Now everyone's quality of life has generally improved, not only because of economic development, but also because of the continuous development of science and technology, especially under the impact of the Internet, it has brought us many advantages. For example, in terms of access control, two-dimensional code access control has now broken the traditional access control card, which is not only easy to carry but not easy to lose, but also has strong security performance. Let ’s take a look at the mobile QR code access control scheme.
1.Mobile two-dimensional code access control scheme
The solution to the mobile two-dimensional code is mainly based on the development of the Internet. The mobile two-dimensional code access control solution for mobile phones solves some of the shortcomings brought about by traditional access control. It mainly uses the two-dimensional code identification technology, and then uses Internet technology to perfect the two-dimensional code intelligent access control scanning module and property management. Integration, while also expanding the various services of mobile phone code scanning and opening the door, and truly brings convenient, safe, efficient and stable services.
2. Get the time when the key was generated.
A. Perform the first encryption operation on the value of the time with a preset fixed key to generate a binary string code. B. Read the IMEI code of the mobile phone, and perform the second encryption operation on the binary string code and the IMEI code. Binary code for opening the access control; C. Using the binary code for opening the access control to generate a two-dimensional code image key, which is displayed on the mobile phone display screen; D. The two-dimensional code identification module of the access control device records the IMEI of the mobile phone in advance code;
3. Open the access control through the following sequence steps:
A. The two-dimensional code identification device obtains the two-dimensional code image key by scanning the display screen of the mobile phone; B. Decodes the two-dimensional code image key to obtain the binary code used to open the access control; C. Decodes the binary code to obtain the key when generating the key Time and IMEI code of the mobile phone; D. Check whether the IMEI code is recorded and check whether the time meets the conditions of the access control opening time; E. After the check is passed, open the access control and record the access control opening information at the same time. The QR code image key is abolished.
4. What are the advantages of the QR code access control scheme?
Anyone who has used two-dimensional code access control has a certain understanding. In fact, it is mainly the two-dimensional code scanning technology that is now very popular. It's like the micro-xin or Alipay scan code payment form that we often use is similar. It is not only easy to learn, but also achieves high-quality and stable safety performance, low failure rate, and great versatility.
At the same time, in terms of management, the two-dimensional code access control scheme is also very advantageous. At the same time as the information management is completed, the data can be saved and updated in a timely manner, which can more accurately and quickly grasp the situation of people entering and leaving. And the current two-dimensional code access control also takes into account various functions such as card swiping.
Many people may ask if their phone is lost, is everything in it equivalent to being lost? In fact, the biggest advantage of the mobile dynamic QR code is its high security performance. If the mobile phone is lost, you can directly report the loss from the property and obtain the new QR code to open the door.
