The application of QR code recognition in access control and visitor systems

 

With the rapid development of smartphones, applications such as scanning QR codes to add friends and scanning QR codes to pay have been widely used. The convenience of QR codes has been quickly accepted by people. QR codes can be seen everywhere in shopping malls and supermarkets in China. Even the vegetable market has basically achieved full coverage.

 

In the era when QR codes can be seen everywhere, where did the QR codes come from, and what are the rules? Let us explore it together.

 

First, let's first understand the definition of QR code: (quoted from Wikipedia)

 

A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. A QR code uses four standardized encoding modes to store data efficiently; extensions may also be used.

 

A QR code consists of black squares arranged in a square grid on a white background, which can be read by an imaging device such as a camera, and processed using Reed-Solomon error correction until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image.

 

Two-dimensional codes are widely used on mobile terminals, and they are popularized very quickly on smartphones. So how to bring them into the access control and visitor systems according to the characteristics of two-dimensional codes and the portability of their applications?

 

First of all, the traditional access control system uses radio frequency identification and biometric identification as the main identification methods. The identification code or feature code entered by the system is compared and identified. Among them, the access control card identification requires an access card to be opened before the door can be opened. Portability is tested. Biometrics has its inherent advantages. However, the cost of the equipment with a cumbersome and better entry process is relatively high, and it is not convenient for temporary personnel to quickly register.


The two-dimensional code access control is preferred for us. It is easy to be created and be quickly registered, which is its advantage; the QR code access control and visitor system will perfectly combine portability and security.


For example: WE could configure Network Access Controller connect with QR code reader by Wiegand 26/34output and manage it by software (without extra charge)

Let's take a look at what equipment components are needed in such a QR code access control and visitor system:

 

1. QR code reader: used to read the QR code on the user's mobile phone;

2. Access controller: Determine user permissions and store records;

3. Passage gate or access control electric lock: the equipment to be executed;

4. System management software: manage access control and visitor systems;

5. User mobile phone: store QR code and pass key;

 

With the above equipment, a system that uses two-dimensional codes with both access control and visitor functions can be established.

 

Next, let's see what kind of places such a system is suitable for?

 

1. Office building:


An access control system is indispensable in an office building. It is usually necessary to set up a humanized visitor registration at the entrance. The QR code access control and visitor system can effectively enhance the image of the office building, prevent random entry and exit, and ensure office safety;

 

2. Factory:


The complex entry and exit of factory personnel and the large flow of people bring great pressure to visitor management and also bring safety risks to the factory. Traditional manual visit registration has many security loopholes, inhumane operation, and low service level; the use of QR code access control and visitor systems can effectively distinguish between factory internal personnel and visitors, and solve the problem of inconvenient handwriting inquiries;

 

3. Government departments:


QR code access control and visitor systems can quickly generate QR codes and quickly spread internally. Access control system authority management is relatively flexible and convenient. Access to important places can be combined with dynamic encryption, and the QR code content information is updated every time. It is easy to integrate seamlessly with other systems and accelerate the pace of the humanized office.
