport.
