The times are progressing, and with the vigorous development of the mobile Internet, mobile phones have become an indispensable tool in our lives. The two-dimensional code access control came into being. It is an innovative developer in the security market and an important device for the two-dimensional code access control system. So how many identification methods does a QR code access control card reader support?

Looking back at the development of access control systems, intelligence is its development direction, making the security market more dynamic, from traditional door locks to residential smart access control systems, from the initial password and card swiping to more secure biometrics. All of this is the result of innovation and development. Behind this development trend, it is not difficult to find that the development of science and technology has continuously solved the pain points of users. Similarly, people have proposed devices that are more convenient to operate, which has become the basis for innovation and expansion of the security market. The QR code access control system has gradually become more practical and convenient.

When it comes to the benefits of the QR code access control system, when we understand it deeply, we will find that it is an innovation based on user experience, so it is also favored and supported by many users. Nowadays, two-dimensional codes are frequently used in our daily consumption, so two-dimensional code access control is also easy to become the habit of users using access control systems.

Nowadays, the QR code access control system has become more functional and diversified from the initial simple and easy to use, but the same simple and easy to use. So how many identification methods does the QR code access control support? As the name implies, the two-dimensional code access control system must first be combined with a two-dimensional code access control card reader and cooperate with other access control equipment to form an access control system, which is similar to a traditional card reader. It can recognize barcode-based identification codes that extend to QR codes or higher. The commonly used QR code access control card reader can be seen from the label of the device, it has the identification method of identifying QR code, IC card, mobile phone NFC, ID card, and CPU card. Of course, it seems to support so many identification methods, and there needs to be technical support such as chips behind it. The QR code access control card reader adopts dual-core 1G high-efficiency image processor, supports resolution of 40*480 pixels, it adopts automatic induction mode, can quickly read effective QR code, supports USB support and RS485 output, making it compatible with the market Most access controllers and tripod turnstile. One of the QR code access control card readers compatible with 86 bottom boxes is more in line with user experience. To upgrade the QR code access control from traditional access control, users only need to replace the original card reader with the QR code access control card reader compatible with the 86 bottom box to complete the upgrade, reducing installation costs for users.

The QR code supports a variety of identification methods, not only the QR code, but also the traditional IC card, CPU card, and mobile phone NFC. As long as you have a mobile phone, you can also use a more convenient QR code access control system.
