In the intelligent access control system continues to develop today, based on the new technology solutions immediately, embedded modules with the development of the times and the introduction of QR code scanning module for intelligent access control system.
At the beginning of the development of intelligent access control, intelligent access control still has certain defects, for example, the two-dimensional code is not clear, two-dimensional code expiration date and other phenomena, often will make the user's experience become very poor. In this context in another new type of access control into the people's field of vision, that is, the mobile phone on the QR code to align the access control machine on the two-dimensional bar code scanning module for scanning and unlocking. Since the QR code of each user's mobile phone is fixed and contains all the user's personal information, this is safer and more convenient than the previous door lock.
Most of the popular applications in the market for intelligent access control use the 2D bar code scanning module, which has a strong performance and can easily read the 2D code on the screen, paper, plastic cards and other media on the 2D code or bar code, has a perfect integrated design, but only requires a very small installation space, lightweight, and extremely easy to embed into a variety of applications, not only can be embedded into a variety of self-service terminals, but also can be embedded into a variety of Intelligent access control.
In the development of intelligent access control today, especially with the QR code as the ‘unlocking key’ has become a popular trend, providing users with more convenient services, eliminating the need to carry access cards and so on. Therefore, QR code scanning module has become an application trend of intelligent access control is also a popular trend.
